Las palmeras (Arecaceae) de los bosques tropicales estacionalmente secos y de piedra caliza kárstica del Perú

Palm trees (Arecaceae) originate from the world’s tropical rainforests and through diversification at least 10% have adapted to ecosystems characterized by some degree of water limitation. In this sense, palm trees that have adapted toSeasonally Dry Tropical Forests (BTES) and Tropical Limestone Karst Rock Forests (BTRCK) in Peru are announced. A review of both the literature and physical and virtual herbarium specimens was carried out and field trips were carried out in wet and dry seasons. 19 species of palm trees were recorded in 11 genera; 15 species and 9 genera in the tribe Cocoseae of the subfamily Arecoideae and four species with two genera in the subfamily Ceroxyloideae. The genera with the greatest presence are: Chamaedorea with four species, followed by Ceroxylon with three species and Aiphanes, Attalea and Astrocaryum with two species each. Palm trees adapted to environments with water limitation correspond to 10% of those present in Peru. Two species are restricted to the western slope, 11 species restricted to the eastern and inter-Andean slopes and two species found on the Pacific and Atlantic slopes. Three species only in tropical limestone karst forests. Chamaedorea fragrans, Prestoea ensiformis and Socratea exorrhiza. Ceroxylon peruvianum is endemic to Peru and inhabits seasonally dry tropical forests.
