Aconitum moldavicum Hacq. (Ranunculaceae) i jego mieszańce w Karpatach i przyległych obszarach

Herbarium and field studies on Aconitum moldavicum Hacq. in Poland, Ukraine Romania, and partially in Slovakia, were carried out. The species consists of two geographical races circumscribed in the rank of subspecies: subsp. hosteanum (Schur) Graebn. et P. Graebn. and subsp. moldavicum. The pattern of geographical distribution confirms Szafer’s (1930) hypothesis on the eastern Podolo-Volhynian glacial refugium, and the Western Carpathian refugium of the species. The common occurrence of the hybridogenous morphotypes A. m. subsp. hosteanum × subsp. moldavicum in the Małopolska Upland is elucidated by a migratory hypothesis. Other taxa distinguished are putative hybrids scattered across the Carpathians in the sympatric areas of their presumed parents. The key for determination of supraspecific taxa and their hybrids is provided.
