Flora das cangas da Serra dos Carajás, Pará, Brasil: Polygalaceae

Abstract

A floristic treatment of Polygalaceae species from the cangas of the Serra dos Carajás (state of Pará, Brazil) is presented. We provide descriptions, taxonomic keys, illustrations, and taxonomic notes for Polygalaceae taxa from cangas. Six species were found, distributed in four genera: Bredemeyera divaricata, B. floribunda, Caamembeca spectabilis, Polygala adenophora, Securidaca diversifolia e S. rivinifolia, none of them endemic to the region or the state of Pará.
