Palms with the habit and foliage of Korthalsia, but with flagelliferous 
leaves. Spadiz very slender, loosely panicled; branches filiform ; peduncle 
very long, pendulous, prickly, usually adnate to the sheath of the leaf 
opposite; spathe small, solitary, membranous, narrow, flattened, beaked, 
at length split down the ventral face; flowers polygamous, in pairs, the 
Upper ebracteate, the lower bracteate and bracteolate. Male Jt. Calyx 
small, 3-fid; lobes triangular, valvate; stamens 6, on the bases of the 
petals, anthers linear; pistillode minute. Fem. f. Calyx of the male;
