Les images suivantes ont 6t6 reproduites avec le plus grand soin. compte tenu de la condition et de la nettetd de l'exemplaire filmd, et en conformity avec les conditions du contrat de filmage. Original copies in printed paper covers are filmed beginning with the front cover and ending on the last page with a printed or illustrated impres- sion, or the back cover when appropriate. All other original copies are filmed beginning on the first page with a printed or illustrated impres- sion, and ending on the last page with a printed or illustrated impression. Les exemplaires originaux dont la couverture en papier est imprimde sont film6s en commen^ant par le premier plat et en terminant soit par la dernidre page qui comporte une empreinte d'impression ou d'iliustration, soit par la second plat, selon le cas. Tous les autres exemplaires originaux sont film^s en commandant par la premidre page qui comporte une empreinte d'impression ou d'iliustration et en terminant par la dernidre page qui comporte une telle empreinte. The last recorded frame on each microfiche shall contain the symbol — »> (meaning "CON- TINUED "), or the symbol V (meaning "END "), whichever applies. Un des symboles suivants apparaitra sur la dernidre image de cheque microfiche, selon le cas: le symbole — »> signifie "A SUIVRE", le symbols V signifie "FIN". Maps, plates, charts, etc., may be filmed at different reduction ratios. Those too large to be entirely included in one exposure are filmed beginning in the upper left hand corner, left to right and top to bottom, as many frames as required.

They are eitlu'r terrestrial, amphihious or a(|uatic. and tlu'ir veu'etative oruans may he ulal irons. ;^laucous. variouslv puhescent or .yiandular. Some species are annual, others are perennial i>y means of larj;e I'oots, creepinji- stems or rootstocks. The roots ai'e varialile in si/.e. sometimes slendei' and fihrous. often \i\v>xv. fusiform and woody. In dry clay soil the development is usually restricti'd, while in .sand they ofte'i elon.tiati' to a remarkahle de.urei'. The suh,y;enus Bis- torta furni.shes two kinds of Meshy rootstocks; the one is liulhdike and the other more or less elon.uated, either creepin.n' or horizontal. Tlii' te.xtun' of the tissues of the stems varies from herhaceous to wood or riii>|iicU(Misly iici'vcil and rarely tlircc-rililicd. and in one or two instances it lias two lateral ini|»i'essions parallel with the mitlrih.

The sti|)uK's are of mnisual form and characteristic. They are uniteil so that they form a sheath which sui'rounds the stem for a izreater or less distance aliove a mule. 'I'hese ocreae are either cylindric oi' funnelfoi'in : the former usually hori- zontally truncate at thesununit and the latter ohli(|Ue or two-])arte(l. Thesununits may he either nake(l or variously fringed with liristlcs. and in two suhucnera a sin'ejidini;'. <'ollar-like rim is found. 'I'he ocrc.ac are either ,ulahrous or strijiose. sometimes with smooth or ciliate rihs and I'arely with a I'in.u' of more or less retie.xed hairs around the hase.

The llowcrs are apetalous. liut tiic calyx is often highly colored and its segments petaloid. it is always persistent, and is usnally accrescent aftci- the flowering stage, so that it invests the achciie. ( ilands arc often present in its tissues. It !< generally live- cleft or Hve-|)arted. although we tind it in many cases varying from four to si.\-cleft or parted. The segments are nearly cijual or the outer oni-s larger and often develcp keels or coii-picuous wings which invest tlie h'uit. I'rom three to inne stamens are present in the flower: five or eight, however, arc the prevailing numhcrs; they are variously in- .scrtc(l on tile hase of the caly.x. sometimes accompanicil liy a corresponding nuinlici' of nectaries. The filaments range from filiform to suhulate or even liottle-shape: they arc persistent and sometimes altei'iiafe with small scales, and t!ie olilong or ovoid anthers are attacliease. in my opinion this is an erroneous way of interpri-ting the morphology. 'Die ovary In oiie-celled, hears Imt one ovule, and finally produces a typical achene. So it is more logical to consider the style as simple aiid more or less cleft or parted. Tiie cases in which di\ision to the liase takes j)lace are comparatively few. We sjiould theri'fori' interpret the state of the styUi as two or tlu'ce cleft or parted, as the case may he. The ovary develops into a lenticular oi' ti'lipietrous achene. if the stvle-segments are two the fruit will l)e lenticular; if three, triiiuctrous. 1 have found a state approach- ing a tetragonous fruit, hut havt' never iu'i'u aide to detect a fourth .stvle-segnient.

THE GENERAL ANATOMY. The stems under considei'ation are composed of three cylinders which are derived from the three cell-layers of the endtryonic or mcristematic sta.ii'e. The lirst, that arising;' from {\\v
  • idermal cells are present. These ai'e stomata and liichomes. The t'oi'iner were not plentil'ul in any of the examples sludieil, hut a greater or less numiier are devehiped on the younger pails. .\s regards the latter, we lind lidth non-glandular and glandidar trichonies: the former. howcNcr. pivddininate, and as with the stomata. tlu' ti'ichomes are characteristic of the Vdunger parts uf tiu* epidei'mis. although in a few eases they do e.xist e\en mi the oldesl portions. In .-onie cases the iion-glandidar trichonies appear as conical unicelhilar hairs, sometimes de- pressed, someliiues elongated. luU always with a l>liint ape.\. Then there are long hristle-like hairs, also of one cell, hut with a long attenuated ape.x. In otlu'r cases we find trichonies similar to the last in all respects save their heiiig multicellul.ar. .\s a linal modilication, in two >cctioiis we hnd simjile ilace as pith.
