22. C. zambesica, Oliv. Nearly allied to C. nigricans. Branches 
slender, erect or ascending, the leaves thinly pilose with spreading 
weak hairs. Leaves nearly as in C. nigricans, the midrib of the leaflets 
more excentric and the basal gland on a slender stipes. Stipules per- 
sistent, lanceolate-subulate, 8-5 lines long. Pedicels solitary or in 
pairs, from a little above the axils, at length about $in. long. Flowers 
small, the outer finely acute sepals about 3 lines long. Legumes 
14 in., as in C. nigricans. 
Mozamb. Distr. Zambesi, Dr. Kirk! 
The difference in the gland of the petiole and the longer pedicels are, I suppose, of 
sufficient importance to separate this plant specifically from C. nigricans. 
23. C. nigricans, Vahl, DC. Prod. ii. 498. Stem erect from a few 
inches to 2-3 or even 5 ft., terete, more or less sparsely pilose with 
weak spreading hairs exceeding a minute pubescence. Leaves dis- 
tichous, 2-4 in. long ; common petiole with a distinct or obscure sessile 
gland below the lowest pair; leaflets 8-18-jugate, linear to oval-ob- 
long obtuse prominently mucronate, costa not far removed from the 
median line with few free lateral nervures converging longitudinally, 
finely pubescent or glabrate, usually from }—-1 in. long. Stipules per- 
sistent, lanceolate-subulate. Flowers very small, 3—5 lines diameter, 
solitary or 2-8-5 together on very short supra-axillary pedicels. Sepals 
2 lines long, the outer acute, inner obtuse, sometimes apiculate. Petals 
subequal in length. Stamens 10, all perfect or 8 rudimentary ; anthers 
linear, dehiscing at and towards the apex. Legumes erect, nearly 
straight, flat, 2-valved, shortly pubescent, 7—-11-seeded, 1—1} in. long, 
2-2} lines broad. Pedicels, in fruit, stout, 1-2 lines long. Cotyledons 
plane, extending from end to end of the larger diameter of the seed in 
transverse section; albumen thin.—C. micrantha, Guill. et Perr. Fl.

occasionally attaining 2 or 3 ft. or more in height. Stem terete. Leaves
