 Jersey. April-May. — Rhizoma short and thick. Leaves usually a little 

 pubescent on the upper surface, crenately toothed, often somewhat hastate

 er than the leaves. Flowers middle-sized, bright blue. Spur short and 

 very obtuse. 



8. V. villosa (Walt.): pubescent; leaves plane (appressedto the ground),

Sandy pine and oak woods, in the southern States ! March-April— 

 Leaves very pubescent but not villous, rather thick, becoming nearly glabrous 

 late in the season, variegated with purple veins, often entirely purple under- 

 neath. Flowers small, pale blue. Le Conte.— This species appears to be 

 confined to the Southern States. We have not had an opportunity of ex- 

 amining the stigma.

 crenate, nearly glabrous, the sinus closed ; petiole pubescent (flowers yellow) ; 

 stigma recurved at the apex, margined ; lateral petals bearded ; sepals ob-

 MichaiLv! 0. Labrador, Banks. May.— Rhizoma rather thick, throwing out 

 long stolons from the neck late in the season. Leaves spreading and appressed 

 to the ground, at the flowering time about an inch in length, but later in 

 the season 3-4 inches long and nearly three inches in diameter; the veins of 

 the under surface slightly pubescent. Flowers small, pale yellow: petals 

 broadly ovate, sometimes emarginate, the lateral ones with 3 brown striae ; 

 upper one small.— This may be the V. obUqua of Alton, which is described 

 as having straw-colored flowers ("petala straminea").

 the sinus rounded ; petiole glabrous ; stigma capitate, depressed, margined,
