Morphometric analysis of varieties of Acacia caven: (Leguminosae, Mimosoideae): Taxonomic inferences in the context of other Argentinean species

The aims of this study were to evaluate the degree of morphological differentiation between six varieties of Acacia caven and to examine their taxonomic validity in the context of other Argentinean species of the genus. To accomplish these purposes, morphological traits have been analyzed using mult...
