Abstract

Subtribe Phaseolinae Benth. has 20 species in four genera in the Brazilian State of Paraná. Vigna Savi has the largest number of species (12), followed by Macroptilium (Benth.) Urb (5), Phaseolus L. (2), and Lablab Adans. (1). The latter two genera are represented by only cultivated species. According to IUCN criteria five species were classified as threatened. The species occur in different vegetation types, including restinga (sand dune vegetation), estepe (grasslands), cerrado (savanna-like vegetation), and moist habitats, like riverbanks. Paraná is the southern limit of distribution for three species in Brazil. We provide identification keys, illustrations, descriptions, and comments on taxonomy, biogeography, and flowering and fruiting periods of the species.
