摘要

Mandevilla (Apocynaceae) is a neotropical genus which is well represented in Brazil. A recent taxonomic revision of the Brazilian species of Mandevilla subgenus Mendevilla included eight new species, one of them from the State of Pernambuco. Nevertheless,, while preparing a survey of Apocynaceae from the Brazilian semi-arid region, a new species of the subgenus was recognised. Mandevilla Souza-Silva Rapini J.F.Morales is here described and illustrated. It is a twining plant with elliptic, glabrous leaves and hypocrateriform, purple flowers, known only from the VAC do Catimbau National Park. in the State of Pernambuco.
