 Th specie illoeted heionu to the following trihes: Phalaiideae, Ario.s- 
 tideae, Avri. iie, Festuceae, und Hordeac; of the.se the Festiiceae are the Lest 
 represf . cd They all are perennial and, concerning the hahif, the stoloniferous 
 typo is Mnowhat more frequent than the eaespitose tine; widely creeping .stolons 
 alxjve R ,iu.id are characteristic oidhjccria vilfuiilai; sulilorranean ones of I'oa 
 arctica, Aictagrostis, Ihipontia, Ftslnai rulirn var., Ehimiis, Arrlophiln, and 
 Alopecuius; in the last throe genera the stolons attain (piile a consi(ieral)le 
 length and ramify freely. The cu'ms are ahvavs simple and usually short, 
 pspecially so in aii/ceria teiiclh and f/. vilfoiili'n. while in Kli/mim, Arctophila, 
 Arctddnisli.t, and Dupoiitiu, the height of the culm may reach forty cm. or even 
 a little more. The inflorescence is most often an open, lax-flowered panicle, 
 notahly so in A tophiln, Diipo/itin, nud Pmi arrtica: a contracted, spike-like 
 inflorescence occurs in Trixrtum, Aloprnini.i, and Calnmaiirotitis; a spicate one in 
 Elymii/i, Agropyrnm, and Ilordeum. The flowering glume ' is more or le.ss hairy

 The spikclets (Fig. A: 1-2) are from a tvpicn.l specimen collected on Wolla.ston 
 land. 
 
 In f\ ahbrciiatn the broad empty glumes as well as the flowering glume, 
 the latter being puberulent on the sides and along the keel, constitute a good 
 distinction, when compared with /■•. glauca, in which the glumes are much 
 narrower, and the flowering glume hairy only on the keel. 
 
 P. arctica R. Br. 
 
 There is no doubt about this being the same as P. flcxunm Wahlenb., but 
 it is debatable whether it is to be considered identical with P. ccnisia All. 
 Lange (I.e. p. 178) states for instance: "Nomen P. cerisia All., quod a pluribus 
 autt. hue relatum est, non ad hanc speciem spectare videtur, si cum Gren. et 
 Ciodr. ad P. dislichophyllam Gaud., a nostra l)ene distinctam, P. rcnisia »it 
 .synonymon ducitur. 
 
 "P. arctica R. Br. vero ex consensu plur. autt. omnino eadem cum nostra; 
 utrum horum nominum praeferri debet, incertum videtur, cum uno eodemque 
 anno (1824) publicata sunt." 
 
 As pointed out by Lange, (I.e. p. 178) P. arctica is readily distinguished by 
 the spreading, flexuose branches of the short panicle; by the ovate, 2-4- flowered 
 spikelets of which the glumes are purplish and of which the flowering glume is 
 obtuse or roundish at apex, with a broad, hyaline margin, villoii-s at the base, 
 and pilose along the veins. The rhizome is stoloniferous. 
 
 Arctophila Rupr. 
 
 The old genu? ' ulpodium of Trinius ■ was founded u|X)n two species: mon- 
 andrum and Steveni, which by Trinius himself were considered as "species facie 
 dissimiles," and they are indeed so unlike that Robert Brown ^ a few years later 
 .segregated the former as Phippsia algida R. Br. and retained the latter only as 
 a Colpodium. To the latter genus was furthermore referred C. lalifoUnm R. Br. 
 although Robert Brown was not certain about the real affinity of this species 
 to those of Trinius and especially not to C. Steveni and comprefi/<iari. At present 
 Robert Brown's species lati folium is generally placed under Grisebach's genus 
 Arctagrontis as ,1. latifolia (R. Br.) Griseb. 
 
 While Colpodium of Trinius was adopted by Gri.sebach ' with the omission 
 of r. monnndrum (Phippsia). the genus was nevertheless augmented with certain 
 species placed as a .section "Arctophila" in contrast to C. Steveni and its natural 
 allies representing the section "Eucol podium." By including the species of Arcto- 
 phila Rupr., the npnns Colpodium became actually an aggregate of incongruities, 
 as it had been before with Phippsia and Arctagrostis included. By Bentham the 
 genus was finally restricted to the sccilon Eucolpodium, while Arctophila became 
 transferred to Graphephorum Desv., next to Glycena R. Br.; another disposition 
 was made by Hackel who followed Grisebach by placing lK)th Eucolpodium and 
 Arctophila as sections of the original genus Colpodium, characterizing them as 
 h.aving the ".spikelets one to two-flowered, etc." This same classification is 
 also followed by Beal ♦ in nis Monograph of North American Grasses, with the 
 same erroneous characterization; erroneous, itecause it was originally intended 
 for Colpodium alone in the sense of Trinius.

 Three species are enumerated by lieal as reprcsontativos of the genus 
 Col-podium in North America: C.fulvum (Trin.) Griseh., C. pendulinum (Laestad.) 
 Griacb,, and C. mucronalum (Hack.) Real. Considerinc ihe fact that Colpodium 
 in the sense of Trinius was originally intended for both ( . Sicveni and Phippsia 
 algida, it seems difficult to find any good ground for admitting species of so 
 little affinity as those of Arclophila and still crediting the genus to Trinius. And 
 the species of Arclophila have themselves been transferred from one genus to 
 another. Thus we find them as members of Poa, Glycerin, (Iraphephorum, and 
 finally of Colpodium. 
 
 Considered by themselves, the species of Ruprecht's Arclophila ' constitute 
 an excellent little genus, and we might cite Ruprecht's own words when he 
 proposed the genus in his "Flores Samojcdorum cisuralensium": 
 
 "Arclophila a Calabrom (airoide) praesertim difTert glumarum conforma- 
 tione et longitudine, hac not a etiam et insuper valvulis ecostatis a Glyceria R. 
 Br. recedit. Atropis Trin. {P. distans) Catabrosae quoad gluinas proxinna, 
 spiculas habet (saltem in statu virgineo) lineares, fere teretes; in Arclophila 
 nostra semper ex ovato-oblongae vcl lanceolatae. Conjunctioni Arctophilae 
 cum Poa obstant: valvulae dorso concavae vel saltern minus compressae; flosculi 
 lana nuinquam cincti, nee ad norvos dorsales sericei, sed ad callum more Aven- 
 acearum pilis rigidis obsiti; valvula inferior apice vix integerrima, sed margo 
 plerumque irrcgulariter denticulatus et erosus, saltem crenulatus et apex saepe 
 obtusus vel truncatus; habitus etiam nobilior colore fulvo paniculae saepe 
 intermixto; spiculae majores plerumque et flosculi demum patuli, remotiusculi." 
 
 The species that are best known are: Arclophila fulva (Trin.) Rupr., A. 
 pendulina (Laest.;d.) Ands., and A. effusa Lge., especially the first of these 
 since the Greenland plant, A. effusa, was for many years considered identical 
 with A. pendulina by Fries, Grisebach, and several other authors. 
 
 The species found by Mr. Johansen is .4. effusa Lge., described in Conspectus 
 Fl. Groenl. as follows: "Satis superque difTert planta groenlandica, in Fl. Dan. 
 tab. 2343 nomine Poae pendulinae divulgata, a Glyceria pendulina Laest. vera, 
 Lapponiae tornensis et rossicae incola, statura liumiliore foliis brevioribus, 
 culmo erecto (nee apice nutante), ramis deflexis, in verticillo 1-2, raro 3, flosculis 
 in spicula 2-3 (nee 3-6) minus laxe disjxjsitis, glumis obtusiusculis, spicula panim 
 brevioribus, etc. Rotanici plures (I. Vahl, Fries, Ledebour, etc.) has 2 species, 
 inter se valde dissimilcs, infauste junxerunt, quarc plantam Groenlandicam I.e. 
 nomine novo designare coactus sum." 
 
 West Greenland, between 64» 10' and Go" 20', in damp situations, very 
 rare; Sukkertoppen, Godthaab (Vahl). 
 
 A depauperate form of this species is known from Spitzbergen, formerly 
 considered as distinct and named Colpcdium Malnujreni Ands.* 
 
 While Grisebach (I.e.) only recognized .1 . fulva and A . pendulina, seven other 
 species had been described by Ru))repht (I.e.) but merely referred to as synonyms 
 in Flora Rossioa; Ihey wore rollectod on the island Kolgujew and on the Russian 
 coast near Kainljaliiitza and Hjolaja. 
 
 The genus seems to be rare in North America, l)ut specimens belonging to 
 it have been collected in various parts of Alaska and adjacent islands and al.so 
 in Canada. The<e speci.nens iiavo been generally identified as A. fulva or A. 
 
 pendulina: of th(>so 
 Hudson bay region, 
 on this continent. 
 In the copious 
 
 the former is known only from Muckelung river and the 
 and. so far as I know, .4. pendulina has never been fourd 
 
 material sent to me for identification from the Canadian 
 Government, I found four species, which appeared di.stinct, and of which three 
 have been described and figured in my paper; On the genus Arclophila Rupr.*

 ■D ^^^ fPfcies A. gracilis nob. from north of Lake Superior, collected by Dr. 
 K. bell; .^1. brizoides nob. from St. Paul island, Bering sea, bv James M. Macoun 
 and A. chrysantha nob. from sixteen miles west of Nome city, Alaska, by J. b' 
 • . "•, ^furthermore A. trichnpoda nob. from Mansfield island and Nottineham 
 island Hudson bay, collected by Dr. R. Bell, and of which the diagnosis » reads 
 as follows : 
 
 I r '''^toloniffrous: culms weak, about twenty cm. in height, enclosed by the 
 leaf-sheaths: leaf-blades broad, flat and glabrous, longer thpn the internodes- 
 inflorescence a lax-flowered panicle with the glabrous, capillary branches in 
 twos and threes: spikelet three-flowered, one or two on each branch: empty 
 glumes unequal, quite broad, acuminate, membranaceous, three-nerved- flower- 
 ing glume broad, pomted and often awned, at least in the basal flower, hairy at 
 the base: palet bidentate, shorter than the flowering glume. A rear ally of A 
 mucronata Hack." 
 
 Finally may be mentioned that John Murdoch collected an i4 rc^opAi/a near 
 I'omt Barrow which Hackel has described as A. mucronata, fide Beal: Grasses 
 of North America.' The diagnosis reads as follows: 
 
 "A smooth, stout grass, 15-25 cm. high. Leaves 6-8 in number crowded; 
 liguie broad, lacerate, 2 mm. long; blades flat, abruptly poinded, 5-12 cm. long 
 b m.m. wide. Panicle shining, yellowish, open, partially included, narrow or 
 pyramidal, o-7 mm. long, rays in twos or fours, reflexed, the longest 3-7 cm. 
 long, bearing 2-3 spikelets near the apex. Spikelets 2-flowered, joint of rachilla 
 U,b m.m. long, smooth or very sparingly hairy; empty glumes subequal, 3-3, 
 I r"-™- 'Ong soft, .:iin, first ovate, l-nerved, second broader, 3-nerved; floral 
 glume broadly oval, 3,5 m.m. long, 3 mm. wide, 5-nerved, margin scarious, 
 apex irreguk-rly toothed or torn, the central nerve extending to the tip or into a 
 short mucro; palea broad; 1,5 mm. long." 
 
 It is thus characteristic of A. trichopoda and A. mucronata that the midrib 
 of the flowering glume is extended into an arista in the former, and in a mucro 
 in the latter while in all the other species the midrib does not extend beyond 
 the apex of the glume, a structure which certainly would be anomalous in the 
 genus Colpodium Trin. (as understood by Bcntham), because there the midrib 
 never reaches the top of the glume. 
 
 These species of Arctophila may naturally be classified in two sections: 
 
 L Macrostachyae. 
 
 Spikelets, when fully developed, five- to seven-flowered, the base acute during 
 anthesis. 
 
 A. fulva, A. remotiflora, and A. pendulina. 
 
 II. Brachystachyae. 
 
 Spikelets two- to four-flowered, the base obtuse during anthesis. 
 
 i4. brizoides, A. chrysantha, A. deflexa, A. gracilis, A. latijlora, A. mucronata, 
 
 A. poealantha, A. scleroclada, A. similis, and A. trichopoda. 
 
 Dupontia R. Br. 
 
 , The genus was established by Robert Brown » and characterized as follows- 
 
 Gluma subaequivalvis, scariosa, concavn, mutica, lociistarn 2-3-floram sub- 
 
 aequans. Perianthia mutica, scariosa, (basi barbata), altcro pcdicellato; valvulis 
 
 integris, inferiore concava. Lodiculae 2. Ovarium imberbe. Stigmata sub- 
 
 sessiha. Caryopsis . Grarnen glabrnm erectum. Folia linearia, plana, 
 
 vaginis semifissis, basi integra. Panicula simplex, roarctata, fusco et purpur- 
 ascenti varia, pcdicellis cum locustis continuis, perianthiis separatim solubilibus." 
 The genus was named in honor of Monsieur Dupont of Paris, author of a 
 valuable essay on the sheath of the leaves of glasses, and of observations on the 
 genus Atriplex.

 Only one species, D. Fischeri, wasknown to KoIkti Rrowii, hut sinon then 
 Ruprecht (I.e.) has described a second one, D. p/'ilosdnlhn, from Kolnujew island, 
 and a third one, I), micrantha nob., has been found in Luurador: Halton, and at 
 cape Henrietta Maria, Hudson bay. 
 
 Of these D. psilosantha differs from D.Fischeri by the empty glumes being 
 "acutissimae, caudatae," and by the flowering glume being "(fioseuli) gluberrimi, 
 acuminati," while in D.Fiitchcri the empty glumes are more or less obtuse and 
 the flowering glume obtuse and pilose at the base; the third species, D. micranlha, 
 differs from Ixjth by the small size of the mostly one-.'ioworcd spik<lots, etc. 
 according to the diagnosis:' 
 
 "Stolonifcrous: culm slender, glabrous, about twenty-five rni. in height: 
 leaves very narrow, glabrous with prominent ligule: infiorcscrncc a contracted 
 panicle with capillary branches: spikelets one or two on each branch, mostly 
 one-flowered: empty glumes unequal, very narrow and sharply pointed, mem- 
 branaceous: flowering glume acute, slightly hairy at the base, not exceeding the 
 superior empty glume: palet bidentate, a little shorter than the flowering 
 glume." 
 
 Glyceria R. Br. 
 
 The segregation of Atropis originated with Ruprecht' and was accepted by 
 Grisebach in Flora Rossica: "genus a ilbjceria imprimis stylo ad basin usque 
 simpliciter plumosa distinctum est." Meanwhile Parlatore ^ established the 
 genus PvrciucUia containing the same species as Atropis and formerly by Elias 
 Fries* referred to his section Hchochloa of (Hiiccrin. According to Fries (I.e. 
 \MiS) Glijccria consists of two sections: " Ili/drochlun Ilartm.," with the flowering 
 glume 7-nerved, and " Heleochloa Fr." with the flowering glume o-ncved. 
 
