Additional Information at NatureServe

Diagnostic Characteristics:
Plants in tufts, 1.5-3 mm high, dark, greenish-yellow or sometimes dark-green or yellow-brown above, blackish-brown below. Leaves 2.5-5 mm long, flexuose-spreading, not much altered on drying, obovate and clasping at the rather short base, abruptly narrowed to a long, linear, subtubulose limb; margins erect, finely serrulate nearly to the shoulders, both blade and margin of subula bistratose.

Management:
The habitat for this species is especially sensitive to changes in hydrology and not likely to withstand much alteration. Grazing or browsing pressure, vegetation removal, or any hydrologic changes (i.e. stream alterations road construction) would be detrimental.

Global Range:
Known from Pennsylvania and, perhaps disjunctively, the southern Appalachians (in Georgia, North and South Carolina, and Tennessee); also reported from West Virginia (Crum and Anderson 1981). Range extends into Virginia.
