Personalities of Russian amateur botany, 2. Alexander Mikhailovich Polilov (1869–?), a forgotten plant collector in Russian Lapland, and his collection of Hieracium pasense
Alexander Polilov collected many zoological and botanical specimens during his service as a medical doctor for the Arctic Ocean Hydrographic Expedition (1898–1915). Basic details of Polilov’s biography are presented. His botanical collections originated from the Kola Peninsula and are housed at LE. On the basis of a specimen collected by Polilov, Hieracium pasense was described as new to science from the north-western part of Murmansk Region, Russia. This species is related to H. gemellum from Sweden and is distributed in a small area between Kirkenes (Sør-Varanger, Norway) and Vichany Bay (Murmansk Region, Russia); its presence in Norway is documented with herbarium specimens at H. Hieracium eurofinmarkicum (as a synonym) and the Russian occurrence of H. gracilentipes (misidentification) are included into this species here, with an updated description and a distribution map. A lectotype of Hieracium gemellum subsp. eurofinmarkicum is designated. On the basis of its limited distribution area, the conservation status of the species is assessed as Endangered.
