A detailed study of 44 accessions representing 38 taxa (76% of the diversity known at present) of pygmy sundews (Drosera sect. Bryastrum) reveals the first naphthoquinone patterns in this lineage, in which previous studies have not yielded reliable evidence for naphthoquinones. While most samples do not display detectable amounts of naphthoquinones as previously reported for the group, ramentaceone is detected in three mutually related taxa, and both ramentaceone and its regio-isomer plumbagin is present in all accessions investigated of D. pulchella.

Keywords: Drosera, phytochemistry, naphthoquinones, chemotaxonomy, plumbagin, ramentaceone
