Dictyocaryum
''Dictyocaryum'' is a monoecious genus of flowering plant in the palm family found in South America which is closely related to the ''Iriartea'' genus; they are commonly called araque or palma real. As many as eleven species have been described but this number is reduced to three in most current accounts. The genus name translates from two Greek words meaning "net" and "nut", describing the thick network of raphe fibers around the seed.〔Riffle, Robert L. and Craft, Paul (2003) ''An Encyclopedia of Cultivated Palms''. Portland: Timber Press. ISBN 0-88192-558-6 / ISBN 978-0-88192-558-6〕
==Description==
''Dictocaryum'' palms are usually solitary in nature though ''D. ptarianum'' will occasionally cluster in habitat. All three plants have conical masses of stilt roots at the base which are armed with spines. The trunks are conspicuously ringed by leaf scars, to 30 cm wide, and in ''D. lamarckianum'' reach over 20 m in height. All have tall crownshafts and 4-6 large, plumose, pinnate leaves. The leaves may be sparsely to densely tomentose on the rachis and petiole, the leaflets are regularly and widely spaced, up to 60 cm long, dark green on top and glaucous on the underside.
Compared to other palms, the inflorescences in this genus are unusually large, once-branched, and emerge below the leaf crown. Both male and female flowers are white to yellow, growing on the same plant, both with three sepals and three petals. The fruit develops from one carpel, yellow to orange to brown when ripe, containing one basally attached, spherical seed.〔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〕
