Ceroxylon
''Ceroxylon'' is a genus of flowering plant in the Arecaceae family, native to the Andes in Venezuela, Colombia, Ecuador, Peru, and Bolivia, known as Andean wax palms.〔(Kew World Checklist of Selected Plant Families )〕〔Govaerts, R. & Dransfield, J. (2005). World Checklist of Palms: 1-223. The Board of Trustees of the Royal Botanic Gardens, Kew.〕〔Sanín, M.J. & Galeano, G. (2011). A revision of the Andean wax palms, ''Ceroxylon'' (Arecaceae). Phytotaxa 34: 1-64.〕
The species are almost exclusively montane and include the tallest palm (and thus tallest monocotyledon), ''C. quindiuense'', which reaches in height, and species growing at the highest altitude of the palm family (Arecaceae), at more than in elevation.
==Description==
''Ceroxylon'' palms develop single, smooth, wax-covered, often whitish cylindrical trunks encircled by ringed leafbase scars. ''Ceroxylon'' species are dioecious (the individual plant produces flowers of only one sex). Leaves are pinnate. Inflorescences emerge from among, and often project conspicuously beyond, the leaves. Round fruits, up to one inch in diameter, are red or orange at maturity. Many ''Ceroxylon'' species are endangered by habitat destruction.
Two species of Andean wax palms, ''C. quindiuense'' and ''C. alpinum'', provide nesting sites and food for species of Colombian parrots now in danger of extinction, ''Ognorhynchus icterotis'' and ''Conurus icterotis''.
