DELIMITACIÓN DE LAS ESPECIES ARGENTINAS DEL GENERO INGA (MIMOSOIDEAE) MEDIANTE TÉCNICAS NUMÉRICAS

Abstract

Ingais represented in Argentina by six species and one variety. However doubts emerge about thevalidity of these taxa. Phenetic relationships were studied among 75 specimens belonging to the sevenrecognized taxa, in order to evaluate their validity. A morphological matrix of 46 characters was ana-lyzed by clustering and conglomerate methods. The dendrogram and the principal components analyses(PCA) show six groups, consequently six species can be clearly recognized:I. saltensis, I. marginata,I. laurina, I. virescens, I. affinis, andI. uraguensis. A key for the identification of species is presentedtogether with distribution maps in Argentina.
