4. S. viridijlora (Nutt. rass.) : " erect, glabrous ; leaves cuneate-obovate, 

 acute, entire ; the radical ones with a few runcinate teeth towards the base ; 

 petals linear, and, as well as the calyx, herbaceous. 



" Bare shelving hills on Ham's Fork of the Colorado of the West, and in 

 other parts of the Rocky Mountains, towards the sources of Lewis's River; 

 also on the head waters of the Platte. July- Aug.— Root very stout and cy- 

 lindrical, penetrating deeply into the earth ; the taste bitter and nauseous. 

 Stem simple, 3-4 feet high. Radical leaves clustered, about a span long, oc- 

 casionally almost pinnatifid at the base ; cauline ones entire, rapidly dimin- 

 ishing in size upward, so that the superior part of the stem is naked. Ra- 

 ceme very long (sometimes 2 feet in length), crowded with flowers. Calyx 

 and corolla greenish-yellow, and not showy. Sepals long and linear. Petals 

 linear ; the lamina scarcely longer than the claw. Anthers very long and 

 linear. Immature fruit smooth ; the pedicel about half an inch long : stipe 

 about an inch in length, nearly as long as the silique." Nutt.

 very slender, longer than the lamina. Stamens somewhat equal. Glands 6 

 at the base of the stamens.— Annual glabrous plants. Leaves entire. Flow- 

 ers and siliques in umbelliform racemes, purple or white : siliques pendulous,

East Florida, Mr. Ware; Middle Florida, Dr. Chapman .'—Stem 1-3 

 feet or more in height, fastigiately branched above. Lower leaves not seen ; 

 cauline i an inch to an inch in length, rather acute. Racemes scarcely half 

 an inch long ; the flowers much crowded and almost verticiUate, showy. 

 Pedicels spreading, and at length recurved, very slender. Calyx nearly equal 

 at the base: sepals purpUsh, narrow, a little dilated upward. Petals rather 

 pale purple : limb nearly orbicular, undulate ; claw one-third longer than the 

 limb, glandularly roughened towards the base. Stamens much exserted; 

 the filaments capillary and glabrous : anthers linear-oblong. Ovary linear : 

 stigma sessile. Stipe of the fruit nearly capillary, purplish, about three- 

 fourths of an inch long; siliques U inch long and less than a line in width, 

 somewhat acute. Seeds (immature) oblong, in a single series : funiculi slen- 

 der, free. 



2. W. cuneifolia (Nutt.) : leaves nearly sessile, rather thick, oblong, ob- 

 tuse, attenuate at the base ; siliques with the valves somewhat convex. — Nutt. !
