* C. occidentalism Linn. ; DC. Prod. ii. 497 ; Bot. Peg. t. 83, widely- 
spread in the tropics, is frequent in Mauritius, Podriguez, and 
Seychelles, but introduced. It is a robust shrubby annual 3-5 feet 
high, with long-stalked abruptly pinnate leaves with a single gland 
placed just above the base of the petiole, 4-5-jugate large ovate or 
oblong acute leaflets, flowers in axillary and terminal corymbs, oblong 
membranous nearly free sepals, middle-sized yellow petals, 7 perfect 
and 3 barren stamens, and an ensiform curved glabrous torulose pod 
4-5 inches long with 20-30 seeds. Casse puante. 
* C. Sophera , Linn. ; DC. Prod. ii. 492 (C. chinensis, Jacq. Ic. t. 73), 
a native of Tropical Asia, is established in Mauritius in plains at 
Moka and Plaines- Wilhelms. It is very near C. occidentalism but 
differs by its more shrubby habit, more numerous narrower leaflets, 
and shorter broader more turgid pods which are scarcely at all 
torulose. 
* C. Tora, Linn. ; DC. Prod. ii. 493 (C. obtusifolia, Linn.), spread 
round the world in the tropics, is naturalised in Mauritius in waste 
ground and fields near Port Louis and other parts of the island. It is 
an erect shrubby glabrous annual, with petioled abruptly -pinnate 
leaves, 3-jugate sessile obovate-oblong glaucous membranous leaflets 
1-1^ in. long, flowers in nearly sessile pairs in the axils of the leaves,
