Labrador is excluded from the range of Luzula wahlenbergii, but in Flore Nordique (vol1, p. 419), there are 2 distribution dots in north-coastal Lab., and 1 from near Shefferville (not sure if it's in the border or not), so Labrador should be added to the range of L. wahlenbergii if these reports are correct.
