Allagoptera
''Allagoptera'' is a monoecious genus of flowering plant in the palm family found in South America consisting of 5 accepted species. Compared to other genera within the Cocoeae ''Allagoptera'' is described as particularly specialized.〔Uhl, Natalie W. and Dransfield, John (1987) ''Genera Palmarum - A classification of palms based on the work of Harold E. Moore''. Lawrence, Kansas: Allen Press. ISBN 0-935868-30-5 / ISBN 978-0-935868-30-2〕 The genus name is a Greek combination of "change" and "feather", describing the full leaf; it was formerly named ''Diplothemium''.
==Description==
''Allagoptera'' produces very short or acaulescent trunks and in cases where the trunk grows erect it often makes a downward turn leaving the crown below the trunk-base. The trunks in ''Allagoptera'' are among the few in the palm family which tend to bifurcate, producing multiple heads per unit. The pinnate leaves are gently arching to 2 m and are carried on long, slender petioles which are adaxially channeled. The single-fold leaflets are regularly or irregularly arranged on the rachis each protruding into a different plane, creating a plumose leaf. The unusual spicate inflorescence emerges from within the leaf-crown carrying the pistilate flowers basally with the staminate flowers growing distally. The single-seeded fruit is yellow to brown, growing in crowded clusters.〔Riffle, Robert L. and Craft, Paul (2003) ''An Encyclopedia of Cultivated Palms''. Portland: Timber Press.
