Abstract
Sphagnum alaskense Andrus & Janssens, sp. nov. is described as a new species in section Sphagnum. It is a weakly to moderately minerotrophic species occurring from Alaska south to the state of Washington. Sphagnum alaskense differs from S. centrale on the basis of weak or absent stem cortical cell fibrils, branch chlorophyll cells lacking thickened end walls in transverse section, and branch leaf hyaline cells often with ridges running parallel to the long axis of the leaf where the hyaline cells overlap the overlying chlorophyll cells.
