As a result of a revision of Pilocarpus Vahl (Rutaceae), three new species of Pilocarpus Vahl (Rutaceae) from Brazil are described and il¬ lustrated: Pilocarpus alatus C. J.Joseph ex Skoru¬ pa, Pilocarpus carajaensis Skorupa, and Pilocarpus sulcatus Skorupa.Data on the geographic distri¬ bution, habitat, and phenology are given for all the new taxa.Pilocarpus is a neotropical genus described by Vahl (1797), encompassing shrubs or small trees occurring from the south of Mexico through Central America and the Lesser Antilles and Greater An¬ tilles to the south of South America.The majority of the species occur in Brazil, where they are found in habitats characterized by various climatic con¬ ditions, soils, and vegetation types throughout the country.Skorupa's (1996) revision of Pilocarpus recog¬ nized 16 species, including three new species in Brazil.This revision took into consideration not only morphology, as did Kaastra (1982), but also wood anatomy, n -alkane distribution patterns of fo¬ liar epicuticular waxes, chromosome numbers, and pollen morphology as additional sources of taxo¬ nomic evidence.