 As a section Atropis has been recognized by vai'ious writers, and much more 
 so than Puccinellia. Buchenau ', however, treats67(/cen'a and Atropis as distinct 
 genera, and this author is one of the very few who furnishes a sufficiently com- 
 plete diagnosis. In Gray's Manual (1908), PyccincUia is accepted as a genus, 
 though poorly defined as distinct horn Glyceria; more recently we find the same 
 disposition by Fernald and Weatherby (Rhodora lOlti), enumerating eleven 
 species as indigenous to eastern North America south of Hudson straits. 
 
 However, in giving Puccinellia preference to Atropis Fernald and Weatherby 
 have certainly misunderstood Ruprecht, because this author has clearly demon- 
 strated that he considered Atropi't and some other genera as being distinct from 
 Poa. And when Ruprecht states that: "E conditionc glumaruni generum 
 series fortasse sequens: Diipontia, Arctophila, Pon, Atropis cet," this author did 
 not mean that these: "from the condition of the glumes perhaps represent a 
 series of genera as follows: Dupontia cet.," but that the genera mentioned might 
 be arranged according to the structure of the glumes, as enumcratecl alxjve; 
 series means in this connection sequence referring to the arrangement. More- 
 over, it seems unjust to ignore Atrojiis because tin; diagnosis of Puccinellia 
 by Parlatore is more complete; if such procedure be considered "the best for 
 serving the cause of sound nomenclature," as claimed by these authors, very 
 many gen(>ra of Linnaeus would suffer > same fate. 
 
 By comparing the species of Oiy the classification proposed by Fries 
 
 (I.e.) apprars the most natural, retaini: .le gentis intact, as has been proposed 
 also by Duval-Jouve in his classic treatise: Doiites ct pridres au sujet de quelcjueb 
 esp^ces do Glyceria du groupe des Halophilcs.^

 For a comparison I have drawn the spikelets of l)0th (Fig. A: 4-.^ and (i-7). 
 
 Moi cover, as pointed out by Johanson (I.e.), the structure of the stolons 
 differs in a marked degree from that of the other species of Glyccrla, and seems 
 indeed to be rare, or at least but little known from Gramineae in general. The 
 accompanying te.\t figure (B) shows part of a stolon of tf. vilfoidea (tig. 1); in this 
 the main shoot is aerial (S), and b"nr.^ several green leaves, .scparntcd from each 
 other by stretched internodcs; at cacli node a small lateral shoot is developed 
 (L), of which the first leaf re[)rcscnts an adorscd prophyllon (F) or fore-leaf, as 
 is the usual structure of lateral sho'"*s in the monocotyledons. But, as may 
 be seen from the drawinr the lateral shoot is not situateil in the axil of the 
 corresixjnding stem-leaf, 1 has been moved up to the node al)Ove, thus occupy- 
 ing a very strange |X)sitio remote from the ieaf-a.xil. It is a structure that 
 recurs in the genus Caiahrom, for instance, inf. aquatica (L.) Beauv., where the 
 structure is very plainly visible (tig. 2); in this plant the stolons appear to root 
 more freely, the secondary roots proceeding from the nodi, as shown in the 
 drawing. 
 
 The fact that (V. vilfoidea seldom produces flowers, and that fruiting speci- 
 mens are almost unknown, indicates that vegetative reproduction supersedes 
 tlie floral, and in this respect (7. vilfoidea is readily ilistingui.shcd from the other 
 species of the genus. While vegetative reproduction is known to be prevalent

 stolons developed from the basal leaves. In Aim alphia, for instanee (fiff. 3)i 
 the spikelets are transformed into leafy sh(K)ts, since the flowering Rl.ime, the 
 palet and the sexual organs have developed in the shape of green leaves with 
 sheaths and blades, whde the empty glumes show the tvj.ioal structure of 
 glumes A simdar transformation of flowers into leafy shoots is known also 
 irorn the arctie-alpme Polygonum viviparum, from some of the Saxifragae ,S'

 Since I described this species a revision of the genus Puccinellia in eastern 
 North America has been presented by Fernald and Wutherby, in which several 
 now .stations have been recorded from the coasts of Labrador, Keewatin, Ncv/- 
 foundland and Quebec, besides that two varieties have beer d< scribed by these 
 authors: alaxknnu (Scribn. et Merrill), new comb., and longiqlumis n. var., the 
 latter from Prince Edward island. 
 
 According to the revision, cited above, the var. ahsknna has been pas.sing 
 very generally in eastern America as Puccinellia arigui^lata, based u|X)n Poa 
 anguslata R. Hr., as for instance, by Simmons (\'ascular plants, Ellesmereland, 
 1900), whose specimens thus belong to the variety of ,.nupcrcida.

 The genus is [KJorly represented on the aretie coast explored by the 
 expedition and C. incurva is the only Vignea collected. With regard to the habit 
 the stoloniferous speries are more frequent than the caespilose, uiid they ail 
 are "phyllopoilae." This character "phyllopoda" implies a biologic |)eculiarity 
 which is possessed i -pecially by northern types; it consists in the sli(M>t being 
 dicyclic, i.e. vegetative in the first, floral in th(> second season, with the rami- 
 fication of the shoot s;,ini)odial. Moreover, in this type the very young iiillores- 
 cense is j)roteeted by being surrounded and covered by a nuiid)erof leaf-sheaths. 
 The inflorescence thus terminates fh' shoot and when the fruits have matured, 
 the main shoot flies off completely while a lateral btid developed in the axil of 
 one of the basal leaves continues the growth of the rhizome and repeats the 
 succession of a vegetative and Horal stage. Otherwise with the "ophyllopodnr." 
 In these, principally southern species, the shoot is most often pliocyclic with 
 reference lo the \eg« taii\e Stage but nioncx yclic as far as concerns the floral. 
 For in the aphyllopoilae the ramification of the shoot is most frequently mono- 
 podia!; however, there are :!Ome species which, although being aphyllopvdae, 
 show a sympodial ramification and in which the very condensed rhizome, mostly 
 more or less caespitose, develops a number of purely floral and purely veget iive

 The primary root was not preserved in any of the specimens collected. For 
 a comparison I have also examined material from I'ort Clarence. Al.aska, from 
 Moosehide mountain near Dawson. Yukon, ami from Jakiitsk, Siberia. Subter- 
 ranean stolons are developed with iiiinule sialr-like hvves and w ith stret<'lied 
 inlernodes: c.ipill.ary .secoiKhiiy roots develop freely from the nodi. The aerial 
 shoots are lonji. prostrate, very leafy, and while many remain purely vegetativi' 
 during the lirsl season, some others deveio|) a siiifrle, terminal flower: very 
 often a loiifl vejjt tative branch may dc \el(ip from the axil of one of the leaves 
 beneath the flower; thus it may look ,is if ilie liower were lateral but it is only 
 a|)i>:iientl\- .so. The prostrate ;ieri il sliools develop no roots in the first year 
 but in specimens which represented ba.ses of old shoots riK,' ■ere present, and 
 these b;is.'d stem |M)rtioiis had jiiadually become iiuried in the .-oil. ( 'h.ar.aclei istic 
 of Mirrkiii is thus the ;ibilily to wander not only by means of -iibterraiiean 
 .stolons but also by m(>ans of the loiiji, prostrate, .aerial shoots.

 Mthoiinh al.selit from ( iieeiij.iiicl. Spit/herKeii and Iceland, (■aUhit piiliixlnx 
 nevertheless is eirciim|K.lar ; farther south it is widely disfrihuled in I.uroiie, 
 Mini on this continent it o.'cms in the Atlantic States east of the Mississippi, 
 from the nioiintains of Carolina and Tennessee northward to Newfoundland, 
 theii.'e west to Minnesota and Saskatchewan: in some forms and varieties it 
 occurs also in Alaska, alone the norlheni coast of Canada, and in arctic Siberia. 
 Naturally the species exhil.its a somewhat dilTerent lial.it throughout a raiifje of 
 -iich enormous extent, and it seems more safe to conclude that the species is 
 iy)lvmorpliic. rather than to consider the modihcatton in liahit as lieinji of 
 specific imixirtance. This iiiav he ivadily ai.preciated when we compare the 
 species as it occurs in the tem|»'iale renioiis of lioth Worhls with the types 
 known from the more northerly latitudes. 
 
 In Norwav, Mcco'-dinn to IMvtl (I.e.), the stem is ascendmn from a decumb- 
 ent, sometimes nM.tiiiK base, and the foliane shows :i reiiiform outline with the 
 martlin ereliate; speeimeiis with the stem nMilinjr are by this autiior relern'd to 
 the forma rmllnnis Korst.. known especially from Dovre mountain and IinmarK. 
 In Swe.len the tvpical plant is common but llartmaii records aNo the lornia 
 riiilicaiin beside a form of diminutive size with the leaf-niarKin entire instead of 
 eleiiate III Hilssia, LedeUmr .{escribes the plant as li;iviii(i an : leci or aseemling 
 siem with the leaves >ulK)rl)icular or reniform, crenate alontj the marum; fmther- 
 more the f.niii with the stem roolinnis also recorded by this author. Aseherson 
 describes the Cerman plant as having cordate leaves at tlie base but remtorm 
 above- Hiichenau'' makes the same statement but adds that all the leaves are 
 er.Muite- this author made also the observ;iti.)n that the variety huln hehott, in 
 which the follicles are erect, was the most abundant while the var. tm'irn luth, 
 with the foUh'les icciirved. appears to be very r.are. In France 'Ciillhii i>nliislns 
 is ciuite freiiiient, and the leaves varv from reniform to somewhat cordate but 
 alwavs witl. the maifrin <renu1,-ite. According; lo .Mathieii' the basa le.ives of 
 the Belfiian plant are sulxirbicular, iviiiform, ami cnMiiilate at the base wiiile 
 the eaiiline are ereniilate all round. ' 
 
 \ similar leaf-shape is also characteristic of the .\merican plant , and I orrey 
 describes this as "orbiciilate-coi<late or reniform, obtusely crenate, or nearly 
 entire-" a varietv Inlcqcrrimo {('. inkgrrrimn I'ursh) is also mentioned in which 
 the basal leaves arc wiioUv ontiio but the cauline obscurely crenate. In (.ray s 
 Svnoptical Mora a varietv ntih'anis Cray is described, the leaves varying iroin 
 "dilated-reniform to near'lv truncate at base:" and a<-<-or(hns to this author C. 
 miliriiHs Forst.. ('. usarifol'ia DC. C. nrclim K. l?r., and C. imliistns var xibirica 
 Renel are merclv svnonvms of this variety. Finally may be mentioned that in 
 sCHue specimens from St. Croix Falls, Wisconsin, the inartjm is entire m the 
 basal ,as well as in the (-aulim- leaves, and the outline of the blade vanes from 
 reniform to eomph-tely round in the basal foliage while the stem-leaves are

 According; to Lanjio (I.e.) U. ajjinis is very rare in Greenland: it is known 
 from Kast (ireenland: Fr. . Joseph's fjord 73°, and from West fircenland: .\r.salik 
 in I.sortok fjord. I-'roin the latter station .some specimens have been figured in 
 Flora Danica \'ol. 17. Tab. 3029 (1SS3), and these specimens give a good ropre- 
 .sentation of the s|)ecies as well as thi^ photographic icprodiiclion of specimon.s 
 from IlarlKiiir fjord in Simmons' Flora of llllesmero Land.'- On the accomp.any- 
 ing plate I have figured a flowering specimen from Bernard harUnir and an 
 acheno taken from a fruiting specimen from l^pwortii harlMiur: the leaf (Fig. 
 2) is from Bernard IiarlKiur. 
 
 While the ty])ical s|)ocies occurs in Spit/bergen, according to Xatliorst,' 
 this author found al,-o a plant which proved .<o dilToierit from lyjiical A', ajjluii 
 that he described it as a subspecies: Wilaiitkrl. Xathorst calls attention to the 
 following distinctive character^ [los.sossed by this subsiiecies: it is of low stature 
 and caes|)itoso: the fruiting head is roundish, not cylindrical; the carpels are 
 thinner, with the body only a little longer than the recurved, rather coarse beak. 
 A figure is giv(>n by Anderson and ll(\sselm:ni in their interesting aocfiunt of 
 the Fulcra of Spitzbergen and Rooren F'.iland (I.e.). ,1. Froyn, however, ("in lit- 
 teris," compare Andor.s.son and liesselinan I.e.) on examining this plant as well 
 .a.s the material of typical A', (jffmi.^ collected by these authors, has reached the 
 conclusion that the specimens must be referred to R. arctinifi Rioliards. and that 
 R. offuiis does not kiow in Spit/.bergen at all: fiirtliermorc, this author in.si.sts 
 that all the material from Siberia, Daviiria and Spitzbergen named R. nffinis is 
 actually 7?. arcticuf:, and that R. nffinis is confined to western North America, 
 viz.: the Rocky mountain;-, extending from there to Melville island. This 
 statement .seems rather peculiar when wo remember that Richardson's R. 
 arclicvs came from arctic North America, collected on the first l'>anklin ex-

 In Gray's Synojjt. Flora (1895-97, p. 29), the spccii -: is inciiiioiuMl only as 
 a eynonyni of R. pyqmai us Wahlenb. 
 
 Tlie affinity of tlio species is undoulitedly with /.'. iii/iinuic.its Wahlcnl). 
 and several specimens whicli I have examined may well lie mistaken for large 
 s|)ecimens of the latter, notably some collected l)y Simmon- in ICIlesmereland 
 (Aluskox fjord); more typical arc the specimens from Cape J5athurst which are 
 of considerably larger size with resfjcct to fcliage and flowers, and in some of 
 these the fruiting stalk from the year previous is still preserved; it is strict and 
 measures the height of It cm. The specimens from I']llesmer(lan(l, on the otlier 
 hand, show the fruiting stalk arched and bent toward the ground as in R. 
 pygmncus. R. Sabinii is |)erennial, of exactly the same haliit as R. 'lintJif; and 
 affinis as far as concerns the rhizome, the roots, and the inliorescenee. 
 
 PAPAVERACEAE. 
 Papaver nudicaule L. 
 
 According to Tr. Fedde ' the jjlant iVom the arctic and northern part of ihe 
 subarctic countries r' presents the sulispecies P. radicdtinii (Hottl).) Fedde; 
 specimens were collected at many stations visited by tb expedition. 
 
 'i'lie species is perennial with the primary roots jiersisting for several years 
 as a deep and relatively thick tap-root which })ears many slender, lateral rami- 
 fications. Several erect or ascending shoots proceed frr)m the crown of the root, 
 and, on reaching the surface, they develoj) green leaves and lJower-l)caring 
 stems, each with a single flower. Large specimens are thus of a caespitose growth 
 in which the leaves form crowded rosettes like cushions, reaching the width of 
 about 12 cm.; in such sjiecimens the munerous shoots may reach the length of 
 aljout .5 cm. I)eneatb the smf.ice; they are densely clothed with tl>c persisting 
 leaf-sheaths from previous ye.irs. In the tallest specimens the flowering stem 
 measured alx)ut 14 em., the fruiting one up to about 22 cm., but most of the 
 other specimens were much lower. 
 
