Perennial by very short rootstocks, scaposc, almost glabrous or sparingly grandular-pilose above. Leaves basal ; blades thiii- nish (drying very thin), more or less obliquely oval or ovate, 2-7 cm. long, rounded at apex, undulate, abruptly or gradually nar- rowed at ba.se, ciliatc, sometimes .slightly pilose on both surfaces : petioles slightly shorter than the blades or longer, broadly winged : -scapes erect, slender, 1.5-3 dm. tall, loosely-paniculate-coiym- bose : calyx glabrous or glabrate ; tube broadly turbinate, nearly I mm. high ; segments oblong or ovate-oblong, slightly longer than the tube, obtuse or acutish, gland-tipped : corolla white, 5 mm. broad ; petals broadly oval or suborbicular, 2 mm. long, rounded or notched at apex, sessile or nearly so, 5-7-nerved : ovaries united to calyx-tube, surrounded by a conspicuous lobed disk : follicles short and stout, 4 mm. high, united to each other to about the edge of disk : .seeds dark red, 0.3 mm. long. On hillsides, Napa Valley, California. Collected by J. M. Bigelow (Whipple's Expedition) and George Thurber, no. 496. A species of lax habit, resembling Saxifraga clayUmiacfolia more closely than any other member of the subgenus Micmnthcs. It differs from S. daytoniacfolia by its broadly oval or suborbicular 5-7-nerved petals. Saxifraga Van-Bruntiae. Perennial, bright green, minutely glandular-pilose or glabrate below. Stems tufted, 2-7 cm. long, simple, or sometimes corym- bosely branched above, leafy to the top : leaves alternate ; blades linear, 4-8 mm. long, leathery, blunt, with a thick apex, .sessile, turning black at the base of the plants : calyx glabrate in age ; tube broadly turbinate ; segments oblong or ovate-oblong, obtuse' longer than the tube, spreading : petals yellow, oblong, about 4 mm. long, obtuse, firm, more or less crisped, much longer than the calyx-segments : stamens 10, filaments filiform. The original specimens of this hitherto undescribed Saxifraga were collected by Mr. and Mrs. Cornelius Van Brunt during the (316) ifi -U^" 317 Small: North American Plants p:i.st scasc^n on tlic summit of Sulphur Mountain near Banff, British Columbia. Tiie species is related to Saxifraga scrpyllifolia and S. ihrysixntJia ; the habit suggests those species but the stems are copiousl)' leafy to the top and the leaves are narrower. The petals are smaller, of a much less brilliant yellow and oblong or ovate-oblong instead of oval-orbicular or obovate as th y arc in the two related species. Galpinsia Toumfa-i. Perennial from a shrubby base, slender, bright green, puberulcnt. Stems branching near the base ; branches erect or ascending, wire- like, 1-3 dm. long, usually .simi)le above, leafy, pale when young: leaves numerous, sometimes clustered in axils ; blades linear- .spatulate to linear, 1-2 cm. long, acute, entire, with midrib promi- nent beneath, lower ones short -petioled, upper sessile: spikes few-flowered, leafy -bracted : calices very minutely pubescent ; tube .slender, 3-5 cm. long; segments about 1-5 cm. long, their free tips 5-6 mm. long : corolla yellow ; petals orbicular-obovate, 1.5 cm. long, undulate: anthers linear, as long as the filaments : capsules linear-prismatic, 2 cm. long. Arizona: Chincahua Mountains, July 25, 1894, J. W. Tou- rney, no. 197. Fort Huachuca, August, 1892, T. K. Wilcox. The species just described is related to Galpinsia larhocgii, but is of a much more slender build. There are minor characters in the foliage and habit, but one of the more crucial points of difference lies in the calyx, where we find the free tips of the segments 5-6 mm. in length. LiMONIUM LIMBATUM. Perennial, bluish green or glaucescent. Leaves basal ; blades leathery, spatulate or oblong-spatulate, O.5-1.5 dm. long, obtuse or notched at the apex, prominently nerved beneath m drying ; petioles shorter than the blades or rarely longer, margined: scapes erect, solitary or several together, corymbosely branched ; branches zigzag, ascending ; spikes in dense terminal corymbs : bracts suborbicular or sometimes orbicular-oval, obtuse, often eroded at the apex, hyaline-margined : calyx trumpet-shaped with a flaring limb, nearly 4 mm. long ; tube hirsute ; segments broadly deltoid, apiculate : corollas bright blue. In alkaline soil, Texas and New Mexico. As far as I can learn there has been no attempt heretofore to lear Banff, British 7 scrfiylUfolia and 3Ut the stems arc narrower.

