Unlike Sphagnum angustifolium and S. annulatum, S. balticum has stem leaves exerted at right angles to the stem. It also has fewer and weaker hanging branches than does S. angustifolium, which make the stem itself often visible and the stem leaves easier to see. Sphagnum balticum also lacks the paired pendent branch buds between the capitulum rays as seen in S. angustifolium. In Sphagnum kenaiense there are sometimes spreading stem leaves but this species has 2 hanging branches per fascicle. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Sphagnum oregonense is currently known only from the type locality. Sporophytes of it are unknown. It is associated with other minerotrophic bryophytes such as Meesia triquetra, Calliergon cordifolium, and Campylium polygamum. This is a curious species that has an obvious close relationship with sect. Cuspidata. When wet it is similar in appearance to S. subsecundum but upon drying the sightly undulate and recurved branch leaves give it the charactereistic appearance of this section. The branch leave porosity is also more similar to that of species in sect. Cuspidata than that found in sect. Subsecunda.
