Sphagnum wilfii H. A. Crum, N. Amer. Fl. II. 11: 90. 1984.

Authors: Richard E. Andrus

Plants densely tufted, capitulum small and indistinct; typically red; forms small tufts in shaded and open sites. Stems red; superficial cortical cells aporose. Stem leaves 1.2 mm or more, broadly triangular to triangular-lingulate, 1.2 or more, apex acute, border broad at base (more than 0.25 width); hyaline cells mostly efibrillose, 1--2-septate. Branches uncrowded, 5-ranked. Branch fascicles with 2 spreading and 1 pendent branch. Branch leaves ovate-lanceolate, 0.7 mm or more, straight, concave, loosely involute from apex to middle or below; concave surface with few (2--4) small, rounded, or elliptic pores, especially in cell angles, concave surface aporose or with 1--2 pores at cell ends. Sexual condition unknown. Spores unknown.

Pine slope; B.C.; Alaska.

The type locality in the Queen Charlotte Islands of British Columbia is a site on a pygmy pine slope near the coast (H. A. Crum 1984). This species has been collected only infrequently$ but seems to be fairly common in southeast Alaska. The combination of red pigment, the rather large and triangular stem leaves and the quinquefarious, loosely spreading branch leaves should identify it where it occurs. See also discussion of S. bartlettianum.
