Discussion

The distribution of Cynodontium tenellum is fairly well understood for Canada but not for the United States because of confusion with 3. C. alpestre (see discussion thereunder). The present treatment follows W. C. Steere (1978) and R. R. Ireland et al. (1987). The problem in nomenclature of C. tenellum is still unresolved (G. S. Mogensen 1980; B. H. Allen 2005).
