Summary

Historical infrageneric classifications of the genus Drosera L. took into account the external morphology of its species, especially style division, but also data from palynology, trichome morphology and chromosome numbers. Nevertheless, when confronted with the molecular phylogenetic reconstructions, all existing classifications were unsuccessful in circumscribing a monophyletic D. section Drosera, due to the high homoplasy of morphological traits in that section. Hence, a new classification congruent with the phylogeny and based on monophyletic groups became necessary.