 CRUCIFERAE. 
 
 Lesquerella arctica (Rich.) Wats. 
 
 This is a perennial herl) with a deep, slender, freely branching, persisting 
 priinary root crowned with a compact rosette of leaves from the axils of which 
 the ascending flower-bearing stems arise; the ramification of the shoot is thus 
 inonopodial. The rosette of the largest specimen measured C cm. in diameter; 
 the height of the flowering stems was about 10 cm. 
 
 Cochlearia groenlandica L. 
 
 Collected as late as the tenth of August, at Bernard harbour, several minute 
 specimens were commencing to bloom; in these the diameter of the rosette 
 measured onl\ U cm., the height of the flowering stem 1 cm., and tlie very tliin, 
 primary root al)Out 4 cm. in length. Such small specimens were growing with 
 large ones, about •") cm. high, and with almost mature |X)ds. 
 
 Drabn alpina L. 
 
 A large number of specimens were collected of this species, the largest 
 forming a compact cushion me.asurinff in diameter 10 cm., with tlie flow-ering 
 stems only 3 cm. in height. The primary root persists throughcat the life of 
 the plant and attains a considerable length, but is generally slender; only in one 
 specimen did it measure al)Out 3 cm. in thickness. In some very old specimens

 D. hirta L. 
 
 D. hirta L., on the other hand, doe< not .<eem to persist for so many years 
 as the three foregoi ig species. It is a tall plant as compared with most of the 
 other Dmbac, reaching the height of al)out 20 cm. when in bloom, such specimens 
 having been coIle<ted on the south coast of Coronation gulf. The primary ro«it 
 is relatively shor' anc' thin and only a few rosettes of leaves are developed, each 
 of which is terminated liy an inllo.-escence. 
 
 Braya purpurascens (H. Hr.) Bunge. 
 
 Has a mono|)odial sjioot, the youngest specimens showing very plainly a 
 eentral leafy a\i> and two lateral inflorescences; in old specimens the rainihca- 
 tion is ob.scured by the .everal leafy shoots being crowded, and the lateral 
 position of th.^ tloial stems is only indicated by the.>(> being ascending, not 
 strictly erect. 
 
 B. glabella Richards. 
 
 Only a single specimen was collected of this very rare species, known only 
 from the arctic coast of this continent, from East Creenland, and from a few 
 station^ in arctic Scandinavia. It is readily distinguished from B. purpurascens 
 bv the leaves being remotely dentate, and by the long, linear pods. 1 he speci- 
 nien from Wollaston lan<l measured a iieigh.l of aiiout 12 cm., and although being 
 a young spe.amen eleven flowering stems were developed from the small rosette 
 of leaves; the primary root is relatively short, slender, and much branched.. 
 
 Eutrema Edwardsii R. Br. 
 
 In voung specimens the primary root is sh'iider; there is no rosette and only 
 two to"'''ree long-petioled leaves at the base of the single, terminal, flower 
 bearing stem. In the ohler specimens the primary root is quite thick, ( istiiictij 
 wrinkled and as manv as six flower-beari-ig stems are developed from the crowr 
 of the root, besides several green leaves. The height of the flowering stem aggre 
 gated about 15 em., that of the fruiting stem very nearly 20 cm. 
 
 Hesperis Pallasii (Pursh) T. el Gr. [//. pygmaea (Adams) Hook.] 
 
 In Gray's Synoptical Flora it is described as a dwarf biennial plant, but 
 according to the' numerous and exceedingly well preserved specimens coUecttv 
 by the expedition, it is a perennial and not always of dwarfed stature either

 branches ecuialling the primary in length. 
 
 Cardamine pratensis L. 
 
 This seems to thrive well on the arctic shore; the st)eciiiiens are tall and 
 bl(K)ming freely; a specimen from Port l^pworth hail)Our me.isures 2\ cm. in 
 height and bears three lateral racemes developed from the axils f)f the eauline 
 leaves. It is a [H)int of interest to notice that in some of these high northern 
 S|)eciinens (roronation gulf) vegetative reproduction is seciueo by means of 
 adventitious be, Is (leveioj)ed u|H)n the basal leaves clo.se to the leaf-segments. 
 Tiiese buds u;K)n the leaves of Cardnniinc w(>re described ..Iready by Cassini; 
 while still in jonncction with the leaf they develop some small leaves and roots 
 and, when liberated, they continue their giowth and develop new independent 
 individuals. Similar buds are known a'so from a few other plants. Turpin 
 observed them in Ornithoqahnn, llen<low in Malaxii^, and according to Lindley ' 
 the> alx)und i" liryvphi/Uum and Ttllimn (jrandi flora. 
 
 With regard to the fruit in ( rilnninir. the siiecimens showed mostly flowers 
 and only a few young pods were 'r\elop(><l. Thus in case of failure to i>roduce 
 seed,^, Carilawine would be able to iieconie distributed by means of the adventi- 
 tious buds. 
 
 C. digitata Rich,'.rds. 
 
 In a monograph of the genus Cardainiiic (). E. Schiilt;; - ri'jeets Richardso 
 name "difjiUitn" because the genus h.as become merged into the genus I)uduri<; 
 of which there is a species "digitutii" of older date, thus necessitating the creation 
 of a new name for Richardson's |)lMiif. 
 
 ''Ihiitiirin diqilatn Lamarck" must eonsequenlly be renamed Cardominc 
 digilala (Lam.) Schultz, and "C. digitata Richards." must bear the name Carda- 
 mine hyperborva Schultz. Howcv r. it all depends on the conc(-pt of the two 
 genera Cardamine and Dintaria, whether they should be kejit separate or be 
 united. This question has been raised before by some of the ablest l«if;tnists 
 abroad and on this coiuinent and the question seems to lie well solved by firay, 
 (Jreene, Xultall. Sereno Watson, and several others who were familiar with the 
 species of lK)th genera as represented on this continent, maintaining the ticnus 
 Dentaria as distinct from Cardamine. 
 
 With respect to the subterranean stni, ('. digitata jiossesses a -lender, 
 horizontally crcei)ing rhizome which bears aerial, green leaves .'ind which is 
 also stoloniferous. In this way the species is better ecjuipped lo become dis- 
 tributed than C. pratensis in case of failure to produce mature seeds in unfavour- 
 
 able KCafsOiis. Rv the consfantlv .smaller size of

 species is perennial. 
 
 Sisymbrium sophioides !■ isch. 
 
 On Ilerschel island this species may persist for more than one season, n 
 shown by a very largo si)ecimen with six flower-bearing stems reaching th 
 height of al)Out 80 ctn. and arising from a large rosette of leaves; the thic 
 primarj' root boars evidence of having been rctivc for at least two seasons 
 The specimen was collected in the month of .\ngust and with it several nnic 
 smaller specimens were collected. Averaging only 3 to .') cm. in height, thes 
 plants were in bloom, and the rosette of leaves was iierfcctly fresh; thus the 
 might be able to winter over. It deserves attention that this species is generall 
 described as an annual and that it occurs as such in arctic Scanilinavia (70'' X.L 
 according to Blytt;' it has also been found near Ivigtut, on the west coast c 
 Greerdand, but as an introduced weed only.

 Parnassia Kotzebuei Cham, et Schl. 
 
 The species is caes|)itose with a very short, erect, sulite'raneaii stem from 
 which numerous lotiK, slender, secondary roots are developed. There are no 
 scale-like leaves, and the foliage forms a small rosette from the centre of which 
 the flower-lieariiiK stems arise. .Induing from the structure o' -ome younc; 
 specimens, it appears as if the first Hower-liearing stem terminati he (irimaiy 
 shoot, and the vegetative re|)roduction is secured by means of o. or several 
 buds developed in the axils of the rosette leaves. These buds may be purely 
 vegetative for a .season or so and they may be separated from the mother plant 
 and give rise to new individuals. Heside these vegetative buds there are also 
 some others which are floral and develop during the succeeding year. \o 
 distinction was to be observed with regard to the external structure of these 
 buds; thev were not protected by scale-like leaves and their position in the 
 ro.sette was not the same; thus flowers and vegetative shoots may be seen in 
 the same specimen to have developed in no particular order. The species thus 
 agrees with P. ixihi.stris L., according to the description given by Hj. Nilsson 
 (Dikotyla jordst. I.e., p. KiS).

 The fifteen sptcies collected by the expeilition represent the following 
 sections according to Kngler:= NephntphiiUinii (laud.. Hirciibis Tausch., 
 Boraphila Engl., bactyloiilcs Tausch.. TmchuphijUiim (laud., and I'orphy- 
 rion Tausch. The number of species enumerated and d'/scrilied by luigler (I.e.") 
 aggregates IGG, and many of these exhibit a geographical distribution of 
 enormous extent, throughout the northern hemisphere, and to the highest eleva- 
 tions in the mountains. 
 
 Owing to this very wide distribution the genus nadirally exhibits (pute a num- 
 ber of morphological' structures which may well be looked upon as epharmonic 
 characters. Nearly all t he species are herbs, and th(\v are generally small plants, 
 but with the flowers quite conspicuous and of delicate striu^ture; very character- 
 istic of the genus is the immense variation in leaf-outline; we have a number of 
 species that exhibit the same leaf-shaiie as various genera of other families. 
 For instance, there is a species called "acon'tifolia," and among others may be 
 mentioned "ajuqaifoli,,." "cvdu^MvJdin" "hedfracea," "hi€rnriiM:'n," '•hmrheri-

 However, some Siberian specimens which I have before me, collected near

 S. Kyallii Kngl. anil S. davurica Pall. 
 
 These are both known from .Alaska .and adjacent islands; they exhibit the 
 same haliit as the preceding species l)iit the leaf-shape is (piite distinct. 
 
 S. hieraciifolia \\ . et K. and S. nivalis L 
 
 Tli(>se are also members of this section {Boraphild) but iheir liabii is very 
 different from that of iS'. aestivalis. The rhizome is relatively short but quite 
 stout in the former, and secondary roots develop freely; the almost sessile 
 leaves are arranged in a rosette smrounding the terminal, flower-bearing stem. 
 Axillary buds sometimes develop rosettes contemporarily with the terminal, 
 and several inflorescences may appear upon the same individiud. Characteristic 
 of tluse species of Bvruphila is the enrly withering of the primary root. 
 
 Although quite frequent in the arctic region, S. slcUnris L. var. coinosa 
 Poir. was not found by the expedition. I mention it in connection with the 
 other s|)ecies since it is quite an interesting plant showing some struct lU'es 
 which reciu- in members of the section Nephrophylliim. TIk; typical .'^. 
 stellari.< L. has an ascending or idinost horizontal rhizome which, according to 
 the substrate, may attain quite a considorabtle lengtli; for instaricc, iii speeinif-iis 
 growing in wei moss the rhizome measures the lengtli of about IS cm. (specimens 
 from Austria) and bears small, scale-like leaves subtending stolons of the same 
 structure as the main rhizome. In these specimens the aerial leaves are so 
 remote that no rosette is formed; however, in the northern plant a rosette i

 rosettes of leaves wit'' teimiiial flowering .■ .is. When growiriR in loose, wet

 Camden bay), which bear typical Ereen leaves. Bulblefs occur also in this 
 >peciis as described and lipured by vVariiiing (I.e. ii. 211), and by Ci. I.indiiiark.* 
 
 The section Hirctdus comprises mostly Himalayan species, but one of 
 ihcse, S. Hirculus L., i.< also widely distributed throughout the northern henii.s- 
 phcrc ,tiid reaches the polar regions in both Worlds. The arctic plant is low, 
 the flowering stcm.s reaching a height of only G cm. or less; it forms small and 
 more or less compact cushions of numerous leaves, and .several flower-bearing 
 stems ire prod. iced on the san.ic individual. There is no primary root in mature 
 specimens but the profusely branched, subterranean shoots bear many filiform, 
 second.iry roots. The subterranean stem represents in these arctic specimens 
 from Bernard harbour, Ilerschel island, etc.. a horizontally creeping rhizome, 
 about 7 cm. in length, slender, but woody, den.sely covered with remnants of 
 withered leaves ami branching freely; stolons with scale-like leaves are known 
 to occur in the southern |)lant but I observetl none in the numerous arctic speci- 
 mens, which were examined. Vegetative reproduction is siantily represented by 
 the arctic plant, since the branches of the rhizome are of a solid, woody structure, 
 not jjeniitttiiig the 3ccon;'..ary rosettes to become separated from the mother-plant.

 in some specimens from near (lie -iiinmii of James' peak (13,()()0 feet). .-I'siomewhi 
 
 remarkahie structure occurs. They grew in somewhat damp soil associate 
 
 with Siirirsia, /)r//«.«, AdinvUa, etc., and the tiower-hearinR stem reached 
 
 height of aliout I.') cm., Iiearing aliout 7 flowers in a unil;iteral evme; the tlowoi 
 
 hearinir stem was very leafy and .several of the hasal leaves above the rosetl 
 
 stihteiided runners of the usual structure. The rosette was not so eonipact as i 
 
 typical specimens and, moreover, a suhterranean stem-portion, about o em. i 
 
 lenjijli, extended from the ros(>tfe to a cluster of secondary roots; this ston 
 
 portion bore some remnants of withered leaves and consisted thus of more thn 
 
 a single internode. Some isolated youii.c rosettes wiiich grew near the flowerin 
 
 specimens showed a similar eloiigtiied stem beneath the rosette-leaves, provide 
 
 with a I'orresponding system of s< . .iiuhiry roots at the lower end of the stem, j 
 
 third type of specimens, however, explained this singular structure; it con 
 
 .sisied of ;i rosette of leaves with runners, but instead of being terminated by ai 
 
 inflorescence the main shoot had continued to grow above the rosette as 
 
 vegetative shoot bearing several scattered leaves and terminated by a rosett 
 
 of .1 more open structure than in the typical plant. In other words, the alpin 
 
 S. fliifitlliin's may remain at a purely vegetative stage for .several years, but no 
 
 as a single rosette, gradually increa.sing in size, as is the ca.se in tlie .arctic speci 
 
 mens, but developing an erect, purely vegetative shoot, of which the ape 
 
 assumes the shape of a ro.sette to produce (lowers in the succeeding vear, and stil 
 
 depending on the same fascicle of secondary roots. The age of siich specimen 
 
 appeared to be not less than four years, the fact that none of the specimen 
 
 examined posses.sed a primary root iiatur.ally indicates that thev owed thei 
 
 existence to ro.settes of runners, which undoubtedly is the most common methoc 
 
 of reproduction in this species. However, capsules with ripe seeds are frcquenth 
 
 to be found in al|)ine specimens, and even in \ova Zeinbla did I succeed ir 
 
 finding fully matured capsules with seeds.

