Flowers dioecious, apetalous. Male : Calyx globose, minutely 

 apiculate and closed in bud, splitting into 3-4 valvate lobes. Stamens 

 (in the African species) 6-12, inserted on a slightly raised receptacle, 

 either mixed with inter-stamina^ glands only or (in the African species) 

 surrounded by an extra-stamina 1 cup, but without inter-staminal 

 glands; filaments free; anthers erect, obovoid, 2-celled, dehiscing by 

 extrorse longitudinal slits. Rudimentary ovary 0. Female : Calyx 

 '2-i), or (in the Afiicau species) 4-partite ; segments smaller than in the 

 male. Disk 2-lobed, Ovary hi.spid or velvety, 2-3-celled (2-celled in 

 the African species) ; outer solitary ; stigmas free, recurved from the 

 base, plumosely Inciniate thioughout. Capsule (in the African species) 

 2-Goccous ; cocci subglobose ; splitting loculicidally. Seeds almost 

 spherical, usually arillate ; testa crustaceous, foveolate-reticulate or 

 nearly smooth ; albumen fleshy ; cotyledons broad, flat. — Small trees 

 or shrubs with stoutish twigs. Leaves alternate, usually distinctly 

 petioled, margin crenate or toothed ; stipules small, deciduous. 

 Flowers in lateral or axillary, dense or rather lax uniformly floriferous 

 racemes, small or minute ; male flowers usually several, female flowers 

 usually solitary to a bract. — Claoxylon § Uiscoclaoxylon, Miill. Arg. in
