Summary Variability within and between two species of closely related onions ( Allium cernuum Roth and Allium stellatum Wats.) was measured using methods of cluster and principal component analysis. These two widely distributed but overlapping species are sometimes difficult to distinguish. Analysis with 62 characters supports the classification of the two as distinct taxa. The level of dissimilarity between the two taxa falls within the range of interspecies dissimilarity for the genus.
