|discussion=<p>The description of <i>Cynodontium alpestre</i> above follows authors who did not consider the species to be a variant of <i>C. tenellum</i>. Authors who do unite the two (as <i>C. alpestre</i>) conflate the characters, emphasizing those of <i>C. tenellum</i>. The present description and that of, for example, H. A. Crum and L. E. Anderson (1981) for <i>C. alpestre</i> would not be parallel and would be misleading. <i>Cynodontium tenellum</i> as <i>C. alpestre</i>, for example, would have strongly 2- to multistratose margins and sessile perigonial buds, and the cells would be smooth on the lamina; all these features are contradicted by the present description. The distribution in the flora area is poorly known for the United States because of confusion with <i>C. tenellum</i>, and here follows W. C. Steere (1978) and R. R. Ireland et al. (1987). See G. S. Mogensen (1980) for clarification of the taxonomic position of <i>Cynodontium alpestre</i>.</p>
