 spreading hairs. Flowers small.

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, 3-5 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 

 1^ 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 j 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 J— 1 in. long. Stipules per- 

 sistent, lanceolate-subulate. Flowers very small, 3-5 lines diameter, 

 solitary or 2—3-5 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 3 rudimentary; anthers 

 linear, dehiscing at and towards the apex. Legumes erect, nearly 

 straight, flat, 2-valved, shortly pubescent, 7-11 -seeded, 1-1 J in. long, 

 2-2J 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.

24. C. mimosoides, Linn. ; Vog. in Walp. Rep. i. 837. An annual 

 or frutescent and persisting a few years, various in habit, erect or 

 diffuse, simple or much branched, pilose pubescent or nearly glabrous, 

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