Root annual. Stem 1—2 feet high, erect, branching, with the leaves 
Very pubescent. Leaves 2 — -3 inches long, hoary and with segments va- 
riously toothed. Floivers in terminal racemes. Leaves of the Calyx oval 
erect, pubescent. Petals obovate, as long as the calyx, expanding, yel- 
lowish. Stamens longer than the germ. Style short. Stigma capitate. 
Pod short, distinctly angled, sometimes splitting at the angles as if four 
valved. Seeds many in each cell, obovate, slightly roughened. 
While looking over my specimens I have had reason to believe that we 
have another species in this country closely allied to the present, with 
leaves more finely dissected and with longer pods, but I have not materials 
to complete its character. 
Grows in sandy pastures, very common. 
Flowers March — April.
