Flowers polygamous, in small axillary cymes. Perianth of 
hermaphrodite and male flowers deeply 4-lobed, more rarely 3-lobed, 
segments valvate, of female flower less deeply lobed. Stamens as 
many as the perianth-segments. Ovary free, rudimentary in the 
male flower, glabrous ; style short or absent ; stigma densely peni- 
cillate, deciduous; ovule erect from the base. Achene enclosed 
in the persistent enlarged perianth ; pericarp thinly crustaceous. 
Seed conforming to the pericarp; testa membranous; albumen

more rarely suffruticose, generally diffuse in habit, sometimes 
scandent, often pubescent. Leaves alternate, stalked, entire, 3- 
nerved or triplinerved, generally small, with numerous dot-like
