teresting region near the end of July, returning 
pres York ae way of Raleigh, Richmond, &c.; and found a 
marked change in the vegetation immediately on crossing the 
Blue Ridge. I cannot extend these remarks to the plants ob- 
served in our homeward journey, except to mention that the 
Schrankia of this part of the country, which extends to the east- 
ern slope of the Blue Ridge, is the S. angustata, Torr. & G 
at least we observed no other species. This is doubtless the ‘S. 
uncinata of DeCandolle ; but not, I think, of Willdenow. I may 
here remark, that the tetistlate-ledved species, (iS. uncinata, 
Torr. § Gr. ‘i is the Leptoglottis of DeCandolle, (Mem. Legum.) 
as I have ascertained from a fragment of the original specimen in 
the rich herbarium of Mr. Webb, which that gentleman obli- 
gingly sent me; but I find no neutral flowers or sterile filaments 
in the fhumerots specimens of this plant, from different localities, 
which Thave from time to time examined.

Hab. Rocky banks of the Scioto River, near Columbus, Ohio. 
‘Obs. The far less numerous siliques, widely spreading and 
with an upward curvature, and tipped with distinct somewhat 
clavate styles, as well as the larger flowers, will readily distin- 
guish this species from A. hirsuta, with which it has perhaps 
been confounded. It has nothing of the strict habit of that spe- 
cies. The septum of A. patens presents descending, rather 
straight, and broken lines of tubuli, which anastomose and _ pro- 
duce irreeular oblong areole, parallel with the septum. In A. 
hirsuta the areole are amorphous, on account of the very tortu- 
- OUS, anastomosing lines of tubuli. The septum of A. levigata 
has a straight central line, or raphe, extending throughout its 
whole length, with reticulations like those of the last species
