Aiphanes ulei (Dammer) Burret

Aiphanes is a genus of spiny palms which is native to tropical regions of South and Central America and the Caribbean. There are about 26 species in the genus, ranging in size from understorey shrubs with subterranean stems to subcanopy trees as tall as 20 metres (66 ft). Most have pinnately compound leaves (leaves which are divided into leaflets arranged feather-like, in pairs along a central axis); one species has entire leaves. Stems, leaves and sometimes even the fruit are covered with spines. Plants flower repeatedly over the course of their lifespan and have separate male and female flowers, although these are borne together on the same inflorescence. Although records of pollinators are limited, most species appear to be pollinated by insects. The fruit are eaten by several birds and ... ...Read More

 Distribution [C][3]


Aiphanes species have a long history of human use. The remains of carbonised seeds thought to belong to A. horrida have been found in archaeological sites in Colombia dating back to about 2800 BP; seeds of this species are still consumed and are traded in local markets. Aiphanes horrida is also widely planted as an ornamental, as is A. minima. The fruit or seeds of A. deltoidea, A. eggersii, A. linearis and A. minima are all consumed locally. The palm heart of A. macroloba is consumed by the Coaiquer people of northwestern South America. Aiphanol, a compound isolated from A. horrida, has shown significant inhibitory activity against cyclooxygenases;[48] inhibition of these enzymes can provide relief from the symptoms of inflammation and pain.
