Resumen:
Multivariate and univariate analyses based on morphological characters were carried out in order to understand the taxonomic status of S. spiniflora and S. chacoënsis. Fifteen morphological characters from herbaria specimens were recorded and analyzed by the Kruskal-Wallis test and principal components analysis. The type specimens and all available herbaria material were examined for the taxonomic study. The results showed that both taxa differed only by the character of stem pubescence and this feature displayed high variability; in parallel, the CPA demonstrate that no clearly separated group were recognized. Based upon these results, the synonymy of S. chacoënsis to S. spiniflora is proposed.
