finally much elongated. Petals about three times the length of the 
sepals. Pod 6—8-seeded, almost two-horned by the projecting upper 
angles of the valves, the breadth (about 34 lines) nearly twice as 
great as the length. Fructiferous pedicels 4—5 lines long. 
2. C. longipes (sp. mov.); foliolis spathulato-obovatis obtusis vel 
retusis integerrimis vel margine serrulato-scabris; bracteis superiori- 
bus simplicibus ; ovario stylum bis superante stipite pluries breviore ; 
capsula retusa subbicorni stipite subduplo breviore.— Valley near 
San Pablo, Chihuahua, and near San Francisco, San Luis Potosi, 
Mexico, Dr. Gregg. Collected in flower only, April 29th, and in 
both flower and fruit, Dec. 28th. 
Differs from the preceding in the considerably larger and less con- 
spicuously mucronate leaves, the remarkably long stipe, and the con- 
spicuous style; while the upper bracts seem to be igen simple. 
Seeds the same as in C. Mexicana. 
3. C. obtusifolia (Torr. et Frem.); foliolis cuneato-obovatis obtusissi- 
mis integerrimis supra glabris subtus pubescentibus; bracteis 
unifoliolatis ; sepalis lacerato-3—5-dentatis; ovario stipite 4—5-ties 
breviore stylo bis breviore; capsula . . . —Torr. et Frem. in 
Frem. Second Report, p. 311. — On the American Fork of the 
Sacramento River, California; flowering in March, Colonel Fremont. 
My only specimen of this species is that of an annual, about a 
span high, but doubtless much larger when mature. The stem is 
branched from the base, and glabrous. The leaflets are about half an 
inch long, and are tipped with a deciduous bristle. Stipules laciniately 
fimbriate. Calyx much shorter than the corolla. Petals yellow, 
oblong-lanceolate. Stipe much exserted. Ovary obovate, with appa- 
rently but few (about 6) ovules. Capsule unknown. 
4. C. angustifolia ; foliolis oblongo-linearibus acutiusculis integerrimis ; 
bracteis superioribus simplicibus; ovario stylum multoties super- —
