Discussion

The type locality of Sphagnum wilfii in the Queen Charlotte Islands of British Columbia is a site on a pygmy pine slope near the coast. This species has been collected only infrequently but is fairly common in southeastern Alaska. The combination of red pigment, the rather large and triangular to triangular-lingulate stem leaves and the quinquefarious, loosely spreading branch leaves should identify it where it occurs. See also discussion under 68. S. bartlettianum.
