38 VIOLACE^. 



often lacerately toothed at base, decurrent on the petiole, pubescent on l>oth 

 sides ; stipules broad-lanceolate, ciliate ; sepals oblong-lanceolate ; petals 

 obovate, entire ; lateral ones densely bearded. V. sagittata, var. ovata 

 • Torr. tf* Gr. V. primulafolia Pursh. 



Dry hills. Can. to Geor. April, May. If-.— Whole plant pubescent. Leaves 

 much narrower and more downy than in C. cucuUata. Flowers larger than those 

 of V. primulcefolia. Ovate-leaved Violet. 



7. V. villosa Walt. : leaves reniform-cordate or reniform, obtuse, crenate, 

 flat, very pubescent ; sepals oblong, auriculat% at base ; lateral and lower 

 petals bearded ; stigma deflexed ; capsule smoothish. V. barbata Mwhl. 



var. cordifolia Nutt. : leaves smooth beneath, rather acute ; sepals narrow, 

 short, smooth and scarcely produced at base. V. cordifolia Schw. V. soro- 

 ria Darlingt. 



Rocky hills. Penn. to Car. May. %. — Leaves rather thick, mostly incumbent 

 on the ground) often purplish on the under side. Scape longer than the leaves. 



Bearded Violet. 



fj- FUrwers yellow. 



8. V. rotundifolia Mich. : leaves broad-ovate or orbicular, cordate, with 

 the sinus at length closed, slightly crenate, smooth beneath ; stipules lance- 

 olate-subulate ; sepals oblong, narrow, obtuse ; lateral petals bearded ; 

 lower ones smaller, smooth ; spur very short ; stigma recurved. 



Rocky woods. Can. to Car. May. 1\.— Scape 1 — 2| inches high, smooth. 

 Flowers pale yellow, middle sizQd. Distinct from V. clandestina of Pursh. 



Bound-leaved Violet. 



•j-j-f Flowers somewhat regular, small, white. 



- 9. V. laTiceolata Linn. : leaves very smooth, narrow lanceolate, atten- 

 uated at each end, sub-serrate; sepals lanceolate, acute, smooth; petals 

 beardless, nearly equal ; spur very short ; stigma recurved, rostrate. 



Swamps. Can. to Flor. W. to Texas. April, May. %.. — Scape about as 

 long as the leaves. Flowers small, white, inodorous. The long narrow leaves 

 will sufficiently distinguish this species. One of the finest localities that I have 

 met with, is a swamp about a mile west of Albany, N. Y. Lance-leaved Violet. 



10. V. acuta Big. : leaves ovate, smooth, crenate, rather obtuse ; stipules 

 linear-subulate ; scape angular ; bracts nearly as long as the petals : sepals 

 lanceolate, acute, smooth ; petals ovate, acute, mostly smooth, lower ones 

 veined ; stigma capitate, rostrate. 



Moist grounds. Cambridge, Mass. Big. %..—A small species. Distin- 

 guished by its even and always acute petals and by its long linear bracts. 



Acute Violet. 



11. V. primulafolia Linn.: leaves smooth, oblong-ovate or lanceolate, 

 subcordate, rather obtuse, sparingly crenate ; nerves beneath and scape 

 somewhat pubescent ; sepals lanceolate ; petals obtuse ; the two lateral 

 ones a little bearded and striate ; stigma capitate, rostrate. 



Wet grounds. Mass. to Flor. W. to Ken. ; rare. April, May. %— Leaves 

 2 — 5 inches long, and an inch or more wide, about as long as the scape. Flowers 

 white, odorous, about the size of those of V. lanceolata. Bracts long. This 

 species varies in the form of its leaves from broad-cordate to lanceolate. 

 Near New Brimswick, where what I consider the V. primulafolia, is very abun- 

 dant, it certainly passes into V. lanceolata, with which species I thuik it will 

 eventually nrove identical. Dr. Bigelow suggests that F. hlanda. and V. lance-
