ABSTRACT
This work presents a floristic study of Sapindaceae in the Marambaia Restinga, Rio de Janeiro (between 23°04'S, 44°00'W and 23°02'S, 44°34'W). We recorded six genera and 14 species: one shrubby-arboreal Allophylus puberulus (Cambess.) Radlk.; two arboreal Cupania emarginata Cambess. and Matayba intermedia Radlk.; one arching herb Cardiospermum corindum L., and ten climbing plants, Paullinia coriacea Casar., Paullinia meliifolia Juss., Paullinia racemosa Wawra, Paullinia revoluta Radlk., Paullinia trigonia Vell., Serjania cuspidata Cambess., Serjania dentata (Vell.) Radlk., Serjania eucardia Radlk., Serjania ichthyoctona Radlk., and Urvillea rufescens Cambess. Among the recorded taxa we highlight Paullinia coriacea, a species exclusive to restingas; Paullinia revoluta, a new record for the State of Rio de Janeiro; and Cardiospermum corindum, recorded through a unique specimen collected 32 years ago, without new records ever since.
