Summary A simple method is described for defining multi‐state taxonomic characters from measurement data. Bar diagrams are used to observe the pattern of variation of the measurements both within and between the units to be classified. The method gives definitions which are superior to arbitrary subdivisions of the range both in revealing taxonomic correlations and in reducing the effects of sampling error.
