Abstract

A new endemic species, Eranthis tanhoensis sp. nov., is described from the Republic of Buryatia and Irkutsk Province, Russia. It belongs to Eranthis section Shibateranthis and is morphologically similar to E. sibirica and E. stellata. An integrative taxonomic approach, based on cytogenetical, molecular and biochemical analyses, along with morphological data, was used to delimit this new species.

Keywords: Ranunculales; Biochemistry; Russia; cytology; integrative taxonomic approach; morphology; phylogeny.
