Abstract

A new approach for sampling taxonomic circumscriptions by estimating intrataxon variability yielded some noteworthy data. The data are presented for the phenetic distances computed between plant specimens which had been determined in the classical taxonomic manner. The paper complements one to appear in the American Journal of Botany in which summary statistics support the hypothesis that the phenetic distances (phenetic affinities) and their variances can quantify taxonomic circumscriptions by providing estimates of the similarity between various members of the same taxa. The names of the taxa are listed and the phenetic distances between specimens of a large number of taxa at various levels in the family and the respective variances are presented in nine tables.
