Abstract

The classifications revealed by geometric morphometry and classical morphometry for Drosera rotundifolia, D. ×obovata, D. anglica and D. linearis were compared. We investigated microscopic sections of petioles, analysed with TPS computer programs; and morphomertic characters of leaves, analysed by several multivariate methods. We found that:

  1. the classifications of sundew plants by mean of morphological measurements and geometric morphometry return the similar and well-interpreted results;
  2. the form of petiole middle part transverse section is the effective distinguishing character for the some different species and inter-species hybrids of Drosera;
  3. the consensus configurations are preferable for the geometric morphometry analysis of populations.