An examination of considerable material both from the Texas and the Californian districts disclo.ses the fact that there have been two perfectly distinct species con- fused under the old IJinoniiim Calif ornUiim. As in the case of all the species of the genus the two under consideration resemble each other in habit. The diagnostic characters are contrasted below : Limonium Califoniiaiin. Calyx narrowly funnelform ; tube glabrous ; segments erect or nearly so, rounded and mucronulatc. Limonium limbatum. Calyx trumpet-shaped ; tube hirsute ; segments more or less spreading, broadly deltoid. The following specimens belong here : Wright, no. 1435 ; Woodhouse, Zuni Mts., N. M., Aug., 1851 ; Wooton, no. 172. Andkosace 01 eeusa. Annual, acaulescent, more or less pubescent. Leaves ba.sal ; blades oblanceolatc to .spatulate or nearly linear, 1-4 cm. long,' obtuse or acute, sharply serrate above the middle or sparingly toothed near apex only, sessile or with short winged jietioles : scapes erect and spreading, often diffusely branched at base, 5-10 cm. long or shorter : bracts lanceolate : pedicels filiform, very vari- able in length, often 1-8 cm. long in the same cluster : calyx cam panulate to turbinate-campanulate, 3-3.5 nmi. high; segments triangular, acute, ciliate, about yi „,s long as the s-ridged tube ; corolla white or pink, included, sometimes equalling the tips of the calyx-segments, 3-3.5 mm. broad; segments oblong, obtuse or retuse at apex, about as long as the tube : filaments shorter than the anthers : capsules subglobose, about 3 mm. in diameter. In rocky soil, western Arctic America to the *J;>kotas, New Mexico and Arizona. Spring and summer. For some inexplicable reason the species here desciibed as new has always been associated with Androsace scptcntrionalis with which it has not even a habital resemblance. Andrusacc scptcn- trionalis is a plant with strict, conspicuously elongated scapes which are surmounted by umbel-like clusters of pedicels of nearly equal length, whereas Androsace diffusa, has comparatively short, more or less diffusely spreading scapes, while the pedicels of the clusters are exceedingly variable in length. A more tangibU tit 819 Smai.i. : North Amkkican Plants character exists in the corolla. In Andi-osacc scptiiitnoiialis this orj^'an conspicuously surpasses its calyx while in the newly de- scribed species it is shorter than its calyx or barely cciuals it. Aniirosace suuuMiiELLATA (A. Nelson). Androsacc .si-f^tciitrionalis subinnbdlata A. Nelson, Ikili. \V>'om. l-'.xp. St. 28 : 149. 1.S96. Annual, diminutive, sparin^jly pubescent. Leaves basal ; blades thick, oblong', 2-8 mm. long, obtuse, entire, .sessile: .scapes 1-5 mm. long, or wanting : bracts ovate-lanceolate or lanceolate, pedi- cels .solitary or several together, 5-10 mm. long: calyx nearly glabrous, turbinate-campanulate, 2.5 mm. high ; segments triangu- lar, acute, slightly .shorter than the 5-ridged tube: corolla white or pink, 2.5-3 mm. broad, surpassing the calyx ; segments oblong, obtuse, or retuse at the apex, shorter than the tube ; filaments much shorter than the anthers : capsule globose-pyriform, about 2 mm. thick. On hillsides, near summit of Union Peak, Wyoming. Summer. In order to treat this genus consistently, we should recognize the above as a species. On the one hand Androsacc siilmiiibcllata is related to Andi-osacc diffusa : this species it resembles in habit and foliage, but it is more diminutive in all its parts. On the other hand it is related to Androsacc scptcntrionalis in having the corolla cxserted beyond the calyx. Pri.mula serra. Perennial, glabrous or nearly so, deep green. Leaves basal, 5-10 cm. long; blades narrowly oblong or spatulate, much longer than the broadly winged petioles, rather regularly dentate, acute or apiculate : scapes erect. 1-2 dm. tall, solitary or several together : bracts scarious, ovate-lanceolate, acuminate, often mi- nutely pubescent: pedicels 1-3 cm. long, glabrous in age : caUces 6-7 mm. long ; tube campanulate ; segments lanceolate, granular- ciliate, acuminate, as long as the tube or shorter : corollas lilac- purple ; tube as long as the calices or somewhat longer ; seg- ments suboi-bicular or obovate -orbicular, notched at apex, 7 8 mm. long, destitute of apiculations. Primula scrra resembles Primula Rusbyi in habit, but both the foliage and the inflorescence furnish characters for distinguishing the two species.

