Flowers monecious or diccious, apetalous. Male: Calyx globose, 
minutely apiculate, closed in bud, splitting into 3 (rarely 4) valvate mem- 
branous lobes. Stamens usually 2-seriate, occasionally 1-seriate or more 
than 2-seriate, 3-20, rarely more, attached toa slightly convex receptacle ; 
filaments free, as long as the anthers, mixed or not with inter-staminal 
glands; cells narrow-obovoid, free from the base, opening by long) 
tudinal extrorse slits. Rudimentary ovary 0. Female: Calyx 3-, less 
often 4-partite, lobes imbricate. Hypogynous disk of 2-4, usually 3, 
narrow-linear scales alternate with the carpels and about as long 
as the calyx. Ovary usually 3-celled, occasionally 2-celled, very rarely 
4-celled, cells l-ovuled; stigmas free, spreading, linear, fimbriate- 
laciniate throughout. Capsule usually 3-coccous, but sometimes 
2-coccous, didymous, occasionally 4-coccous or by abortion papi 
coccous ; cocci 2-valyed, opening both loculicidally and septicidally an 
separating from a distinct crustaceous or woody columella. Seeds 
almost globose; testa crustaceous, distinctly foveolate-reticulate, com- 
pletely enveloped in a very thin aril; albumen fleshy ; cotyledons flat, 
usually broad, suborbicular, sometimes hardly broader or longer 
than the stout cylindric short radicle-—Herbs or shrubs, annual or 
perennial. Leaves alternate or sometimes the lowest opposite, sect | 
distinctly petioled, membranous, usually dentate or serrate, peninner yeu. 
Flowers in axillary filiform interrupted racemes; males minute, aan’ 
pedicelled, glomerulate, the glomerules many-flowered in racemes wit
