Root whitish, of several tapering and branched fibres. Stem from about 5 or 6 

 to 12 inches high, solitary or with several shorter and slightly spreading ones 

 springing in a circle around the main stalk, terete, wavy, glaucous or purplish, 

 hispid below with while, spreading, stiff hairs, above glabrous, and in the larger 

 plants with long, slender, patent branches, which like the secondary or outer stems 

 are quite simple or very nearly so. Leaves mostly crowded into a dense radical 

 tuft, from about 1 to 2 inches in length, oblong-lanceolate, oblong-elliptical or 

 subspathulate, obtuse or slightly pointed, attenuated into a petiole, more or less 

 unevenly sinuato-deutate or nearly entire, often reddish or purplish, in dry situa- 

 tions rough all over with rigid forked hairs from tubercular bases ; stem-leaves few, 

 distant, smaller, lanceolate or linear, sessile, nearly or quite entire. Flowers 

 small, in a constantly elongating coiymb which is somewhat lax or drooping at 

 the summit. Sepals erect, oblong-elliptical, concave, not keeled, glabrous, or with 

 a few hairs at the summit, the alternate ones somewhat pointed and narrowed, the 

 others very obtuse. Petals about twice as long as the calyx, obovate, attenuated 

 into greenish yellow slender claws, the limb white, entire, at length moderately 

 spreading. Hyfoyynous glands one at the base of each stamen, small, roundish 

 oblong, those under the 2 shorter filaments much larger and more prominent than 

 the rest. Siliques on the now widely diverging pedicels, about 8 or 9 lines in 

 length, a little curved inwards and upwards, or ascending, tipped with the styles, 

 pale yellowish, reddish or purplish, glabrous, hardly ^ of a line in breadth, ancipi- 

 tal, the valves with a filiform keel or ridge running their entire length. Seeds 

 numerous, very minute, like grains of red sand in size and colour, of an ovate- 

 oblong or roundish figure, somewhat compressed and lobed by the form of the 

 cotyledons, a little rough or uneven.