 .S'. opiiosi'lifitlia, on the oiher hand, is widely distributed throughout th( 
 northern heiiiisi)here and abounds in the polar legions. It is actually an under- 
 shrub, since the profusely ramified branches above ground are woody. The 
 long stems are mostly prostrate with th(> inlernodes more or less stretched, with 
 the leaves opposite, and developing secon<lary roots (piite freely. Kiect, but 
 very short, floral shoots are developed in the axils of the caiiline le.ave.s, .and 
 they bear only one flower, at first .■ilmost sessile, but distinctlv pedicelled when 
 fruiting. In very large, old specimens tlie posterior parts of the stem have 
 frequently died o(T: thus the root-system is confined to .secondary roots; but in 
 sm.aller, younger specimens, tlie iiriniary root may be preserved; it is slender, 
 but (piite deep, and bears .several lateral branches.

 in this form the leaves varied from Iieing dentate onlv at the base to dentate 
 along the whole margin from base to apex. This author felt inclined to con- 
 sider this intermediate form as a hybrid, inasmuch as the two species keep 
 remarkal)ly constant, even when distributed over large areas The forma

 The specimens from Port Epworth harbour represent the forma inlermciUa

 PAPILIONACEAE. 
 
 Lupinus nootkatensis Donn var. Kjellmanii Ostf. 
 
 The .sppfios is perennial with a docp, strong primary tap-root bearing 
 large rosette of leaves .surrounding a tall flower-hearing stenl, the tallest speeinn 
 measuring about 24 cm. in height, the (lowering raceme itself about S cm. : 
 fruiting specimens the large legumes are den.selv villous, and about 5 cm. 
 length. 
 
 Astragalus [Tourn.] L. 
 
 The two species of Aslragahis show a very different habit. In .1. alpine 
 the primary root persists but it is very slender; the aerial shoots are rpiite lor 
 but very slender, prostrate, and profusely branched, bearing several leaves ai 
 a terminal, long-pedunculate inflorescence. Some few secondary roots deveh 
 from the nodes, and tubercles were found on some of the lateral roots. 
 
 In .1. ahoriginortuii. on the other hand, there is a very strong and thic 
 primary root, often branched and crowned with numerous, "compact clusters 
 persisting internodcs with scale-lik» le --"s, supporting leafv shoots and flowe 
 bearing stems; root-shoots ab 
 
 As may bo seen from '■ ,Part A, Plate X). the arctic specimen 
 
 A. abortginorum differs in se^ x, spects from the prairie plant described at 
 
 figured by Hooker (Fl. bor. Am.), but Mr. Marcus .Jones, to whom specimei 
 were .sent for identification, kindly informed ine that the arctic material repr 
 sented the typical plant. 
 
 With regard to the systematic position of this species Hooker (I.e.) stat- 
 that the perfect fruit which was unknown to Dr. Richardson has now been sec 
 in abundance, and proves the species to be a I'hora, rather than an Antragahi 
 
 Phaca frigida L. 
 
 In specimens from Bernard harbour, collected in the month of August, tl 
 racemes with fruit, not fully matured, measure 1.") cm. including the pedund 
 while in bloom the stem above ground measures onlv about 8 cm. in heigh 
 The primary root is long and slender and the capillarv, lateral roots bear tube 
 cles. As in the plant from Nova Zembla, which I liave described and figure 
 (Dijmphna Expedition I.e.), the aerial .shoots develop from the axils of scale-lil 
 leaves borne upon jxrsisting basal internodcs; thus a pseudo-rhizome is ah 
 possessed by this plant.

 Characforislic of tJin species of Oxytropis collcuted on the expedition is the 
 c.iespitoso growth with iiiimcrous leaves forming conipacl ciir;hions, espeeially 
 ill 0. nigrcscens and 0. nrctohia The primary root persists; it is quite long 
 Htid relatively thick, freciiicnfly supplemented liy sccondarv roots of almost the 
 SMtne length and thickness, \umcrous aerial shoots with the very .short inlcr- 
 n.ides completely hidden liy the crowded, withered leaf-sheaths, stipules, rises 
 from the erow.i of the root, and these shoots are terminaled l)v rosettes of, [eave 
 surrounding the central flowering stem overtopping the leaves, as in 0. folioloxa, 
 0. campestris and <). liimldl; or the peduncle of the inflorescence is so short that 
 only the flowers themselves are raised, and only slightly so, above the foliage, 
 as in 0. nigrencens and O. nrctobin. The habit of t liese two' species is thus identical 
 with that of Trifolium nnnum from the alpine region of the Rockv mountains. 
 A specimen of O. nigrcscens from Camden bav consists of a comp.act cushion 
 measuring IS cm. in di."-'"ter; the largest of 0. arctobia measiiri'd 12 cm. in 
 diameter. Common to . . „• two species of Oxytrupix and the Trifolium men- 
 tioned above is the two-flowered inflorescence, while in the other species there 
 are several flowers forming a head or a short, more open i vceme. 
 
 Hedysarum Mackenzii Rich, shows the same habit as Oxylropis campeslris, 
 but the flowering steins are much taller and branched, specimens from Ber- 
 nard harbour measuring 28 em. in height; the inflorescence is racemose. 
 
 Characteristic of these arctic Papilionaceae is thus the persisting primary 
 root; in most of these the growth is caespitose owing to the profuse development 
 of aerial shoots of which the basal internodes persist and from the leaves of 
 which new shoots arise, bearing leaves and flowers, and dving down to the 
 ground at the end of the season, leaving only the lowermost part to persist 
 and rep. at the ramification in the manner of a pseudo-rhizome. 
 
 i EMPETRACEAE. 
 
 ! Empetrum nigrum L. 
 
 : Several specimens were collected on tundra, with flowers and fruit; the 
 ' branches showed the typical riowth of the species and were quite long, reaching 
 ; 30 cm. in length. ^ &. *, 
 
 ONAGRARIEAE. 
 Epilobium latifolium L. 
 
 ,, J^^ tallest flowering specimen is from Cape Harrow; it measures 20 cm. in 
 iniM^rht, and several stems are developed from the woodv, thick, primary root- 
 las to the size of the flowers, the dried petals measuie 2. 2 cm. in length and 
 about 1 cm. in width. The leaves are lance(jlate, quite long, and relatively 
 narrow. In specimens from Wollaston land the flowering stems are much 
 f^hoiter, only !» cm. in length, and the leaves are short but very broad, oval in 
 loufline. While thus the primary root persi.sts .and develops as a strong vertical 
 Iroot, the basal subterranean stem-portions persist also and increase in thickness- 
 lUjion these buds become developed which give rise to the aerial, floral shoots; 
 |tlius we have in this plant a pseudo-rhizome with the primary root persisting and 
 fiirreasing quite considerably in thickness. Among the numerous specimens 
 |coll(;cted there was no indicatio;. of reproduction by means of root-shoots. 
 
 |E. angustifulium L. 
 
 ; , The Fire-weed is .so widely distributed in the arctic regions that it is even 
 .rircunipolar, but it is nowhere as abundant in the polar regions as farther south, 
 throughout the entire northern hemisphere. And farther south it is especially

 abundant in clearings and newly hurried lands. It is also called Wiilow-hoi 
 (in accdiuit (if the seeds lieariiiK ii t>if' "f '•'">? liairs thniujjli the help of \vhi( 
 the plant is readily disseminated over areas of jj;reat extent. However, tl 
 species possesses also another means iiy which its dispersal is effected, namel; 
 by the long horizontal roots developing root-shoots; these roots with liU( 
 may ()ersi.st for many years in the soil in a dormant state waiting for the oppo 
 tunity favourable to their farther development. And this opportunity is tl 
 cutting down or btuiiing of the forest. This is a fact so well known that it 
 hardly worth mentioning but. among the many reports that have been givf 
 about the sudden atid abundant appearance of the species, one might be (•it( 
 here which is cpiite interesting. M'-. I. \V. Cliickering ' writes: "In northwestei 
 Maine, on a tract of land of some 4,000 acres, over which lumbering operatioi 
 had been carried on some years ago, leaving a tangled mass of limbs and unde 
 brush a fire broke out .lune Sth and swept over this entire tract, lasting for tw 
 weeks, burning with such fury that it was almost impossible for the stage 1 
 travel along th(> road. .\ new vegetation began to start in three weeks after tl 
 fire, aiul the whole region of 4,000 acres was covered with Epilobium anjiu.st 
 folium as far as the eye could reach, over hill and valley, ridge and interval w! 
 one mass of colour from the Fire-weed." Tliis sudden and so abundant appca 
 ance of the plant must necessarily have been caused by the rapid developmet 
 of root-shoots, which thus were in the soil in the state of buds waiting for tl 
 opportunity. From the writings of Irmisch ^ we have learned about this plai 
 that it often reaches, the flowering stage in , iie first year. But, of course, tl 
 vegetation mentioned by .Mr. ("hickering could not possibly owe its appearanc 
 to seeds, three weeks after the tire. Rut Irmisch describes al.so the root-systeii 
 and this author made the interesting observation that the primary as well i 
 the secondary roots of the young seedling develop buds freely which sometimi 
 give rise to n(>w plants in the succeeding year. The wide distribuiion in tl 
 north of the sjjecies evidently depends on its diss-'iiiination by the wi..d; i 
 persistence, on the other hand, it owes to the development -ot-.shoots.

 about 1 i cm. in height.

 group of sessile rosettes. The rosette dies off after the first flowering, becomii 
 replaced by the secondary rosettes. The root-system is thus iworly represent( 
 and secondary roots are very scarce; when such develop, they proceed, one 
 two together, from the nodi of the stolons. There are thus apparently two typ 
 of shoots in this plant, viz.: the stolons with stretched internodos, and the ax 
 of the rosette, consisting of extremely short internodes with crowded leave 
 However, as a matter of fact, it is the same shoot, an axis of the same ordc 
 which thus becomes modified in structure according to its function, to d velc 
 in the manner of a horizontally creeping stolon, with the uppermost inte. od 
 becoming shortened so as to produce a rosette with a terminal inflorescence. 
 
 Primula borealis Duby. 
 
 Kjellman,' who has offered so many and most excellent contributions ' 
 the knowledge of the life-history of arctic plants, describes the over-winterii 
 buds of Primula nivalis. 
 
 In this species the over-wintering bud consists of several fleshy, scale-lil 
 leaves surrounding a series of very small leaves which in the following seasc 
 will develop into green assimilating leaves; in the centre of the bud an inflore 
 cence is already formed, and thin struettirc is to he observed at the commene 
 ment of the winter. The material of P. borealis Duby collected on the expeditic 
 contains numerous specimens with an old withered scape from the year previou

 as well as a scape of the yoar of collection, bearing nii umbel of flouers<. In the 
 axil of one of the innermost leaves of the rosette the bud to winter over is already 
 visible; thus these two arctic species show the sainc method of hibernation. 
 Furthermore, in both species the rhizome is vertical iiut extremely short, and 
 there is no trace of the primary root; the root system consists of several long 
 secondary roots developed from the basal internodes of the subterranean stem 
 or rliizome. 
 
 Uodecatheon frigidum ("ham. et 8chl. 
 
 -As in the I'rimiihte described eliove, there is an over-wintering bud situated 
 in the axil of one of the innermost leaves of the rosette, and of the yniw structure. 
 But Dodecatheon possesses a very distinct, well developed rhi/..me which is 
 horizontally creeping, quite thick, and reaching a length of up to 4..') cm. 
 Numerous long, fleshy, sparingly branched, secondary roots develop from the 
 lower face of the rhizome. 
 
 Douglasia Lindl. 
 
 According to Benthain and Hooker only four species are known, three being 
 natives of this continent, the fourth of the European Alps, generally called 
 Arctia viialiana Gaud. The genus belongs to the section Primvleae, and its 
 nearest ally is Androsucr. Gray (Synopt. Fl. I.e.), describes four species from 
 this country: D. nivalis Lindl., D. arcticn Hook , D. laevigata Gr., and I), montana 
 Gr. Of these, D. nivalin is known only from near the sources of the Columbia 
 at an elevation of 12,000 feet (Douglas), while D. arctica has been found on the 
 arctic seashore between the Mackenzie and Coppermine rivers (^lichardion). 
 and Red mountain, Yukon valley (M. W. Gorman, 1899); since then it has bten 
 reported from King point, on the Arctic coast, Lat. N. ()9'' 6', Long. W 137° 
 40', by the Gjoa expedition, and from between Herschel island and the '- „.kenzie 
 river delta by L O. Stringer. 
 
 I), arctica forms small compact cushions of erect or ascending woody stems, 
 densely covered with the appressed linear leaves and terminated by the flowers 
 which are arranged in a small umbel. None of the specimens examined had the 
 root-sj'stem preserved. 
 
 GENTIANACEAE. 
 
 Gentiana arctophila Griseb. and G. propinqua Richards. 
 
 They both are annuals and of exactly the same habit, viz.: a small rosette 
 of opposite leaves, a central, terminal, flower-bearing stem with one or two 
 pairs of opposite leaves subtending single flowers, and furthermore, one or two 
 pairs of one-flowered peduncles much shorter than the main stem, developing 
 from the axils of the innermost pairs of leaves of the rosette. They resemble 
 each other very much but may, neverthi loss, be readily distinguished by means 
 of the structure of the corolla which, according to (Jrisebach,' shows the follow- 
 ing characters: "Corollae 4, rarius 5-fidae coeruleae lobis ovato-lanceolatis 
 acutninatis cuspidatis setula coronatis et margine hinc setulosis tubo obconieo 
 basi angusto fere 2-plo brevioribus in G. propinn^ia,"— while, "corollae 4 fidae 
 coeruleae lobis triangulari-ovatis basi superincumbent ibus acutis cuspidatis 
 sctiila coronatis margine nudis tubo sensim ampliato basi lata 3-plo brevioribus 
 in a. nrrtnphila." 
 
 Most of the specimens are very small; the height of G. arctophila averages 
 from 6 to 7 cm., and from only 2 to cm. in the other.

 ohsciveil in the s|)ecimens from Mat hurst inlei ; in (Jreenland liolli types of 
 tlowcrs occur, ;ind in a larne series of specimens from .Amur most of the flowers 
 were pentameroiis; pentamerous flowers are also characteristic of the plant 
 from ('olor.ado. With regard to the plant from the Iliid.son hay region, some 
 small individuals from Fort (leorne have only lerrameroiis flowers while others 
 r'f normal size have all the flowers pentamerous; in very tall specimens from 
 Alherta the flowers are constantly pentamerous. The calvx-lohes vary con- 
 sidcralily in letiKth as may he .seen from the Htjures ( Fi)j. 0:t>,'!S,«, 11, 12 and \:i): 
 for instance in some specimens, collected urowinn together (Fins. 12-i:{), the 
 lohes may he longer than the corolla, or considerahly -horter th.an this, uiit in 
 these doviafiiiK forms no approach to the floral structure of /'. cnrinthutcn can 
 he detected. 
 
 Those two species are strictly annual and of low stature; the tallest speci- 
 mens of P. rotata measures 10 cm. in height, while /■*. cnrinthlaca does not reach 
 more than frotn 2 to 3 cm.

