Leopoldinia
''Leopoldinia'' is a mostly monoecious genus of flowering plant in the palm family from northern South America (Colombia, Venezuela, northwestern Brazil),〔(Kew World Checklist of Selected Plant Families )〕 where they are known as jará palm or pissava palm. The two known species are commercially important,〔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〕 especially ''L. piassaba'', which yields sustenance and construction material. The genus is named for Maria Leopoldina, archduchess of Austria, and Brazilian empress.〔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== The trunks are clustering in ''L. major'', occasionally clustering in ''L. pulchra'', and solitary in ''L. piassaba''; they reach 15 cm wide to 6 m tall, and are usually covered in old, extremely fibrous leaf bases. The pinnate leaves, up to 5 m, are carried on long, hairy petioles which disintegrate into black, fibrous masses against the trunk. The 1 m leaflets are once-folded, linear, regularly arranged, and either acuminate or briefly bifid.〔 The much branched inflorescence is short, brown, and hairy and emerges within the leaf crown. There may be male and female flowers on different inflorescences, they may alternate along the same branches, in some cases the female flowers are proximal while the male's are distal, some are hermaphroditic and others are simply, but rarely, dioecious. Developing from one carpel, the fruit matures to red in color, may be ellipsoidal, laterally flattened or disciform,〔 and contains one seed.〔
