Abstract

As part of a review of wild peanut relatives in Paraguay, new botanical collections were conducted and specimens deposited in various herbaria and databases were re-examined. As an initial outcome of this review, specimens corresponding to Arachis microsperma Krapov., W. C. Greg. & Valls from the Arachis section and A. sesquijuga Valls, L. C. Costa & Custodio, of uncertain sectional location were identified. These two species, previously considered endemic to Brazil, are now added to the flora of Paraguay. Populations of A. microsperma, which were previously reported only from southern Mato Grosso do Sul, Brazil, significantly expand the distribution area, primarily within the Amambay and Concepción departments of the Paraguayan territory. Meanwhile, the population of A. sesquijuga in Amambay department represents the southernmost record to date for the species.
