VALLS, José F. M.  e  SIMPSON, Charles E.. A new species of Arachis (Fabaceae) from Mato Grosso, Brazil, related to A. matiensis. Bonplandia [online]. 2017, vol.26, n.2, pp.143-149. ISSN 0524-0476.

In the original description of Arachis matiensis, two isolated populations, from the municipality of Cáceres, Mato Grosso State, Brazil, were listed as possibly representing a different species, but the analysis of additional materials, and further morphological study were considered necessary to reach a decision in that regard. New herbarium and germplasm collections in the area, additional morphological studies, and inter- and intraspecific crossing results now support the description of A. jacobinensis, a new species of the taxonomic section Procumbentes.

Palavras-chave : Central Brazil; groundnut; Leguminosae; Procumbentes.
