Distributio geographica. In Europa boreali frequens est, 

 in partibus mediis et australioribus tantum in regionibus monta- 

 neis crescens (jam in Dania rara teste Brandt et Rostr., Lich. 

 Dan. p. 45); in regionibus arcticis item est frequens saltem in 

 Lapponia et in insulis Spitsbergensibus (teste Malmgren in Th. 

 Fr. Lich. Spits, p. 30). In Asia provenit in regionibus borealibus 

 (ad Nahratsch prope flumen Konda in Sibiria occidentali ipse legi; 

 ad Surgut in prov. Tobolsk leg. Augustinowicz : mus. Hort. Petrop.; 

 prope Jakutsk: Nyl., Lich. Middendorff. p. LVI; in ins. Sachalin 

 leg. Augustinowicz et in insulis prope Kamtschatka leg. Dombrow- 

 skij : mus. Hort. Petrop.) et arcticis (prope Kolymsk in tundris leg. 

 Augustinowicz: mus. Hort. Petrop.; prope ChaUspagor in regione 

 Tundrae Sibiriae septentr.-occident. teste Miill., Lich. Finsch. p. 2) et 

 mediis [in Sibiria orient. (Turczaninow), Davuria et Mont. Altaicis 

 (Sosnin), Caucaso (Kolenati): mus. Hort. Petrop.; in Turchestania, ut 

 ait Friedrich 1. c. p. 391]. In America septentrionali : in regionibus 

 arcticis, borealibus et alpinis, velut in ins. Vancouver (Lyall), ad 

 Kotzebue Sound (Beechey), Cape Krusenstern (Beechey), Saskatche- 

 wan (Bourgeau), Observation Island (Scouler), Groenlandia arctica
