Stem from a foot to a foot and half in height, erect or spreading, cylindrical, 
branched, branches subvirgate, simple, flexuose ; the whole covered with 
minute branched and stellate pubescence. Leaves varying from one to 
three or four inches long, linear-lanceolate, tapering at the base, the 
smaller ones subserrate or almost entire, the larger sinuato-pinnatifid ; 
both kinds rough with branched pubescence. 5 
Flowers in terminal racemes, subcorymbose at first, afterwards decidedly = 
cemose. Pedicels nearly an inch long, erecto-patent, slender, furnished 
with a linear bractea, which is inserted near the base. Calyz of four li- 
near-oblong, erect, closed leaflets, equal at the base, the back green, pu- 
bescent; the margins membranaceous or diaphanous. Corolla of four 
cruciform petals. Claws rather long and linear ; limb lanceolate, white, 
channelled in the middle above, somewhat keeled and greenish below, 
the margin pinnatifid, with three or four narrow linear segments on 
side. Stamens six, four longer and opposite, approximating i _—* _ 
still shorter than the claws of the corolla, the others opposite and 
yellow. 
At the base of the stamens are four small” green ovato-lanceolate shining 
glands. Pistil columnar, very pubescent, less so on the margins of the 
septum. Style extremely short, green, subglabrous. Stigma capitate, 
yellow, with a vertical furrow, so as to appear shortly 2-lipped. Pod 
nearly erect, linear, somewhat swollen in the middle, pubescent. Valves 
convex. The margins of the dissepiment somewhat prominent. Seeds 
eight or ten in each cell, placed in two rows. Seed-stalk rather thick, 
short. Seeds pendent, ovato-rotundate, 
itself very long and linear, is seen to be cleft’ almost down to = 
base into two equal filiform portions of a bluish-green sae ra-
