4. CHATACME, Planch. ; Benth. et Hook. f. Gen. Pl. iii, 356. 
Flowers unisexual, moneecious. 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. 
Species 2, in Tropical and South Africa, and Madagascar. 
Margin of leaf entire .. : ‘ 1. C. microcarpa. 
Margin of leaf serrate .. 2. C. serrata. 
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, 1? to 4 in. long, rarely 
shorter or longer, 1-1} 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, 14 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 } in. long.—C. aristata, Engl. Pfl. Ost-Afr.
