27 (3x). - Greenland. - Böcher and Larsen (1950, for H. groenlandicum).
Geography: Amphi-Atlantic: ICE CAN GRL.
Notes: The two Greenland microspecies Hieracium amitsokense and H. sylowii are only very tentatively assigned here. They do not fit very well.
According to Scoggan (1979), a plant that reaches the Arctic on southeastern Hudson Bay and in northern Labrador (Ramah at 5852'N) might be H. groenlandicum Arv.-Touv., Spicil.: 31 (1881). Nordic authors (e.g., Omang) have assumed Arvet-Touvet's and Almquist's H. groenlandicum to be the same. The former name obviously predates the latter one. The Arvet-Touvet species has been suggested to be part of H. vulgatum Fr. s. lat. (Strother 2006b) but that group is not otherwise known as native to Greenland or North America. We provisionally apply the name combination based on a Greenland plant until it is made clear that the two meanings of the name "groenlandicum" are synonymous.