 Densely caespitose, forminti large cushions of a diameter up to IS cm. 
 The primary root persists; it is deep, woody, and branches very little; the llower-

 of small leaves at the apex, surrounding the single, almost sessile, relatively 
 large flowers. The plant thus represents an undershrul).

 bearing several shoots at the crown. These shoots are slender, and their a 
 terranean part bears small, scale-like leaves, while toward apex small rose 
 of green leaves appear, surrounding the flowering stems. As the main, i c 
 primary, root is wrinkled, indicating that it is contractile, the crown of the r 
 becomes gradually pulled deeper and deeper down in the ground, at the sa 
 time as the .subterranean parts of the stems increase in length. In young sp 
 mens the subterranean stems are thus much shorter, sometimes barely visii 
 the crown of th(> root being close to tiie surface of the ground. 
 
 COMPOSITAE. 
 Erigeron grandiflorus Hook. 
 
 A robust species, the heads measuring 4 cm. in width, borne on simi 
 leaty stems, about 12 cm. in height. A large rosette of leaves is develo] 
 from the short, thick, a.scending, subterranean stem portion, and the primi 
 root IS deep, but rather slender; similar long secondary roots develop from 
 subterranean internodes. In large specimens several subterranean stei 
 terminated by leafy rosettes, were developed from the crown of the sa 
 root. A corresponding structure recurs in E. compositus Pursh, but in t 
 species the subterranean stems are more numerous; thus the rosettes fo 
 cushion.s of considerable width. 
 
 E. uniflorus L. 
 
 In well developed specimens the habit may varj from densely caespito 
 i.e. with a rosette of leaves borne upon a verv short, erect, subterranean ste 
 bearing numerous strong, secondary roots, to a more open growth, the si 
 terranean stem being horizontally creeping, measuring ribout 7 cm. in leng 
 and terminated by a few aerial shoots with only a few basal leaves, ^rost of t 
 species belong to the variety pulcheUus Fr. 
 
 E. alpinus L. 
 
 Only a single, but well developed specimen of this, on this continent so ve 
 rare species, was found at Port Epworth. As pointed out by Lange (Consp. ] 
 Ciroonl.), It may be readily distinguished from E. xmiflorus L. by "Periclii 
 pihs non vel obsolete articulatis, floribus femincis exterioribus ligulatis, interio 
 bus ol)li(iue tubulosis." 
 
 Concerninir the habit of the plant, this differs also to some extent from th 
 of the precedinti species. The basal leaves form a compact rosette, with numero 
 strong secondary roots; from this rf)sette nine erect flowering sterns were dcvi 
 coed, ail simple, and attaining a height of about 16 cm. 
 
 Antennaria alpina (L.) R. Br. 
 
 Only a few specimens were collected and tliev represent the variety 
 which the leaves are hairy on i)otli faces. Lange ' lias called this variety cam 
 cens, and it has been found in Greenland, Scandinavia, and in the borearregio 
 of this continent, besides in the alpine region of the Rocky mountains, in Colorac 
 for instance.

 The material from Hernard harbour shows an ascending, creeping rhizome 
 with numerous long, slender, unbranehed roots; the foliage forms dense rosettes 
 but so closely crowded that the leaves, as described, are mostly erect. The 
 snow-white tomentum on both faces of the leaves renders the' species very 
 distinct from A. nlpina and its allies. 
 
 Matricaria inodora I., var. grandiflora (Hook.) Ostf. 
 
 This is the variety which Huprecht • has described under the name 
 phaeocephala. It is the arctic representative of M. inodora, and while the 
 typical, southern plant is annual or biennial, the arctic form is perennial. The 
 : specimen from Herschol island measures about 23 cm. in height, and only a few 
 * specimens bore two heads on the same stem. The subterranean stem-portion is 
 J erect, but very short, densely covered with remnants of old leaves, and the root 
 I system consists of long, slender, fibrous roots. Several rosettes of green leaves 
 I may occur at the base of the aerial stem, and the habit of the plant is actually 
 s that of a perennial. 
 
 ; Chrysanthemum integrifolium Rich. 
 
 J Characteristic of this species are the short, linear leaves forming very com- 
 
 I pact rosettes; the flower bearing stems are monocephalous. The .subterranean, 
 
 J vegetative organs consist of several ascending stolons arising from a commori

 imich m length, averaging about 6 cm. in the latter species. According to the

 By Reichenbach Xardosniia has been reduced to a mere .section of Petuaite 
 and so it is accepted al.so by Benthain and Hooker. Among the species of tli 
 section Xardosmia, \. glacialis Ledeb. and A", (hnelini DC. have the l)asi 
 leaves developed almost contemporarily with the flowers, while in the othe 
 species as well as in Petasites s.s. the inflorescence appears earlier than th 
 leaves. 
 
 Froni a morphological viewpoint the genus Petasites offers several points c 
 interest, for instance with regard to the structure of the rhizome; in this respec 
 several species have been discus.sed by Hjalmar N'ilsson," viz.: /'. iilija (L ) Gaertn 
 P. spuria (Retz.) Reich., and P. officinalis Mocnch. 
 
 In these the rhizomes bear series of meii.branaceous, sheathing leave^^ 
 destitute of i)lades, and some with blades and long petioles. In P. frigida th 
 following structures have been observed. In a fruiting specimen from Ilersche 
 island, collected in August, the horizontally creeping rhizome bears a tall (2 
 em.) flower-bearing .stem, and at the base of this the rhizome continues us ; 
 liorizontally creeping stolon, consisting of six internodes. The first three leave 
 are scale-like, but after these follow two long-])etiole(l, green leaves, situatei 
 very close together, while the leaves of the apical portion of the rhizome are mereb 
 scale-hke. A fragment of a stolon from the .sanie localilv (Fig. ^S; 2) illustrate 
 this structure. In another si)ecimcii (Fig. 1) from the .■^oii'lii coast of Coronalioi 
 gulf, collected m July, thi> rhizome bears a tall, fiower-l.earing ftein at the ha.si 
 of which I wo young, green leaves aie situated. The apical ]H,nu,u of the rhizomi 
 l)ears four scal<>-like leaves, of which the fo.emost partiv ><urrouiids two ver\ 
 young green leaves. In other words, the rhizome is undoiihtedlv a monopodiun 
 with the Hower-beanng stem axillary, as shown in figure 1. Moreover, it woiih 
 app<'ar as if the green leaves (Fig. 2) represent a veiv short vegetative i)ran<-h 
 developed in (he axil of a scale-like leaf. ( 'oiicertiing the root-svstein. secondarv

 \o doubt the Altai mountains constitute a most important centre of 
 tribution and mnuy species were developed there which succeeded in reat 
 the northeastern corner of Asia, and from there extendinR to arctic Am 
 ana Oreenland A similar important centre was undoubtedly located in 
 JMiropean Alps, known to be so very rich in alpine species, many beinc end 
 to these mountains. Furthermore, the Hocky mountains bear evidence of ha 
 been the actual centre of an old, alpine vegetation, of which several sr)eeieH 
 entered the arctic region and nov constitute a large element, a truly Amei 
 one, of the polar flora. 
 
 These data are consequently of great importance to the solvinc of 
 problem regarding the probable location of the centres of developnu-nt 
 aistril)iition of our arctic plants. 
 
 However such singular distribution of plants is more readilv obser 
 When we de;d with the alpine vegetation, comparing this with the arctic, 
 instance, in ( olorado the alpine vegetation illustrates the fact at once, that 
 composed of six elements: <ircumpolar types; arctic, but not circump. 
 norltiern but not arctic tyf)es; northern types, endemic to North Amei 
 andtinaly there are some southern types common to both Worlds, or end( 
 to North America. J his heterogeneous composition naturally induces u 
 attempt some sort of tribulation of the complete geographical di.stributioi 
 the arctic species. But it is by no means an easy task to mark .lown a nun 
 of species credited to the various districts in the north and south. And 
 diflieulty presents itse f from the indisputable fact that many species repoi 
 from the arctic have also been recorded from th.. south, but un.ler other na. 
 1 think especially of such species as have originated in the arctic recion 
 were forced to migrate to the south during the glacial epoch; some of these v 
 left on the southern mountain summits, while the others returned to ti 
 northern homes when the ice receded. Such species as were left on tlie.se me 
 tains thus represent remnants of a glacial flora, and naturallv the chance in 
 dimatologie conditions has, sometimes, resulted in their appearance uii 
 disguised forms which not infrequently pass for different species 
 
 Xevertheless, if such tabulation lie not absolutely correct," it will alw 
 give us some idea of the distribution, in a general way, of a number of spe 
 which are still recognized as identical, northern as well as southern types 
 
 Having thus reached to obtain a view of the geographical distribution, 
 a pme e ement proves a surprisingly large representation in the north, and espi 
 a ly in the arctic region. And besides that, this same vegetation, at least a num 
 of the alpine species, show also a more or less extensive distributiim thrmi 
 out the southern mountainous regions of both Worlds. Among these spec 
 w-e incet thu.s with some that exteiul to the arctic region, and others of wh 
 the distribution may extend far to the north, but without reaching the ar( 
 countries Of these the latter frequently show a vast distribution through, 
 the northern hemisph(-re and, moreover, a distribution which may pr< 
 exceedingly scattered. The occurrence may be so scattered, indeed, that 
 are at a loss to appreciate how the species ever reached such stations, so rem, 
 from each other. ' 
 
 .\nd as will be demonstrated in the subsequent pages, the species whicl 
 have m view, are not only .such as occur on the summits of the higher mountai 
 v^ry remote froni each other but also such as are more or less lowland plan 
 With respect to the origin of some of the.se, I have suggested the probability

 Some few- examples may he cited to illustrate the probability of a sini 
 centre, viz.: Carex fesiiva, and of evidently several: C. atrala and C. alvn 
 Having studied several .species of the genus Carex from this particular point 
 view, we might consider for instance C. fesiiva. This species is arctic, but neitli

 tloiii of the island miKlit Imvo been onrichc.l by aiiothor spi-cics. A still irioic 
 strikintt instaiicf of a luni aotiiiR as a carrier of seeds was observed several years 
 ago by Mr. Hryaii on Marcus Island, where lie found no fewer than 40 seeds of 
 a tree Of the madder family adheriiip to the feathers of a shearwater. These and 
 other similar facts show how tlie flora of oceanic islands may be transported by 
 birds from island to island or from conlinenis to distant shores." 
 
 Furthermore, that resident birds, jis for instance the partridge, may well 
 transport manv seeds from one |)lacc to another, has been pointeil out by Dar- 
 win.' 
 
 \\'ilh regard to other factors of dispersion, water for instance, we know, so 
 far, too little about the possibility of s(eils retaining their vitality during |)ro- 
 lonjied immersion in salt water. The transport by means of ice may takf- place, 
 as pointed out by Simmons, when the (pieslion merely <leals with narrow chan- 
 nels or fjords, but, nevertheless, more indirectly so, since the wind becomes a 
 more or less necessary, additional factor for carryinn the sc<ii> to the shore. 
 
 Hov.cver, even if we have reached no decisive coiiclusi(.n as to the means 
 by which the mi(iration was effected, nor by what roads it took place, we do 
 know that the plants exist there, that aictic ami sdpine speci<'s do occur in the 
 polar rcfjions, and (piite a numbei of these furthermore in thi mountains farther 
 south. It seems e\eii plausible to suppose that the mountains harbour a larger 
 nundier of arctic renmants than has re.iliy lieen accounteil for, becau.si' the 
 arctic siM'cies in the mountains as well as the alpine species in the arctic rejjion 
 may have submitted to a more or less pronounced iindilication in structure dm 
 to the chaiiRe of conditions. Such inodilieation, in external structurn especially, 
 ma.v, as stated above, have resulted in the res|)ective species appeariii(i in dis- 
 >tiiise, and beinf.'; mistakeii lor separate s|)ecies. In this w.iy botanical nianu.als. 
 comprising floras of mountainous regions, are sometimes crowdeil with >u|)- 
 posed new species which actually are simi)ly "loditied forms or varieties produced 
 iiy change of environment, especially- climate and soil. ( "onseciuently, wheii 
 <leal'-:g with plants scattered over large areas, we must consider whether lhe.\ 
 ri'preseiit analogous types or mere forms. Aitiini.sid. Aitlimioria, Driilxi. and 
 several other genera have recently furnished an almost untold number of su|)- 
 posed new species, regardless of the natural modification to be sought in "geo- 
 graphical distribution." 
 
 Returning to the circumpolar species, these iiaving been so admirably des- 
 cribed and their distribution disrussed by some of the ablest botanists, the 
 danger of (MMors in their det.'rminalion is but slight, even if more recently sonu 
 authors liavc ventured •(> make changes as a rule wholly unwarranted. 
 
 H.aving enumerated the circumpolar species, <'ollected l)y the expeiliiioi' 
 we shall now <itfer a few data regarding their occurreiM'e in other region-, more 
 over, some points will be discussed relatisc to the southern, the .MliLiie eleineti'

 centre of these speeirs, their reiitre of development mikI of disti ibiition. For this 
 purpose I have especially seleeted s\i(li species as are not circunipolar, atul of 
 which the distrihutioti in the south is well exeinplitied. 
 
 In hcKinninu with the Flerithiplivta, the species collected by the expedition 
 arc too few to (jive us any idea of the icprcseiitiition of this Kroup of plants in 
 the arctic reijion. Therefore, in the ac<'()nipanyinK lal)le I Table 21, I have 
 enumerated all the species known from our arctic shore, including the islainls of 
 the archipelaRO, and from (Jrcenlaiid; however, in view of the fact that several 
 Bpecies reported from Greenland have not, so far, been found on om- arctic

 Canadian Arctic Expedition, 191S-IS 
 
 tree A'as fivp fort in circiiinforpnce three feet above the ground. Dr. Anderson 
 fnrtherinoro states that none of these trees were very high, but were mostly 
 straight-grained, and not twisted spirally as are most of the spruce in this 
 region. 
 
