Arecaceae Schultz Sch. Litoral Piauiense, Delta do Parnaíba, Piauí, Brazil

Abstract

The survey of Arecaceae in Piauí coast showed six species, five of which are native (Astrocaryum vulgare Mart., Copernicia prunifera (Mill.) H.E.Moore, Euterpe oleracea Mart., Mauritia flexuosa L.f. e Orbignya martiana Barb.Rodr.) and one subspontaneo (Elaeis guineensis N. J. Jacquin). Copernicia prunifera and Orbignya martiniana are endemic species. The most frequent species were C. prunifera, A. vulgare and M. flexuosa. C. prunifera is the most used by the local community, explored mainly due to cerifico powder that produces, guaranteeing the income of many families in Ilha Grande Municipality. Astrocaryum vulgare, Elaeis guineensis, Euterpe oleracea are new records for the state of Piauí. Key to identifying the taxa, descriptions and information about the use potential of the species are presented.
