Annual or perennial from a slender woody base, glabrate or 
strigillose. Stems 1-6 dm. high, erect or ascending, branching, 
spreading, strigillose on the angles, often glabrate or glabrous and 
glaucous, striate above; stipules setaceous, often persisting; peti- 
oles 1-3 cm. long; leaves 6 cm.—1 dm. long, oblong or linear-ob- 
long in outline; leaflets 7-17, 2-5 cm. long, linear, linear-ob- 
long or oblong-cuneate, obtuse, or acute at each end, apicu- 
Jate, glabrous above, strigillose or glabrate, lighter and often 
glaucous beneath ; racemes terminal and axillary, 1-2 dm. long ; 
peduncles ancipital; flowers 510 mm. long, very short pedicelled ; 
bracts setaceous ; calyx-teeth as long as the tube; corolla white, 
turning purple; vexillum minutely pubescent; legume 3-5 cm. 
long, 3-4 mm. wide, linear or slightly falcate, strigillose or gla- 
brate ; seeds 6-10, oblong brown. 
A very variable species with a long and complicated list of sy- 
nonyms. Known everywhere in tropical and subtropical coun- 
tries. Two distinct strains have been collected in the United 
States, the broader-obtuse leaved form occurs in East Florida, and 
the narrow acute-leaved form (C. tenella) in Texas, Arizona, etc. 
O. Kuntze (Rev. Gen. Pl. 173) has united c. purpurea and 
several other species to C. villosa L. The latter has a villous 
calyx with long, acuminate teeth and a short reflexed, tomentose 
legume and is not known from America.

ern Central America, Eastern South America to South Brazil, and
