ABSTRACT
This paper presents a floristic study of the Sapindaceae in a remnant of Semideciduous Forest in the Municipality of Engenheiro Paulo de Frontin, Rio de Janeiro State, Brazil. 20 species in seven genera were identified: three shrubs or trees belonging to Allophylus (three species); six trees belonging to Cupania (four species), Matayba (one), and Sapindus (one); and 11 lianas belonging to Paullinia (four species), Serjania (six), and Urvillea (one). Among these species, Allophylus exappendiculatus Somner, Frazão & Ferrucci, is a recently described species discovered during this study; Paullinia thalictrifolia Radlk. and Serjania gracilis Radlk. had not been collected for more than 40 years in the State of Rio de Janeiro State. This study contributed to the knowledge of the Sapindaceae from a Semideciduous Forest of Southeastern Brazil and added a new species to the national flora.
