A new species of Arachis (Fabaceae) from Mato Grosso, Brazil, related to A. matiensis

Abstract

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