 These northern groves of spruce have been mentioned already by the earliest 
 expeditions which visited the lower Coppermine river, notablv bv Samuel 
 Hearne (17()9-1772), Captain John Franklin (1S19-1822), and Dr. johii Richard- 
 son (182.5-1827). In his "Arctic Searching-Expediiion. 1848-1849," Dr. .John 
 Richardson gives an interesting description of the spruce, as he found it above 
 "Bloody Falls" 0!i the Coppermine river, which rn.ay be quoted as follows: 
 "(Crossing overland from west of the mouth of Coppermine river to above 
 Bloody Falls) we encamped on the 7th September on coming to a clump of 
 stunted white spruce .... In the existence of many scattered stumps of 
 decayed spruce tir trees, and the total absence of young plants one might be led 
 to infer that of late years the climate had deteriorated and that the country 
 was no longer capable of supporting trees so near the .sea coast as it had formerly 
 done. The largest trees in the clump in which we bivouacked had a circumfer- 
 ence of 37 inches at the height of four feet from the ground. Its annual layers 
 were very numerous and fine, and indicated centuries of growth, but I was 
 
 unable to reckon them. This place lies in Lat. 67° 22' X Oneci:cum- 
 
 stance which came under my observation, and has been cursorily alluded to, is 
 the existence of very ancient stumps of trees, either solitarily or grouped in various 
 places of the barren grounds, seemingly the vestiges of the forest which had 
 spread more widely over the country some centuries ago than in the present 
 day. . . . . On the sheltered banks of rivers, even in the barren grounds, 
 clumps of living trees occasionally occur, but the stumps I speak of stand often 
 on the exposed side of a hill, and indicate a deterioration of the climate, however 
 that may have been produced. We saw no young firs growing up in such situa- 
 tions to leave similar vestiges in a future age Within the Arctic circle 
 
 it (the white spruce) seldom exceeds 40 or 50 feet in height, though in ravines 
 where it is well sheltered, and has a suitable soil it attains twice that altitude. 
 Its age in these high latitudes exceeds 400 years before it shows signs of decay." 
 Similar observations were made by Mr. Frits Johansen, who has published an 
 interesting arcticle on "The Forest's Losing Fight in Arctic Canada,"' in which 
 the author calls attent.on to the scarcity of very young spruce trees in this 
 northern limit of their growth. Mr. Johansen attributes this to the intense cold 
 and the sweeping winds in the winter killing off most of the small seedlings which 
 may have developed during the summer. This explanation seems well founded 
 by the fact that even the small and stunted trees were found to be about 
 half a century old, while the largest trees would reach an age of almost 
 500 years. Furthermore, Mr. Johansen made the interesting ob.servation that 
 forest insects are principally responsible for the killing of the trees or tree parts 
 in the lower Coppermine river, a fact which has, so far, escaped the attention of 
 the various explorers who have visited the region from time to time. As a matter 
 of fact, the very isolation and exposure of the individual trees here makes them 
 an ea.sy mark for attacks by forest insects, which by living under the bark are 
 less influenced by the shortness of the summer season. 
 
 As to the occurrence of spruce on the arctic side of the mountains west of 
 the Mackenzie delta. Dr. II. M. Anderson writes: "Information which I have 
 obtained from natives and reliable white hunters and prospectors agrees that 
 west of the Mackenzie delta there are spruce trees ,ii Babbage river (back of 
 Kay point, Y.T.), and on Firth river (thf- so-called 'Herschel Island river,' on 
 both sides of the International Boundary), but none on rivers west of these.

 With respect to the general distribution of Picea canadensis, Sargent ' 
 gives this as follows: "The White Spruce inhabits the banks of streams and lakes 
 and the borders of swamps, in rich moist alluvial soil, ocean cliffs, and less 
 commonly at the north rocky slopes of low hills; it ranges from the shores of 
 Ungava bay in Labrador westward to those of Hudson bav, and from the mouth 
 of Seal river not far to the north of Cape Churchill, it "is scattered along the 
 northern frontier of the forest nearly to the shores of the Arctic Sea, and, crossing 
 the continental divide, reaches Bering Strait in m° 44' north latitude. South- 
 ward It extends down the Atlantic coast to southern Maine, growing often close 
 to the shore, and to northern New Hampshire, Vermont, New York, Northern 
 Michigan and Minnesota and the Black Hills of Dakota, and through the 
 interior of Alaska and along the Rocky Mountains to northern Montana." 
 
 The accompanying photographs were taken by Dr. Anderson and Mr. 
 Johansen and give an excellent idea of the growth of the spruce in the far north. 
 
 Among the 20 species of Gramineae, enumerated on the geographical 
 table (Table 1), ten are circumpolar: Hicrochloe alpinu, Alopecurus Arclagrosti.s, 
 Trisetum, Catabrosa, Poa arctica, Dupontia, Festiica ovina and F. rnbra. and 
 finally Arctophila. With the exception of Dupontia, Arctophila, and Catabrosa, all 
 the others have also been reported from the Altai mountains; Trisetum, Poa arctica, 
 and the two species of Fesluca are known also from the Himalayas. With regard 
 to their occurrence in the Alps and Pyrenees, only Trisetum and the two species 
 ot Festuca have been reported from these mountains. In the Rocky mountains 
 south of the arctic region we have only four of these represented, namely, 
 Trisetum, f ' hrosa, Poa, and Festuca ovina; this seems .somewhat peculiar 
 •since they ave been found on the American coast of Bering strait, and with 
 
 the only exception of Dupontia and Alopecurus, thev have also been reported 
 from the Asiatic coast. However, Dupontia, Arctophila, and Arctagrostis are 
 almost exclusively confined to the arctic regions, and the presence of Arcta- 
 grostis in the Altai mountains may indicate that the genus reached these 
 mountains during the glacial epoch and remained there. Besides these circum- 
 polar species, all of which undoubtedly originated in the arctic regions, the fol- 
 lowing may also have had their centre located in the north, viz. : Hierochloe pauci- 
 flora, Calamagrostis, Elymus, Poa glauca, P. abbreiiata, and the species ofGlyceria.

 Iceland, and Norway, sopiiis to support tlic theory, proposed l)y Natliorst, tliiil 
 the American eh-nieiit in the Eiiropeiin nioinitains may have reached these l)y 
 way of (Ireeniand durinj; the glacial epoch.

 Pyienees, Caucasus, Altai, hesides i e Rocky mountains, as far south as (Colorado, 
 eannot t)ossil)ly have ac()uired such wide, hut more or less disconnected ran^e, 
 from one single centre, located in the south, or in the north either. 
 
 Carex raginata is in the table marked clown for: islands of the arctic Ameri- 
 can archipelago, arctic Scandinavia, ••irclic Rus.sia, Iceland, Alps and Pyrenees, 
 and both coasts of Bering strait. The species is, moreover, widelv distributee! 
 in the mountains of Central lOurope; it occurs also in West and East Siberia, in 
 the Amur district, and in northern Japan. Several varieties h.ave been describe. 1. 
 viz.: distracta Norman from Finmark, pnuciflora (W'ahlenb.) Ands. from East 
 Siberia, "Lena," f,>Mt7/m Aschs. et Oraeb. from the Baltic provinces, Pctemii 
 from Kamtchatka, altocaulis Dew. from Labrador to British Columbia, the 
 northern Atlantic States, and al.so Michigan .-nd Minnesota. It would thus 
 appear as if the centre of distribution of this species may l)e located south of 
 the arctic region; the occurrence of certain varieties in the south speaks also in 
 favour of this supposition. 
 
 Furthermore, Carcx vaginala is a member of the Grex Cenchrocurpae,^ the 
 species of which are indeed southern types; onlv a verv few have reached the 
 polar regions, viz.: C. bicolor All., C. livida Will'd., and'C. vmjinuta. However, 
 the distribution with-n the arctic region of these species is very limited. 
 
 According to these data, the arctic Gramineae and Cypcraceae do exhibit 
 a much wider distribution in the north than in the south, with only a very few 
 exceptions, i\a.mdy: Festiica altiiica, Elynn, Carex mginata, C. rupestris, a'nd C. 
 scirpoidea. And, furthermore, there are several members of these families which, 
 according to our present knowledge, are endemic to the arctic regions, viz.: 
 Hierochloe pauciflora, Poa abbreviata, Arctophila, Dupontia, Glyceria, Elijmu.s, 
 Carex stans,C. subspathacea, C. reducta, and C. compacta; in all 12 species (Gli/ceriu 
 with 3), which are confined to these regions and must naturally have developed 
 there. Arctophila and Dupontia are both well marked, and indeed, quite char- 
 acteristic genera, and none of their species are known except from the arctic 
 regions. Furthermore, Hierochloe pauciflora and Poa abbreviata are both excellent 
 species, and may well be looked upon as genuine arctic tvpes, i.e. "types" with 
 regard to their morphological structure and geographicaf distribution. 
 
 The species of Glyceria are al.so interesting from this point of view; their 
 habit IS very characteristic, when compared with that of most of the other 
 species of the genus and, as has been shown in the chapter dealing with the mor- 
 phological structure of the arctic plants, G. vilfoidea shows a very singular 
 structure of the stolons, which is almost unique. But with regard to the Cyper- 
 aceae, even if Eriophvnim, at least some of the si)ecies, may have originated in 
 the arctic, the singular structure of the fruit constitutes no character which t'K 
 genus does not share with its southern representatives. And among the ('aricet^ 
 there seems to be no type especially characteristic of the arctic regions; the 
 genuine arctic species, not only those as are circumpolar, but also tlio.se a.s arc 
 confined to the polar regions, resemble their .southern allies, alpine as well as 
 lowland types. 
 
 The te.nperate regions of both Worlds are the principal ' )n.e of Juncus 
 and Luzitla: chey have developed there and acquired a hal and structure 
 which marks them wherever they occur. However, there i: also an arctic 
 element of both genera which seemingly originated in the far nortl. and of which 
 several types have entered the alpine regions in the south during the glacial 
 epoch; some,, but only a few, species arc endemic to the arctic regions.

 of tliese species corresponds well with the northern as far as .•oncerns Kurope

 30 , Dus6n), but which has not been found, so far, on the North American coast 
 With regard to the arctic Siberian element, KjeUman (I.e.) has recorded nine 
 species from the north coast, principally collected bv himself on the Vega 
 expedition. These species are: R. Chamis.wnis Schl., li' Pallasii, R. sulphureus. 
 H. nivalis, R.pygmacus, R. hyperboreus, R. affinis, R. acria, and R. lappontcus. 
 Concerning the arctic American element, this consists of six species namelv 
 R. Purshii Richards., R. Cymhdaria Pursh, R. Sahinii U. Br., R. occidental^ 
 Nutt., R. lapponicus L., and to some extent, R. affinis R. Rr. 
 
 Ranunciilus occidentalis Nutt., a near ally of R. recunatus Poir., is a native 
 of open woods and low ground in the northern Rocky mountains, from where it 
 extends to the Alaskan coast and islands, and south to the borders of California 
 The variety robustus Gray has been collected on the Alaskan islands, and on the 
 north coast. 
 
 With regard to the representation of the genus throughout the northern 
 hemisphere, the Old World element is quite distinct from the North American 
 On this continent 'iS species are enumerated in the Synoptical Flora, not includ- 
 ing 6 introduced species, and not either the genera Kumlienia, Arcteranthis, 
 Lyrtorhyncha, and Batrachium. And among these species of Ranunculus some 
 certain groups are much better represented on this continent than in Europe 
 and Asia. For instance, the section comprising R. ambigens Wats., which 
 corresponds to the Eurasian R. Flammula alliance; furthermore, the sections of 
 R. adoneus Gr., and of R. abortivm L., which do n-* seem to have any analogous 
 representations in the Old World. On the other hand, the section comprising 
 R. AispidMS Michx. IS well exeniDlified in the Old World, and more extensively 
 so than on this continent. The circumpolar species : R. hyperboreus, R. pygmaeus, 
 R. nivalis, and R. lapponicus, besides R. Pallasii, R. sulphureus, R. Sabinii, and 
 R. affinis are, as may be seen from Table 1, much more widely distributed in 
 the polar regions than farther south; some few have extended as far south as 
 the Altai mountains, and some even to the Himalayas. But their principal 
 range lies within the arctic region where they undoubtedly originated. R 
 Cymbalana does not properly belong to the arctic region, even though it has 
 reached the west coast of Greenland at a very few stations onlv; the distribution 
 of this species is mainly "sea-shore and margins of salt-ponds in the prairie 
 region of this continent; however, it has also been recorded from several stations 
 jn the Hudson bay region, and even farther north. 
 
 While thus the arctic species, with the only exception of R. Sabinii, have 
 also been recorded from the Old World, it seems somewhat strange that the 
 American alpine element of the genus is not represented; and the same is the 
 case of the Eurasian alpine element, for the few species enumerated above as 
 having found their way to the arctic region, R. auricomus, R. repens etc 
 are lovyland types, and the extension of their southern range northward is 
 evidently of a relatively recent date. 
 
 The circumpolar Papaver nudicaule is a genuine arctic type which during 
 the glacial epoch became widely distributed in the higher mountains farthtT 
 south; and although still in existence in the Altai mountains, Dovre mountain 
 in Norway, and in the Rocky mountains as far south as Colorado, there is no 
 trace of the species in the Alps or Pyrenees. It is one of the three plants which 
 have been found north of Lat. 83", Sax^fraga oppositifolia and Alopecurus alpinus 
 being the two others; it may also be mentioned that Papaver nudicaule occurs in 
 western Thibet at an elevation of 16-17,000 feet. 
 
 Among the Cruciferae we meet with types of very distinct geographical 
 distribution: ° => f

 Eutrema, una Cardamine pratensis. '

 I lilt occur in (.reeiilHiid and on this contin.nt only is oxtremelv smM: Lesmier- 
 elln, Drabn aurea, Ursperix. Arnbis HolhoeUli, ami A. Ilookeri.' 
 
 liy coniparinR the KeoRraphical distrihiition of the neims Saxifraga, we have 
 seen hat not less than 7 out of the 1.5 species collected are circumpolar; and 
 witti the only exception of S. rivularis, they are, furthermore, widelv distributed 
 farther south. KiiRler,' who has arranKe.l the species in very natural .sections, 
 attributed the followiriK K<'ographical tlistriliution to those of the species which 
 occur Within our rexion. i.e., the one explored hv the expedition. 
 
 .\ephrophyllum: Of the 19 species, representing this section, 10 occur in 
 t he mountains of Spain, south of the Pyrenees, and of these are endemic to 
 these mountains; timonR the others some few are known from the Alps 
 t aucasus, the Himalayas, eastern Siberia, the Rockv mountains, and Alaska ' 
 
 Ihe section Hirculn.s contains 11 species, 10 of which ar(> endemic to the 
 liimalayas; the eleventh species, .S. Hirculnx, shows, .-is mav he .seen from the 
 tahle an extraordinarily wide distribution throughout the northern hemisphere. 
 
 lioraphila with 2;{ species is mainly Siberian, about 16 species being charac- 
 teristic of the districts between Altai and Kamtchatka, beddes western North 
 America; some other species are more widely distributed on this continent, 
 and J of these are endemic; sev(>ral species are also known from the Himalayas 
 among which ;j en(leiiii<>. The section is, furthermore, widelv distributed in'thc 
 arctic region. 
 
 While :Ui siM'cies are attributed to the s(>ctioii Diicti/loiiles, most of these are 
 Irom hpaiii. Atlas, and the Canary islands; some few are known from the Car- 
 pathian mountains and the South American Cordilleras; a verv few species 
 occur in the Asiatic mountains, but none in the Himalayas. 
 
 VVith regard to the section Tmchyphi/llum. most of the species are 
 Himalayan, and only a very few have been reported from Altai, Kamtchatka 
 western ^orth America, and Central Europe. 
 
 Of the four species represent' ,4 the .section Porphi/rion, three are confined 
 to the mountains of Central and South Europ<-, whil.- the fourth one, S. oppositi- 
 folKi shows an enormous distribution through the northern hemisphere and is 
 besides, circumpolar. 
 
