The genus Sphagnum in Alberta

Abstract
There are 21 species of the genus Sphagnum presently known from Alberta. A multiple-access key and an illustrated, dichotomous key are given for the species, and the habitat and distribution of each species in Alberta are presented. The species of sphagna that occur in the province have either widespread or continental tendencies in their distribution patterns. Oceanic and sub-oceanic species are absent from the flora.
