Kobresia simpliciuscula subsp. subholarctica T.V. Egorova
Publ. & Syn.Kobresia simpliciuscula var. americana Duman, Bull. Torrey Bot. Club 83: 194 (1956). Holotype (LCU): Canada: Quebec, Ungava, ... mountain on west side of Koksoak River, 2 miles below the fork, 5742'N, leg. Dutilly, Lepage, and Duman 28,118.
NotesThe specimens inspected from Svalbard, Greenland, and arctic parts of Canada and Alaska belong to subsp. subholarctica, reported to be the arctic race in Russia. Subspecies subholarctica then seems to be the only race in the Arctic. It is similar to subsp. simpliciuscula but the differential characters reported (details in inflorescence, see Egorova 1983, 1992) are deemed taxonomically significant. We do not yet know how consistent the differences are in material from outside Russia.
Chromosomes70-76. - Siberia (N), Far East (N), Alaska, Canada, Greenland. - Several reports.
