Paullinieae of the restingas of Rio de Janeiro, Brazil: Taxonomy and Distribution

Paullinieae is a predominantly neotropical tribe comprising six genera (Cardiospermum, Lophostigma, Paullinia, Serjania, Thinouia and Urvillea), of which Lophostigma is the only one not found in Brazil. This study was conducted in the sandy coastal plains (restingas) of Rio de Janeiro state. This ecosystem has great biodiversity, but has been constantly threatened by deforestation, human occupation and degradation resulting from tourism. In this area we found 30 species in five genera: Cardiospermum (1 sp.), Paullinia (9 spp.), Serjania (15), Thinouia (2) and Urvillea (3). This data set includes a numerical list of species and a list of all the studied exsiccatae.
These collections of Sapindaceae was found in the main herbaria of Rio de Janeiro state (GUA, HB, R, RB and RBR) and in the digital databases available on the websites of INCT - Herbário Virtual da Flora e dos Fungos (speciesLink Website, 2021) and Reflora (Reflora – Herbario virtual, 2020)
