Perennial herbs or low shrubs, covered with stellate pubescence. Leaves alternate or fascic- 
ulate, the blades entire, narrow. Flowers dioecious or polygamous, the staminate ones ebrac- 
teate, in dense clusters arranged in spikes and subtended by leaves, the pistillate ones bibracteate, 
solitary or clustered in the axils; calyx of the staminate flower 4-parted, membranaceous, 
the segments obovate, concave, obtuse, nerveless, pubescent outside; stamens 4, the anthers 
exserted; perianth wanting in the pistillate flower, the bracts conduplicate, obcompressed, 
connate below, pilose. Stigmas 2, filiform, connate at the base. Utricle enclosed in the 
bracts, these forming a long-pilose 2-horned coat, this finally longitudinally 4-valvate, the 
utricle ellipsoid, compressed; pericarp membranaceous, free from the seed. Seed compressed, 
vertical; embryo nearly annular; radicle inferior.
