more or less oblique, margin entire, 6-7 in. long, up to 3 in. wide, 

 smaller on fruit-bearing branches, coriaceous, glabrous, S-nerved, 

 nerves slightly depressed above, prominent beneath, veins prominu- 

 lous ; petiole stout, 4-9 lin. long, channelled above, glabrate. 

 Inflorescence minutely puberulous, axillary, several times longer than 

 the petiole, paniculate, many-flowered ; fertile flowers few, inter- 

 mixed with the male. Sepals concave, broadly elliptic to elliptic - 

 obovate, about 1 lin. long in the fertile ($) flower, slightly shorter 

 in the male, sparsely puberulous on back and margin. Ovary 

 densely hairy. Stigmas fleshy, dilated, 2-lobed. Drupe large, ovoid-

12. C. Brownii, Rendle in Journ. Bot. 1915, 298. A small tree, 

 monoecious ; branchlets glabrescent. Leaves shortly petioled, ulti- 

 mately thinly coriaceous, oblong-elliptic to broadly elliptic, apex 

 more or less acuminate, base unequal, blunt to rounded, margin 

 entire or with a few short irregular teeth in the upper portion, 2|-5 J 

 in. long, IJ-S in. wide, glabrous, upper face hard, 3-nerved, nerves 

 somewhat depressed above, prominent below, cross-veins more or 

 less parallel, prominulous ; petioles J-J (rarely f) in. long. Inflor- 

 escences much shorter than the leaves, barely exceeding the length 

 of the petiole to about one-third the length of the leaf ; male flowers 

 numerous, sessile or shortly stalked ; fertile flowers above, few, with 

 longer stalks. Sepals concave, elliptic, puberulous on the back, 

 barely 1 lin. long. Ovary glabrous, with a dense ring of white hairs 

 at the base. Stigmas broadly linear, fleshy, somewhat flattened,

Flowers polygamous. Male : Calyx membranous, deeply 5- (more 

 rarely 4-) partite; segments concave, induplicate-valvate in bud. 

 Stamens equal in number to the sepals ; filaments short, erect, subulate ; 

 anthers attached dorsally, ultimately exserted. Pistil rudimentary. 

 Fertile : Calyx as in the male in the $ flowers, but with the segments 

 nearly flat when stamens are absent. Ovary sessile ; ovule pendulous 

 a little below the apex ; style central, divided deeply or to the base
