The genus Ipomoea (Convolvulaceae) in the state of Rio Grande do Norte, Brazil

Abstract

Melastomataceae are the tenth most diverse angiosperm family in the world and the sixth largest angiosperm family in Brazil. Among the ecosystems associated with the Atlantic Forest, restinga comprises different phytophysiognomies where this family is a conspicuous element. Parque Estadual Paulo César Vinha (PEPCV) is an important area of restinga with various phytophysiognomies and serves as an interesting model for taxonomic studies about Melastomataceae. Thus, from October 2017 to April 2019, we conducted a taxonomic study of the family in this protected area and made ecological observations that have never been discussed for the group in this environment. We recorded 14 species and a preference for open, humid areas. The richest genera were Miconia and Pleroma. In addition to morphological and habitats information, we recorded three new occurrences for this protected area.
