Trithrinax acanthocoma Drude |}}Trithrinax is a genus of flowering plants in the palm family (Arecaceae), which belongs to subfamily Coryphoideae. The name is derived from ancient Greek, where tri means three, and thrinax trident. It was named in 1837 by Carl Friedrich Philipp von Martius, a German botanist and explorer.[3]Trithrinax species are spiny fan palms native to South America. They are resistant to cold, heat, wind, drought, poor soils and other adverse environmental conditions. Seeds germinate fast, but their overall growth rate is distinctly slow.[4] DescriptionCommon features of Trithrinax species include:

As a consequence, Trithrinax and related genera have been placed in their own tribe, Cryosophileae.[1] HabitatTrithrinax species are spread along vast subtropical zones of South America: Bolivia, Brazil, Paraguay, Uruguay, Argentina. They prefer dry, open or forest clearing, environments, with moderate to cold winters.[7]UsageLeaf fibers are used as raw material for textiles, rustic clothing, and handicrafts. Oil can also be extracted from seeds. Fruits are sometimes used locally, fermented, to produce alcoholic beverages.[7] {{clear}}References1. ^1 {{cite journal| last = Dransfield| first = John|author2=Natalie W. Uhl |author3=Conny B.
