Flowers moncecious, apetalous. Disk 0. Male: Calyx globose, 

 closed in bud, splitting into 4-t3 valvate lobes. Stamens usually 20-30 ; 

 filaments connate below in a column, inserted on the convex receptacle ; 

 anthers narrow-oblong, 2-celled ; anther-cells opening longitudinally. 

 Rudimentary ovary 0. Femnle: Sepals 5-12, in flower denticulate; in 

 fruit accrescent, indurated, pinnatifid. Ovary usually 3-celled, casually 

 4-celled ; ovules solitary in each cell ; styles connate in a stout rather 

 thickened column, often hollow upwards ; stigma terminal, entire or 

 faintly lobed. Capsule breaking up into 3 (less often 4) 2-valved cocci ; 

 valves thinly woody. Seeds globose or subglobose, without a caruncle ; 

 albumen fleshy ; cotyledons broad, flat. — Herbs or shrubs with usually 

 twining stems. Leaves alternate, petioled in the African species, pal- 

 mately nerved from the base, entire or deeply 3-lobed. Flowers in 

 dense axillary peduncled heads, subtended by a pair of large similar or 

 slightly dissimilar leafy entire or lobed membranous usually coloured 

 bracts. Male flowers central and terminal in the heads subtended by 

 smaller bracts and sometimes mixed with fleshy processes representing 

 sterile flowers ; female flowers lateral and basal also with an involucel 

 of smaller bracts.
