Abstract

Rhynchosia Lour. has a pantropical distribution, presenting two main centers of diversity for about 230 species, one in Africa (140 spp.) and another in the Americas, where 55 species are recorded, of which 19 occur in Brazil. The most recent taxonomic treatment to genus was published by Grear in 1978, which treated only the American species. Morphologically, Rhynchosia is fairly uniform, making it difficult to delimit species. It can be characterized by the presence of unifoliolate or trifoliolate leaves with persistent or deciduous stipules, lax or congestous inflorescences with yellow flowers, a calyx with five well developed lobes, and a legume fruit with two seeds. Two species of this genus has identification problems, Rhynchosia minima (L.) DC. and R. edulis Griseb., and deserve special attention for a taxonomic study, because they have morphological characteristics that overlap, often leading to erroneous identifications in the herbaria. Thus, this work aims to the morphometric study of vegetative and reproductive traits with the purpose of evaluating the limits of these two species of Rhynchosia. Considering the characters that are already used as diagnoses for R. minima and R. edulis, it is also intended to evaluate and select the most important discriminate characters for these taxa. The data will be treated by multivariate analysis methods, UPGMA and PCA. Thus, according to the pattern observed through the results obtained from the multivariate analyzes, it will be possible to verify if the species will remain as separate taxa or if they can be synonimized under a single taxon.
