silky above, silvery. sericeous beneath, a stipitate setiform gland between each pair,

** Anthers all perfect. 
7, C. Chamecrista L. (PARTRIDGE PEA.) Stems spreading: leaflets small, 10 to 
15 pairs, linear-oblong, oblique at base, a cup-shaped gland beneath the lowest pair ; 
stipules persistent: flowers large, on slender pedicels, often some of the yellow petals 
purple-spotted at base: anthers 10, elongated, unequal (4 yellow, the others purple): 
pods flat.—In eastern Texas, and extending to Gillespie County and the lower Rio 
Grande. 
8. C. nictitans L. (WILD SENSITIVE-PLANT.) Like the last, but with 10 to 20 
pairs of linear-oblong leaflets, very small flowers on very short pedic els, and 5 nearly 
equal authers.—A common eastern species, but reported froin our range only west of 
the Pecos, 
9. C. procumbens L. Prostrate, hirsute-pubescent: leaflets 4 to 6 pairs, linear,

Nueces and the lower Rio Grande.
