Abstract
The name Symphytum nodosum (Boraginaceae) is typified based on the original Schur’s collection preserved in the herbarium of Ivan Franko National University of Lviv (LW). Availability of the original material of S. nodosum allows to clarify the identity of this poorly understood taxon. Morphological distinctiveness of S. nodosum justifies its recognition at the rank of subspecies of S. tuberosum. The updated infraspecific classification of S. tuberosum is proposed, with a new combination (S. tuberosum subsp. leonhardtianum) introduced to accommodate dodecaploid populations (2n=96) of S. tuberosum previously referred to either as S. tuberosum subsp. angustifolium or S. tuberosum subsp. nodosum.
