Magnoliophyta species of restinga, state of Pernambuco, Brazil.

Abstract

Restinga vegetation occurs along the entire coast of Brazil. The 187 km of coastline of the state ofPernambuco demonstrates a diversity of habitats, such as beaches, dunes, and restingas. The present study sought toelaborate a checklist of the phanerogamic species found there. The species listed were compiled from surveysundertaken between 1951 and 2007, as well as from herbaria collections in that state. A total of 477 species distributedamong 303 genera and 95 families were encountered. The families with the greatest numbers of species were Poaceae(39 species), Fabaceae (34), Cyperaceae (26), Euphorbiaceae (25), Myrtaceae (24), Rubiaceae (20), Caesalpiniaceae(17), Mimosaceae (16), Asteraceae (14), Orchidaceae (14), Bromeliaceae (9), Boraginaceae (8), Malvaceae (8),Solanaceae (8), and Annonaceae, Araceae, Chrysobalanaceae, Malpighiaceae, and Melastomataceae (7 each).Approximately 60 % of the species were common to other restinga areas in northeastern Brazil, and 39.3 % wererestricted to the coast of Pernambuco.
