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.) |
Sporophytes of Sphagnum splendens are unknown. The lack of any fibrils in the branch leaf hyaline cells gives it an unusually glossy appearance that should make it readily identifiable in the field. The facts that it differs from S. fallax in only one character and that it is known only from the type locality make S. splendens questionably distinct to some observers. More investigation is needed. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
