Abstract
The taxonomic status of the species complex Hedysarum spinosissimum L. (s.l.) has been evaluated on the basis of the phenetic variation within and between populations. Twenty-five characters were measured on plants grown from seeds of 9 populations of H. spinosissimum ssp. capitatum and 12 populations of H. spinosissimum ssp. spinosissimum from the western Mediterranean basin. Data were analyzed by means of multivariate methods. Stepwise discriminant analysis led to conclusions similar to those derived from principal components analysis. The results are discussed from a systematic point of view. On the basis of vegetative and floral characters, numerical analyses supported two morphologically distinct groups of operational taxonomic units corresponding to the predominantly selfing H. spinosissimum and the mostly outcrossing H. capitatum. Key words: Hedysarum spinosissimum L., phenetic variation, morphological contrast, Mediterranean basin, multivariate analysis.
