Additional Information at NatureServe

Diagnostic Characteristics:
This sedge is in the section Stellulatae. The few leaves are less than 1.3 mm wide (for subsp. capillacea) and occur at the bottom third of the stem; the stem is scabrous on the angles. Perigynia green and two-sided (flattened) and not winged but it does appear thickened (white and spongy) at the base. Perigynia are less than 4 mm long and are generally widely reflexed or spreading in the small and few flowered spike.

The habitat for this species is very specialized and not likely to withstand much alteration. Avoid changes in moisture conditions at the site. Grazing or browsing pressure, vegetation removal, hydrologic changes (i.e. timber removal upstream, stream alterations) would be detrimental.
