Flowers unisexual, monoecious. Male : Calyx deeply 5-partite ; 

 segments induplicate-valvate, concave, obtuse. Stamens 5 ; fila- 

 ments erect ; anthers dorsifixed above the base, ovate-oblong. Pistil 

 rudimentary, surrounded by stiffish hairs at the base. Female : 

 Calyx-segments flatter than in the male. Ovary sessile ; ovule 

 pendulous from the apex ; style central, divided to the base into a 

 pair of long, slender, stigmatose branches. Drupe globose ; exocarp 

 thick, hard when dry ; endocarp thin, bony. Embryo bent double ; 

 radicle short ; cotyledons applied face to face, the outer much thicker 

 than the inner. — Lofty shrubs or small trees, much branched, the 

 branchlets armed with short axillary spines. Leaves alternate, 

 short-stalked, entire or serrate, coriaceous, one-nerved and penni- 

 veined. Stipules connate along one margin enveloping the terminal 

 bud, caducous. Male flowers in dense axillary cymes ; female 

 solitary or few.

1. C. microcarpa, Rendle. A stiff shrub or a small tree (up to 

 25 ft. high) ; much branched ; branchlets more or less hirtellous 

 when young, becoming glabrous and ashen grey in colour and armed 

 with solitary or geminate axillary spines. Leaves distichous, 

 shortly petioled, stiffly coriaceous, oblong-elliptic to ovate-elliptic, 

 acute or obtuse, often apiculate with an awn-like prolongation of 

 the mid-vein ; base obtuse to rounded, generally slightly unequal ; 

 margin entire, reflexed in dried specimens. If to 4 in. long, rarely 

 shorter or longer, 1-lJ in. wide, with a median nerve prominent on 

 the lower face, and numerous weakly prominent spreading-ascendent 

 lateral nerves with a conspicuous intervening reticulation, generally 

 glabrous, rarely pubescent on the lower face ; petiole 2-4 lin. long. 

 Male flowers greenish, in dense short bracteate cymes in the leaf-axils 

 or at the lower leafless nodes of young shoots ; pedicel stout, scarcely 

 exceeding the flower, enveloped at the base by the ovate bract and 

 bracteoles. Sepals concave, IJ lin. long, puberulous on the back. 

 Filaments equal to the sepals ; pistil-rudiment 1 lin. long, with a pair 

 of abortive stigmas. Drupe ellipsoid-globose, beaked with the per- 

 sistent style-bases, about J in. long.— C. aristala, Engl. Pfl. Ost-Afr.