The original specimens were collected by Mr. I'ringie on damp ledges, Santa Rita Mountains, Arizona, at an altitude of Sooo feet, on July 25, 1 884. Pkimui..\ TENL'I.S. Perennial, glabrous, bright green. Leaves basal, 0.5-1.5 cm. long ; blades oblong, oval or suborbicular, unilulate or toothed, obtu.se or acutish, much shorter than the slender petioles : scapes erect, wire-like, 5-10 cm. tall, solitary : bracts linear-subulate, 1-5 mm. long: calices 3-5 mm. high, tubes turbinate, segments narrowly lanceolate to narrowly linear, longer than the tube, acute : cor- ollas pink, 4-5 mm. broad; tubes surpassing the calices, 4 mm long, notched at the apex. In moist places, Pastolic, Alaska. A delicate species related to Primula iwrcalis, but much more slender ; easily distinguished by its flimsy leaves, .shorter pedicels turbinate calyx-tubes and narrow calyx-segments. The corolla tube is further exserted than in Primula borealis and the more delicate lobes less deeply notched. The original specimens were collected by W. H. Dall, on June 25, 1 87 1, or 1872. aii » lfa^.iKWj g .l .- MWi^^Jii- ^ j ' i .'.ijlMli i i'lJi t LLJL.l *' ^ ^ Notes and Descrintions of North American Plants, tl II V jnllN K. Smm \l I. I.

In lov ground, Ohio to Missouri, south to Alabama and Louisiana. Summer and fall. For many years ]'cnioiiia i:^igdiitca or ]'. a/lissiiiia has been an aggregate. The campestrian plant that has been known under both of those names is very distinct from the Carolinian and Floridian plant to which both the above cited names were originally applied. The campestrian plant may easily be separated from the south- eastern species by the lower involucres with rounded bases and their proportionately broader appressed and compactly arranged bracts. The involucres of the related species are narrowed at the base and have narrower loosely spreading bracts. The following cited .specimens belong here : Mi.s.soL-Ri : Jackson County, Jhtxli, no. 230.

Stems erect, 6-9 dm. tall, sim|)le or sparingly branched : leaves various ; lower with linear blades 1-2 dm. long, upper narrowly linear and much shorter, not ciliate near the base : heads short-pedunclcd or nearly sessile, not densely crowded : involucres becoming narrowly turbinate, 7-9 mm. high : bracts lanceolate to oblong-lanceolate, acuminate, cil- iolatc, rigid : pappus plumose : achenes clo.sely pubescent. On prairies, Louisiana. Summer. This species has heretofore been included in Lacinaria acidota, with which it has little or nothing in common, and it may be sep- arated by its fewer leaves and much smaller heads which are dis- po.sed in elongated interrupted sj)ikes. The bracts of the involucre are much shorter than those of L. acidota and have less elongated tips. The .species is founded on Hale's no. 334. Lacinaria platylepis Perennial, bright green. Stems erect, 8-9 dm. tall, simple, glabrate below, pubescent with white hairs above : leaves not very numerous, narrowly linear, 2-10 cm. long, or longer at the base of the stem, glabrous or nearly so : heads rather approximate, sessile, surpassing the subtending bracts : involucres cylindric- campanulate, 7-9 mm. long ; outer bracts often ovate, acute, inner larger and broader, broadest above the middle, rounded at the apex, ciliolate: pappus not plumo.se, pale. In sandy soil, Louisiana. Plants belonging here have been referred to Lacinaria acidota. although none of the several characters warrant such a disposition, The fewer and shorter leaves, the elongated more or less inter- rupted spikes and smaller heads and involucres with their broad rounded inner bracts, are some of the characters that separate Lacinaria platylepis from L. acidota. The pappus too is not plu- mose. The original specimens were collected in Louisiana by Dr. Hale. I (•/' rg-Tizsmfi -'y g; r.- r" '~t!~r-
