Discussion

Sphagnum centrale is most similar to S. alaskense but seems to have no range overlap with that species and is also considerably more minerotrophic. In the field it lacks the often reddish tinge of S. palustre and is larger than S. affine. See also discussion under 2. S. alaskense and 9. S. papillosum.
