green or glabrate, only the young parts being at all hoary, and the leaves larger and rounder, yet apparently belong to the 
same species as Dr. Gregg’s plant, on which this genus was founded The silicles vary from four to seven lines in length, are 
oblong-elliptical, or sometimes broadly oval, with a pretty strong emargination at the apex, strongly ob-compressed, and with
