Palms with the habit and foKage of Korthalsia, but with flagelliferona 

 leaves. (S^pa^'a! very slender, loosely panioled ; branches filiform ; peduncle 

 very long, pendulous, prickly, usually adnata to the sheath of the leaf 

 opposite ; spathe snaall, solitary, membranous, narrow, flattened, beaked, 

 at length split down the ventral face ; flowers polygamous, in pairs, the 

 upper ebraoteate, the lower bracteate and bracteolate. Male fl. Calyx

 Fruiting calyx as in the male, but petals much narrower and longer. 



Var. angustifolia, Becc. mss. ; more slender, leaflets narrower gradually produced 

 into a slender point, median costa setulose, spathe 4 in. long, much thinner and spadix

Soandent monocarpic spinous palms, stem very long. Leaves flagelli-