 The data regarding the distribution of the sections, of which species were 
 collected by (lie expedition, thus indicate the difficult v in locating the actual 
 centres of their distribution, whether the species originated in the north, notably 
 the arctic region, or in the .south. However, with reference to S. miliata Small 
 (.*«. vxtb)i Steph.), the very limited distribution points towards the centre having 
 been located in northeasfprn Siberia, wh(>re it is accompanied bv a near allv 
 S. sibirica. ' ' ' 
 
 S. reflexa Hook., being exclusively arctic and confined to the coast between 
 the Mackenzie and Copix-rmine rivers, must have originated there. .S'. aestivalis 
 grows on the north coast of Siberia, but is .seeminglv rare there; from there it 
 extends to Altai and Haikal, and eastward to Kamtchatka, the coast of Man- 
 churia, and St. Lawrence island. On this continent the sp(>cies has been reported 
 from Alaska, together with the very local S. Xelaoniana, as well as from the 
 Kocky mountains, as far south as Colorado, and the Cascade mountains. JJeing 
 apparently very rare in the arctic region as conipared with its distribution 
 farther south, and esp(>cially in eastern Asia, I presume the centre of both S. 
 aesliraliK and S. Xelxoiriana must have been in northeastern Asia. 
 
 With respctt to S. broncfndlis. the very wide distribution of this species in 
 the arctic region of Hii.ssia and Sil)eria, and being so very rare on this continent, 
 absent from Greenland and the arctic American archipelago, seems to indicate 
 that its geographical centre may have been located in Siberia, but not ncccssarilx 
 within the arctic reffinn since ttsc species seems to he <iMite vvell distributed

 Canailiun Arctic Eiimlilion, t91.i-lS 
 
 
 S. y/<rcWM.'! originatrd in tlic arctic regions. For nowhcro wliom the siM-cirs 
 occurs docs It Pxlubit any pronounced tcn.icncy to vary, rx.T," with n.fcard to 
 tlic fohaRe: oblonRo-lanroolata," "lincaria," "spathulata," etc. By ><on.(. 
 authors, Lanpo, for instance (Consp. FI. firoenl.), the arctic phmt is considered 
 as representing a variety "alphn, Kngl." from the Ilin.ahivas, but the deviation 
 
 ion. the type depends merely m.on a dwarfed, more condensed growth, the 
 leaves a little broader, etc. The arctic plant resembles the alpine; it is able to 
 produce .ower.s and npen th." s.'ed even as far north as Spitsbergen, according 
 to IIess(.ln;ai. d-e.), alihougli probably not every vear. ' "" ' •* 
 
 \\ ith resjiect to N. rii iilnris and .V. cirmw, both being also widely distributed 
 tarther .south especially the latter, the..e species are well adapted to the arctic 
 ( iniale, hy d(.veloping bulblets which, in the latter, have almost entirely re- 
 placed tlie lowers; m this respect .S'. ccrniia resembles the arctic form of .S' 
 ■-irllans, ns described. The geographical centre has undoubtedly been within 
 tiie aictn- regions. I he prevalence in the north, together with the eireum- 
 polar ( nbntum. .«eems to indicate that .S'. uiralis and ,S'. hiimcilfulia are also 
 arctic tyfies and that they originated in the p<.'Hr regions. 
 
 nut with regard to S. tlirlji'ms, it seems somewhat doubtful whether an 
 arctic centre could be credited to this species. We should remember that the 
 section ;>/c/,vo/r/cs ,s decidedly southern, and N. dccipiens is, so far as we know. 
 al)out the only one which occurs in the polar regions and is circumpolar. It 
 tias however, two near allies, the distribution of which reaches far north, namely, 
 .^. hupimidis J which IS common in Iceland but more widely distributed in 
 soiittnustern Fuupe, and .s. ^v7cno^/7(,roSternb., known only from arctic and sub- 
 arctic .North America, viz.: Hudson bay region and Alaska. 
 
 As far as concerns S. dccipirns, this [)olymorphic species is best developed 
 in the n.ountains of Central Europe, but is totally absent from the A.^iatic 
 mountains. Lngier (1. c.p. 18ti) has enumerated several varieties, among which 
 
 groenlandica is credite.l to ttie arctic regions, and also to Norway, Iceland, and 
 Oreat Britain; two other varieties, "car.pitom" and "uniflora," a'rc also credited 
 to the northern regions. Bm the more evolute forms "vulgari^^" and "quinquc- 
 fida are exclusively southern. It would thus appear as if the species had 
 developed m the .south Central Europe for instance, where it is best represented 
 and best developed. \\ herever it is met with in the polar regions it is always of 
 a stunted growth and few-Ho^vered, which might indicate that it is a foreigner 
 in these regions, but haying adapted itself remarkably to the change of condi- 
 tions and having acquired .such wide distribution so as to become circumpolar. 
 Otherwise with regard to ;•.'. oppositi folia. This species being circumpolar

 extendinK northward to the aretie shore and the arehifM'hiRo, and westward to 
 Ahisl<a;.S. (ilnrialis is known oidy from the arctic seashore west of the Mackenzie 
 river; S. cullhifolin is known from the northwest j'oast, Unalaska and Sitka. 
 
 ■^''■"''•''"K >" I-<'<lei)oiir, S. filacialin and S. Hoxmi oeeur in "astern Siln-riu, 
 .S. calthifiilin in Kamtchatka. JJeside these a fourth species is enumerated by 
 Ledelxiur (Fh)r:i Koss. I.e.), S. niiemoiwiilcs \{. Mr., also from Kamtchatka. 
 l-inally, there are two species in the .\lps and l'yren<"es .S. montann (L.) SprenR., 
 aijd .S. ni>t(itts (L.) Spren^., and one in tiie Himalavas, .s. ,!i:ln Hovle (alt. 9 0(K>- 
 lo,00() ft.). 
 
 \\e have thus before us a Rcnus of (piite an extensive Ke«>Kraphical distribu- 
 tion, l)ut disconnected and .seemingly unexplainal)le. 
 
 None of the species are circumpolar; none have l)een rei^rted from arctic 
 huropo, and nevertheless, two species, one of which is vi'ry characteristic by its 
 8toIoniferous habit (.S. repl(iHK), inhabit the .\lps and Pvrenees. On the Sil)erian 
 north coast from 17:}° W. Long, to iW K. J.onf{. S. glacialifi is the onlv species 
 recorded so far (Kjellman, I.e.); the Rcnus is ab.sent from the Altai and Baikal 
 mountains which otherwise harbour so many arctic sfn-cies; in the northeastern 
 corner of Asia, however, N. liosaH. S. aiUhifolin, and S. (itumnnoidis j.re indigen- 
 ous liui between these regions and the Himalayas no speries has been recorded 
 and, as mentioned above, only one occurs in these mountains. 
 
 ()n this continent, however, the distribution is fairlv well connected, tor 
 even if .S ulaciahx and N. ralthifnlia are very rare on the northwest coast, and 
 none of them crossinfj the Mackenzie river, we have in .S'. Ronxii a species quite 
 extensively distributed in the arctic region, including the islands of the archi- 
 Fjelajjo, and extenduiK south to the alpine summits of the Rockies; furthermore, 
 .V triflorn which is- not arctic but widelv (listrii)uted from the Atlantic to the 
 lacihc slope and southwards to Colorado, following the Rockv mountains, 
 tinaily, the AllcKhenies and the White mountains are the home "of .S. radiata. 
 Hut 111 spite of this fair representation of the genus on this continent, none has 
 l)een discovered in (Ireenland. 
 
 If now the question be asked where these species, or let us sav the genus, 
 originated the answer cannot possil)ly be in the south, nor in the north alone. 
 Itie .South European elements did ceriainly not come from the north, since 
 they are endemic to these mountains; tliev must have originated there, where 
 .urthermore, they are associated with two near allies: f/«)*.7( and Dri/ax. 
 
 \\ ith refereiK'e to the arctic species, N. ghciali.s anil ^S. liiKsxii. these must 
 nave (lev(>loped in the polar regions, and of these the latter, S. l{u>i.-ii, did not 
 altogc'.ier leave the .south when the arctic flora returned for, as mentioned 
 at)oye, it is ttill in existence on the :ilpine summits of the Rockies, in Colorado 
 lor instance. ,S'. tnflora and S. cullhifnlin are evidentlv of vounger origin, both, 
 tiowcver. from a northern centre evidentlv located in Canada. Another centre 
 ot development must hav(> been in the Appalachian mountains, so far as con- 
 cerns .S. rndmto. Finally, with regard to S. vUttn. m> widelv secludeil from the 
 ottier .species, this must have originated in the Himalayas." 
 
 Con.sidering these data it .seems to be characteristic of the southern element 
 of the genus that so very few species have become <leveloped, and that the.se 
 are endemic to the .southern mountains: ,S'. elutn to the Himalayas, -S'. repfans 
 and ^. monlana to the Alps and Pyrenees and, tinallv, S. radiata to the Appal- 
 achian mountains. The reason may be that the centres are of a more recent 
 date, and therefore entirely independent of each other. And it is a point of 
 great importance, I believe, that these independently developed 
 the'ess show the typical habit of true Sieversia; the only dist 
 
 species never- 
 nction appears in

 with rcspoot to the oll.or species of whieh the habitat, as mentioned above, 
 speaks in favour of a centre farther .south. Moreover, the fact that it is as.socil 
 atea with two closely aiiied .species in soiKhcrn Europe, seems to indicate a 
 Tmerr" '"^ "^ ""^ '^''"*''" °^ (lis<ril.ulion, in Europe rather than in Asia or 
 
 In oiitlining the ncoKraphical chslribiition of Htppuris (see Table 1) I 
 might just as well quote from Hentham and H()oi<cr's great work "Gener'i 
 plant.arum, ' m which it is Riven .is follows: ".Species I vel. 2 anuarum 
 emperatanim et friKidnrum luiidp.ie, Asiae mediae et boralis, et Americae 
 boreahs et Anfnrct.cae iiicolae." And to these data mav be added that it 'is 
 circumpolar. Hippuris w-as found by Kjellman at I'itlekaj on the north coast 
 of Liberia, E.at. U,° .>'; in Grecnh.nd the typical plant is rare and confined to the 
 .southernmost part at .'d.out (iO° \. I,.; the varietv warifimn Hartm on the 
 other hand, is known from t he west coast of Greenland between tiO° and 70° X ] 
 and on the east .wist it has been reported by Dusdn from flurrv inlet (71" N 'l7 
 .Olid l)y llartz from Scoresby sound, at the .same latitude. We liave thus iri 
 HippuriH an excellent illustration of the remarkablv wide ranee exhibited' bv 
 many freshwater and even marsh species. Severaf other examples might be 
 recorded nit I sh.all confin,- myself to mention a few, for instance- Ilydrilla 
 of which the only species, a freshwater plant, is known from tropical Asia and 
 A istraha; P allisnena, common to tlie tempr-rate and warmer regions of both 
 Worlds; Hydrochans, commcm to Knropv and Asia: luihalus, from the .seashore 
 ot Ceylon to the .seashore of Austr.ilia; Rammciihi.^ nutans C. A. Mev from 
 Colorado (Twin Lakes near Eeadville ), known also from .Siberia (Ahai and 
 Baikal); hnally, Caltha natan. Pall., from easfrn Siberia. Haikal mountains 
 Jemsei, furthermore on this continent: Minnesota, and, in the Northwes 
 Territory: Peace river tributaries near Fort St. ,Iohn, Methy portage, at about 
 n/ x\. 1.. How these and many other aquatic plants were dispersed so as to 
 acquire such enormous distribution has been explained bv Darwin (Oricin of 
 bpecies), the means of dispersal being notablv wading birds. However as has 
 been mentioned in tlie preceding pages, migratory birds mav well be capable 
 of dispersing seeds or shoots of aquatic plants from one point to another, thus 
 covering areas of no smal extent even during a single .season, but from what we 
 have learned about thes,- birds, when migrating, in the stricter sense of the word 
 dispersal, from one coniinent to another, does not seem probable 
 
 Ihipleurum amcnvanum C. et H. is credited to the American coast of Bering 
 strait where It was hrst found by Chamisso and Eschscholtz ".ad promontoriuni 
 Espenberg, furthermore, to Alberta, Montana, Idaho, an.l Wvoming; accord- 
 ing to Macoun's ( ataloguc (I.e.) it has been collected .at Eort". Selkirk Yukon 
 river, at the foo hill« of the Rocky mountains (Eat. 49°). and cast of the Mac- 
 kenzie river (Richardson). E<"debour (Elor., Hossi,.,) considered the specie.s Jo'be

 The genus contains about 60 well marked species but 90 have been des- 
 cribed, according to Bentham and Hooker. There are about 8 perennial species 
 among which i/. ranunculoides inhabits the Alps of Switzerland, about 16 the 
 Pyrenees; and several are also reported from temperate Asia and the tropical

 Ledebour enumerates .several others from Altai. Baikal, and D.-^vurJa It'would

 It IS absent from Asia. And it would seem just as strange if the genus had

 Canadian Arctic Expedition, 191S-18 
 
 distributed farther north, but the genus, nevertheless, has reaehed the eastern 
 part of Siberia and Manchuria from where it extends to Alaska, until it reaches 
 the northern and middle regions of this continent where, from the Atlantic to 
 the Pacific, the genus exhibits its widest distribution. 
 
 It woiild seem quite natural to consider the wooded belts of the middle 
 parts of this continent to represent a geographical centre of Monescs; possibly 
 the genus migrated from there to eastern Siberia, Manchuria, and the Altai 
 mountains, rather than vice versa. 
 
 Absent from arctic Siberia but recorded from all the other districts enumer- 
 ated on the table (Table 6), Pyrola minor thus shows the widest distribution of 
 all the members of Pyrolaceae. On this continent the habitat is given as "cold 
 woods, Labrador, Wliite Mountains of New Hampshire, Rocky Mountains from 
 New Mexico and northward to the Barren country from Lat. G4° to the Arctic 
 IMands." Nowhere is it alpine, however, and in the temperate parts of both 
 Worlds it is associated with the same species of I'yrola, and, not infrequentlj', 
 also with Moneses. 
 
 It seems barely possible to suppose that the species was formerly repre- 
 sented in arctic Siberia, thus having been a member of the circumpolar flora, 
 even if it is known to occur very near Lat. 70° on the west coast of (ireenland 
 (Hartz), and on Melville peninsula (Parry). It is, however, a rare plant in the 
 arctic region and, being flecidedly a sylvan type, the geographical centre must 
 have been located south of the polnr regions, in the wooded belts of the Old 
 World, nresumably, since it is much more abundant there than on this continent, 
 and mt., evenly distributed from north to south. Like Monrncs it is very 
 constant in habit, only one variety having been recorded, var. braiti Lge. from 
 Greenlaiid. 
 
