silky pubescence. Leaves subsessile, from obovate to obovate-oblong, 2 to 4in. 
long. Stipules forming wings from one node to nearly the next, lanceolate 
deltoid. Racemes bearing few yellow flowers, on elongated often leafy peduncles. 
Bracts small, persistent, ovate, acuminate. Calyx about 5 lines long, densely 
silky, tube campanulate. Bracteoles inserted above the base. Corolla not much 
exserted. Pod linear-oblong, long-stalked, glabrous, about 2in. long. Seeds

Hab.: An Indian species now naturalised in many localities. 
2. C. verrucosa (warted), Linn.: DC. Prod. ii. 125; Benth. FI. Austr. ii. 
179. A stout erect minutely pubescent annual of 1| to 3ft.; branches divaricate 
with prominent angles almost winged. Leaves usually ovate-rhomboidal, 2 to 
4in. long, but passing sometimes into ovate-acuminate or almost lanceolate and 
5 or Gin. long, always very obtuse. Stipules semilunar or falcate, horizontally 
spreading. Flowers pale-blue, in loose terminal or leaf-opposed racemes. Calyx 
about 4 lines long, the lobes acuminate, longer than the tube, all free, the lowest 
rather the narrowest. Standard broad, above |fn. diameter. Ovary sessile, very 
villous all over or on the inner side, with above 20 ovules. Pod oblong, villous, 
1^ to 2in. long. — Wight, Ic. t. 200 ; Bot. Mag. 3034 ; Rheede Hort. Mai. ix. t. 
29 ; F. v. M. Fragm. iii. 54, ix. 156. 
Hab.: Rockingham Bay, Armit; Endeavour River, It. Broicn ; Cape Upstart, M‘Gillivray ; 
Bowen River, Bowman; Rockhampton, Tliozet ; Edgecombe Bay, Dallachy. 
The species is common in East India, and is now spread over many parts of tropical Africa 
and America. — Benth. 
3. C. crispata (crispate), F. v. M. Herb.; Bentli. FI. Austr. ii. 179. A low 
much-branched softly villous herb, the stems diffuse or ascending and not 
exceeding 1ft. Leaves from obovate-oblong to narrow oblong-cuneate, or broadly 
linear, very obtuse, ^ to lin. long, villous on both sides. Flowers small, few, in 
short loose terminal racemes. Bracts and bracteoles minute, ovate-acute or 
lanceolate, villous outside, glabrous inside. Calyx about 3 lines long, deeply 
cleft, the 3 lower lobes shortly united, the 2 upper ones broader, all lanceolate, 
very glabrous and sometimes viscous inside, villous outside, the margins often 
recurved and crisped after flowering. Petals scarcely exceeding the calyx. Ovary 
sessile, very villous, with 2 ovules. Pod ovoid, villous, scarcely exceeding the 
calyx. Seed usually solitary, black and shining. 
Hab.: Islands of the Gulf of Carpentaria, R. Brown. 
This plant is referred by F. v. Mueller, Fragm. iii. 55, to C. ramosissima, Roxb., which it 
resembles in many respects, but which, in its large flowers and broad reflexed viscous bracts, is 
nearer to C. lunulata, Heyne (India). Both these species are allied to C. paniculata (Trop. 
Asia), and C. crispata is undoubtedly connected with them, although rather more distinct from 
all than they are from each other. — Benth.
