12. C. Brownii, Rendle in Journ. Bot. 1915, 298. A small tree, 
moneecious ; branchlets glabrescent. Leaves shortly petioled, ulti-

numerous, sessile or shortly stalked ; fertile flowers above, few, with 
longer stalks. Sepals concave, elliptic, puberulous on the back,

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 malein the 9 flowers, but with the segments 
nearly flat when stamens are absent. Ovary sessile ; ovule pendulous
