The Sphagnum Species of Massachusetts

This study incorporates the knowledge gained from the many genetic studies completed in the past 25 years with traditional morphological- and ecological-based species concepts to arrive at an updated taxonomy for the Sphagnum species in Massachusetts and New England. In total, 43–44 Sphagnum species are documented for Massachusetts and 53 Sphagnum species are documented for all of New England. The study provides a county checklist as well as the determination that 21 species are potentially rare in Massachusetts. Four (or five) new state records are documented for Massachusetts: S. divinum and/or S. diabolicum, S. ×mississippiense, S. ×missouricum, and S. tenellum.