 An almost corresponding distribution is shown by P. .si'ciindn, with exception 
 of its absence from arctic America and Kan^tchatka; in Greenland the typical 
 plant does not occur, but is replaced by the variety /ibtusata Turcz.; this variety 
 is also recorded from Terra Tschuktchorum, from Canada, the Atlantic and 
 Central United States. Like the preceding species, P. secunda is a woodland type 
 and is not known to be alpine. Besides the variety obtusata, two others have 
 been described, viz.: pumila Cham, et Schl., and dispersiflora Norm.; of these the 
 former is distributed from Labrador to Alaska; it follows the Kockies south to 
 Colorado, and has been recorded from eastern Siberia and Altai. The var. 
 dispersiflora Norm, is known only from arctic Scandinavia. Considering the 
 relatively wide distribution of the typical plant on this continent in the north 
 as well as in the south, extending to California, Colorado, and Maryland, and 
 in view of the development of two characteristic varieties, it appe:ii> as if some 
 important centr(> must have existed on this continent, presumably in the 
 wooded belts of the northern part. With regard to the Siberian distribution of 
 P. secunda. we have seen that this extends from Terra Tschuktchorum, eastern 
 Siberia to Altai, and, fu-thermore, Maximowicz has recorded it from Ea.st Man- 
 churia. But the absence of the species from the boreal regions of Siberia, exce,)t 
 in the northeastern corner, makes me believe that the Asiatic element of the 
 species has really originated on the American continent. 
 
 Two important centres of distribution must undoubtedly be attributed to 
 P. chlurantha, as shown on the accompanying table (Table 6). " On this continent 
 the distribution extends from Newfoundland, Labrador, and the Maritii .e Pro- 
 vinces westward to northern British Columbia and Alaska, south to California, 
 Colorado, and Maryland. In Europe P. chloranthn ''as reached the arctic zone 
 in Finmark; it is quite generally distributed through the European continent, 
 going as far south as the Alps, the Pyrenees, and Ka.san in Russia. But so far, 
 the species has not been ob.served in Asia, and it is thus the more interesting to 
 notice that an analogous spc- 'oes exist in eastern Manchuria, namelv )'. 
 renifolia Maxim. It would cult to combine the European distribution

 Il now the (|iiestion lie asked where the arctic American species oriKinated, 
 we mJKht siinKcst that the circnnipolar s|H'cies came from the arctic regions. 
 Hut the olijection naturally will !«• made that theve, viz.: /'. Inpfmiiiin, i'. 
 Iiirsiilii,n\u\ p. siiilitini are at present hetter representeil in Silwria where, more- 
 over, they urn associateil with allied j-peeies. Ami the Silierian alliance of 
 I'nliciiliirtH corresponds Ix-ller with the circumpolar than d<M's reallv tin- North 
 American. 
 
 'I'he nenus IS w.ll repre.-enled in the Himalayas, since Hooker ( Flor.i of Mr. 
 Ind. I.e.) has creilited Xt sp<eies to these mountains; of these 2 occur al^o in 
 Altai. 2 in Haikal, while /'. lerlii-illala and /'. (kderi are, as we know, widely 
 distrihiited farther north, east, and west; the rpmaininR 29 species are endemic 
 to the lliinuluyas. 
 
 Several of the arctic sitecies reach a oon.siderabiy hi^h latitude, for instance 
 those recorded from SpitzlterRen; with regard to the Greenland sjiecies P 
 hirmita oxtend.s to l.at. 81° 7' on the west coast, and to Lat. 74" 40' on the east 
 coast (DufK'-n); fuithermore, /'. Inpponirn, P. lanaia, and /'. capilcla arc reported 
 froiii resp. Lat. 78^ 18', l.at. 79°, and J.at. 78° 18' on the west coast; P.flammea 
 reaches l.at. 74° on both coast.s. And with regard to the altitude which the 
 8r>ecios att'un in the mountains, P. sdvntica, P. Inppoiiica, and P. Ocderi ascend 
 to about 3,t)00 feet in Norway; in the Alps of Switzerland /'. vcrticillala has lj«>en 
 recorded from 9,000 feet (Heer, I.e.), and in the Himalavas most of the endemic 
 species are alpine and several reach an elevation as high as 14-lti,00() feet; P. 
 rnlictlldtu and /'. Otderi are in these mountains reported from resp. 1^,000 and 
 lOjOCMI lf'(*t. 
 
 Witii regard to di.stribution, P. vcrticillnta exhibits the widest distribution 
 esiwcLilIy southward, extendinfj to the Alp.s of Switzerland, .Altai, and the Hima- 
 layas; in the north it is ab.sont from the arctic American MrLliipclafro, (iroenland 
 Spitzbergen, and Scandinavia; thus it cannot be considered circumpolar. The 
 present distribution of the species in the north, and at the .same time its occur- 
 rence in the Alf)s s ns to indicate the probabilitv of it iiaving had a former 
 
 more extensive distribution northward during the glacial epoch. /'. flamnwa 
 absent ficm Siberia but present in the arcti<- American archipelago, in (ireen- 
 land, Srandinavia. Hiissia, and even in Iceland and the Alps, evidentlv originated 
 111 the north and i.resumably in the arctic regions of this continent and of western 
 Europe. On tlie other hand, P. ihdin, totallv absent from North America and 
 Cireenland but extending from Kamtchatka thro-rh Siberia and Hus.sia to 
 Scandinavia and present in Altai and tlie Himalavas, may have had the centre 
 located ill the north of the Eurasian continent since it is not at present a .southern 
 species either in hurope or in Asia. P. mphnmoidcs is a genuine American 
 type with .•several close allies in the Kocky mountains, and the Asiatic element 
 of this species came undoubtedly from this continent where it is widely di.s- 
 tributed south of the arctic region, from Labra.lor throughout the continent to 
 Bering strait. While P. urdu-a is known onlv from .'irctic America Siberia 
 and Kamtchatka, P. lanata occurs also in Greeiilami, Spitzbergcn, .■m'd Nova 
 Zembla. but they both evidently originated from the polar regions of these two 
 continents, .Vmerica or Siberia; the .same mav be th . - -

 have thus in these species of ('(ii)ipiniiilii. represented in the arctic 
 
 rcRions a coniimnjrliiifi- of types amoiin which ( . ,iiiijli,ni occupies a soniewli;it 
 ISO ated position: consideriiifr the wide distribution on this continent where it is 
 cither arctic or alpine, it seems probable that C. uiiitl-ini is a mi'inber of the old 
 Kliicial vegetation, and that the centre of its distribution was located in the 
 arctic regions ot this continent. 'I'he occurrence of this s|)oeie.s in Scandinavia 
 IS one ol the .several cases which Xathor.st has mentioned as demonstiatinjc the 
 prob:il,|e road ol migration of the American element across ( Ireenland to Ic.'land 
 and Scandinavia. With '-(.jj,.,,-,! to CamiMiiulu roliimlifolio. this is not an arctic; 
 !.vi)c. JudKinn from its predomin.ant distribution southward, but the species 
 is evidently one of tho.se that acc(mipaiiied the arctic flora on its retreat to the

 firinnlandia, Herl.," which tofrether with the varietv „M>cn l.tre. thus represents 
 the sj)eci.'s m the far north 
 
 As regards C. Ii,sii>air/Mi on the northwest coast, this is undoiibi.Mllv of 
 Siberian origin, as indicated by DeCandoHe, and the same is the case of C.

 now cMsls. It may he nientioned th.al Xalhorst is in favour of the siiiipositioii 
 that the arclic \egelation. at least to some cxteiu, originated in the lowlands of 
 the polar regions, l.ut that the greater portion w,is originallv alpine. 'I

 Witii the iiiorphological sirucliire .so remarkahlv unif(jrm in the arctic

 Asia: lerra J schnkt Chorum and Kamtchatka. Then with regard to .Unne.'ies 
 his show^s the same distribution as P. ,ecunda but is ab.sent from Caucasus.' 
 Jinally, P rhloruntha is alxsent from t.>n of the eighteen districts enumerated 
 on t tie table, namely: our north coast Greenli.nd, llus.sia, Siberia and 
 the p' 'eiees" "* '■'''"■'^'"^"^•■'' '" ^'"'"J'*' ""O"' I'''">"ark south to the Alps .and 
 
 We have thus four species of a remarkably wide distribution in both Worlds 
 Ncvertheless, the Pyrolac.-ae are be.st re])re.se:ited on this continent, the home of 
 thn-e species oi (h,mai,hiln besides of Piirolaclliptica, P. picta, P. chimaphil- 
 wd,x, and /'. aphjlla. an.l the foliage of th.- last three species resembles that of 
 (lumnplula more than that of P,,r.>h; in Europ.^ there is a .somewhat isolated 
 type: /. m,-,Un. It is mten.sting to i.otiee that wliile P. chlorantha is absent 
 from .VsiaMaximowici: ' .hs.oveied a near ally of it, /'. renifolin, in coniferous 
 woods in the Amur distri.'t where, moreover. P. secnndn, P. rotundifoUa, Mon- 
 i'so-1. and ( Inind/ifiild uwhclliitd were collected. 
 
 It would thus ap[)ear a.< if the centre of the Pyrola.'eae might have been 
 ..cated on this contiiMM.t, r.ather than in the Old World, inasmuch as the Mono- 
 tropeae. the nearest allied family, are also best represented here, with seven 
 in'rum'Ie""" •'"'' '^'""'''''' "'' ''''''''' ■^^'"""''"1"' '■' ""' ""'y K'^"us occurring also 
 
 However, when we bear in mind that P. minor and tvpical P. rotund,fol,a 
 are mu.'Ii more abundant in Kun.pe than on this continent, it might be more 
 oiiect not to include them in the American element, I mean the element 
 which i)resiimably originated on this continent. 
 
 With respect to P. rhloruntha it .seems difficult to combine its distribiii,„n 
 iti L.irop.- with that on this continent and, as st,'.ted above, it is absent from ill 
 
 of Asia. 1 he occurrence of Chimaphila uuibeUata in Europe causes al.so e 
 
 difficulty but Its distribution m Asia. Altai for instanc.-. mav point towards a 
 lormer, much wider distribution, at present disconnected. 
 
 Taking all points into consideration it .seems a most difficult task to treaf 
 the distribution of this singular littl.- family, almost exclusivelv confine.l to the 
 temperate regions of M,th Worlds, and being mostlv svlvan types. For whether 
 their centre of aistiibiition, or let us .say development, be placed on this con- 
 tinent or in Europe, the question will necessarilv arise how these little plant- 
 have remained so unchiingei on both continents when, as stated bv Darwin - 
 I ^'.*J'r^f"1*^ * "^ "?.''■ '"'"^ !)ioductions of the temperate regions of the New 
 and Old ^^orlds, we hnd very few identical species, but we find in every great 
 class many forms, wlmh some naturalists .ank as geographical races, -.nd others 
 as distinct species; and a host of closely allied or representative forms which 
 are ranked by all naturalists as specifically distinct." " 
 
 With respect to the Pyrolaceae some certain "geographical races" have 
 become developed, notably of Chimnphila xmbellata, Pyrola secunda, and P 
 roundifoha, but, nevertheless, the typical species are represented in both Worlds. 
 Otherwise with r spect to the plants with which they are associated.

 the geniw Sirrcrsiii at several points remote from each other, and although the 
 genus is both rctic and alpine, the origin of thi; gi'ri;n may be interpreted in 
 the SMine lighi as I'ljrola, Munesex, and ChimnphiUt. 
 
 We have seen that iS'. yladalin, S. I{oK>"i, S. calthifolin, S. radintn, and >S. 
 trifiora are natives of this continent, and that N. fjlacialis and .S. Rosxii occur 
 also in eastern Siberia, S. nilthifolia in Kamtchatka; furthermore, that S. 
 rrplatia and .s'. monUtna are endemic to the Alps and Pyrenees, ,S. eliita to the 
 Himalayas; that »S'. aticfiionoidcs is a natixc cf Kamtchatka and Japan, S. 
 kuiatiirica Heg. et Schmalli. of Turkestan. 
 
 Ill other words, there must have been nio'e than one centre from where the 
 genus developed, two on this continent, viz.: the arctic coast; a .second one in 
 the Appalachian mountains; a third one in the Alps and Pyrenees; and a fourth 
 one in the Himalayas. The arctic element may well be connected with 'he 
 species in Kamtchatka and Japan, but the oiher species are so isolated that no 
 I'onnoction seems possible. With reference to the species themselves, the struc- 
 ture of the style, it being iointed, wholly persistent and straight, is a constant 
 charaetiT in the genus. hile the style is glabrous in .S'. liossii, it is pilose 
 
 in all the other specie.s; furmermore, the petals are erect, not spreading, and of 
 a redilish colour in .V. trijlora, but in all the others the petals are yellow and 
 spreading. The memlievs of Sierersia thus slinw the same sectional structures as 
 dcum with regard to the flowers, viz.: Caryophyllastrum: petals white, greenish- 
 yellow to golden-yellow, spreading; Caryophyllata: petals purplish, erect. 
 
 The nearest ally o! Sieversia is ^Vitm, repre.senteu on tnis continent by eight 
 species, four of which are endemic. Among these (/. macro phylluin extends to 
 Kamtchatka. (!. Mriclnm is, on the other hand, widely (listributed through 
 iSiberia to Central Russia, including Caucasus and the Altai mountain.s. G. 
 rivalc, though not infrequent especially throughout the northern parts of this 
 continent, is more generally distributed in IJuope and Siberia; (/. urbanum has 
 become established at Cambridge, Mass. 
 
 In the Alps and Pyrenees Geum is represented by (r. rivale, G. urbanum, G. 
 pyrenakxim Willd.,and G. ni/lvaticum Pourr. ; of these (r. urbanum is the only 
 species recorded from the Himalaj^as. 
 
 Another near ally of Sievcrsia is Dryas which, as we have seen, occupies 
 much the same territory as the northern species of Sieversia, besides occurring in 
 the Alps and the Pyrenees. 
 
 Sieversia is thus an excellent e.xample of a genus having developed at 
 immensely remote stations, giving rise to species very do.scly related to each 
 other, yet absolutely distinct. The rule that the most natural genera, or those 
 genera in which the species are most closely related to each other, are generally 
 confined to the same country or, if they have a wide range, ttiat their range is 
 continuous,' can not be applied to Sieversia. And several corresponding instances 
 may be cited from other families. We remember the genus Pleuropoyun of which 
 there is a high-ncrthern type, P. Sabinii, and two ones endemic to California, 
 viz.: P. refractum Benth., and P. californicum Benth.; furthermore, Claylonia' 
 which is one of the most characteristic genera of North America is in Australia 
 represented by C. australasica Hook, and in New Zealand by C. cclycina 
 Colenso.

 I cannot see any ohjection to the supposition that the same species tiiay ulso 
 arise from morn than oni' sinule area. 
 
 I have mentioned these few data as a mere su)t(j<'sli<>n sii[)i>leniental to the 
 explanation f>f the siiiKular distrilmtion of some of the arctic plants as demon-
