Characterization of restinga vegetation from the Maracaipe RPPN, Pernambuco, emphasizing physiognomy, flora and abiotic features). The objectives of this study were to produce a list of the flora, describing the physiognomies and relating the life forms with physiognomy from the restinga of a RPPN in Maracaipe. The study area is localized in the coordinates 08031 48 S and 35001 05 W occupying an area of 130 ha, with 76.2 ha of the restinga vegetation. The climate is As and the soil is a Neossol Quartzarenic. The sample period was between July 2003 and July 2005 considering of all life forms. The occurrence of restinga species were used other studies from the Northeastern. Were sampled 187 species, distributed in 148 genera and 71 families. Among these more representative families detached: Poaceae (13 spp), Cyperaceae (12), Myrtaceae (10), Orchidaceae (9), Rubiaceae (8), Bromeliaceae and Fabaceae (7), Mimosaceae and Caesalpiniaceae (6), Euphorbiaceae (5), Annonaceae and Chrysobalanaceae (4). The following physiognomies were determined: unflooded forest, unflooded field and flooded field. These physiognomies showed exclusive species, as Pycreus pelophylus, Ludwigia suffruticosa, Utricularia pusilla and Hydrolea spinosa that were only observed flooded field, the species Buchenavia capitata, Tapirira guianensis, Manilkara salmannii and Sloanea guianensis, detached as emergent in the forest. In order, we concluded that life forms were determinant to separate physiognomic types of restinga, around nutrient and the water table level that also contributes to the colonization of species in a determined physiognomy.
