1430 Heracleum sphondylium L. subsp. montanum (Schleich.) Briq.
Syn.: H dissectum Ledeb.
This subspecies occurs, in Hultén's opinion, in two main distribution areas, one in C. and S. European mountains and one in Siberia. However, the circumscription of subsp. montanum is, according to G. Weimarck (pers. comm.), a matter of discussion. The Siberian population, shown on the map, represents possibly a separate taxon.
