(name means a tuft of leaves at the top). Palmdcew, tribe Cocolnew. Spiny tropical American palms: caudex erect, solitary, ringed and swollen at the middle, densely spiny: lvs. terminal, pinnately cut; seg ments narrowly linear-lanceolate, long, obliquely acumi nate, the naked margins recurved at the base; midnerves, rachis and petiole with long spines: fr. globose or ob long, glabrous or prickly; black or brown. Species 8, mostly difficult to distinguish; allied to Cocos. They need a rich, sandy loam. The chief danger with young plants is overpotting, as few leaves are on a plant at a time, and the roots are not abundant.
