New data for systematics of the genus Zeravschania (Apiaceae) and related taxa based on the nrDNA (ITS) sequences

Abstract

All 13 species of the genus Zeravschania were studied in molecular and morphological analyzes. The molecular study showed that Zeravschania is a clearly paraphyletic taxon including monotypic genera Demavendia and Haussknechtia. Further phylogenetic, anatomical and morphological studies are needed to confirm taxonomic position of these genera. Zeravschania afghanica confirms its placement in the genus Zeravschania, not in Cephalopodum or Selinum. Dichoropetalum knappii confirms its placement in the genus Dichoropetalum, not in Zeravschania.
