Trichophorum cespitosum (Linnaeus) Hartman. Deergrass, Deerhair Bulrush. Phen: Jul-Sep. Hab: Cliffs receiving fog/cloud deposition and seepage, mostly at high elevations, over amphibolite, granite, gneiss, or schist, notably at Grandfather Mountain, Roan Mountain, Mount LeConte, Whiteside Mountain, and Chimney Rock. Dist: A circumboreal tundra and alpine species, south in North America to the mountains of New England and fens in NY, and to n. IL, MN, montane UT, and OR, common in wet tundra and on alpine summits, disjunct (from NY) to about a dozen sites in the Southern Appalachians of w. NC, e. TN, nw. SC, and ne. GA (Jones & Coile 1988).

Origin/Endemic status: Native

Other Comments: The species may represent a complex of taxa, variously treated at varietal, subspecific , and specific rank; the best taxonomic resolution remains unclear and it therefore seems best to recognize T. cespitosum broadly at this time. The disjunct southern occurrences are certainly relicts of a more widespread distribution during the Pleistocene. Reported for South Carolina by Hill & Horn (1997) and Hill (1999). The spelling ‘cesp-‘ in the epithet is not correctable to ‘caesp-‘.
