Genetic diversity within and among two Argentinean and one Mexican species of Acacia (Fabaceae)

Acacia is a pantropical genus comprising>1450 species. Following Vassal's treatment Acacia is considered as a single genus with three subgenera (Acacia, Aculeiferum and Phyllodineae). Acacia caven, A.curvifructa and A.farnesiana belong to subgenus Acacia and the relationship between them is...
