38 DICOTYLEDONOUS PLANTS. 



Le Conte, and those of the Northern and Middle States have been no 

 less faithfully examined by Dr. Torrey. See Sill. Jour. vol. \. Ann. 

 of the New York Lye. vol. ii. Torrey' s Flora, vol. i. 



* Stemless. 

 t Flowers blue. 



1. V. pedata Linn. : leaves pedate, often nearly smooth, from 57 

 parted ; segments linear-lanceolate, entire or somewhat toothed ; stip- 

 ules radical, pectinately lacerate ; petals beardless, entire, rounded at the 

 extremity ; stigma large, compressed, obliquely truncate and perforate 

 at the apex. V. digitata Pursh. 



HAB. Rocky hills. From lat. 53 N. to Geor. W. to Miss. May. 

 Ii. Scaves 3 5 inches high, several from the same root. 

 Flowers large, pale blue. 



2. V. palmata Linn : leaves more or less pubescent,- reniform-cor- 

 date, palmate, or hastate-lobed ; lobes very various, the intermediate 

 one always larger ; stipules lanceolate, subciliate ; lateral petals 

 densely bearded towards the base ; stigma capitate, recurved, margin- 

 ed, rostrate. 



HAB. Swamps and low grounds. Can. to Car. May. If. Scape 

 about as long as the leaves. Flowers middle-sized. This species 

 ' varies greatly in the form of its leaves, and in some specimens 

 they are so slightly divided, as to induce me to concur in the 

 opinion expressed by Dr. Bigelow that, it is only a variety of 

 / . cuculldta. 



3. T. cucuUata Ait. : smoothish ; leaves cordate, cucullate at base, 

 dentate-serrate, veined ; stipules small, linear, ciliate ; flower oblique ; 

 lower and lateral petals rigidly bearded ; upper one smooth ; spur very 

 short, rounded. V.papUwnacea Pursh. V. affinis Le Conte. V. obliqua 

 Ait. Pursh. Torr. V. sororia Pursh. 



HAB. Wet meadows. Common throughout Can. and the U. S. 

 April, May. H- This species varies considerably in the form 

 of its leaves, and in the degree of pubescence. The same indi- 

 vidual, indeed, undergoes changes during the season. A specimen 

 in the herbarium of my brother, Dr. T. R. Beck, labelled by the 

 late Dr. Muhlenburg V. obliqua f is certainly identical with this 

 species. 



4. V. sagittate Ait. : leaves pubescent on the upper surface, oblong, 

 acute, cordate, sagittate, often hastate at base, serrate or crenate-den- 

 tate ; petals oblong, ovate, all except the lower one bearded. V. den- 

 data Pursh. 



b. cmarginata Nutt. : leaves almost triangular, lacerately toothed 



at the base ; petals emarginate or bi-dentate. V. cmarginata Le 



Conte. 

 HAB. Fields. Can. to Car. May. Ij.. Leaves quite variable. 



Flowers middle-sized, purple. Var. b. is found in the sandy 



fields of New-Jersey.
