Haywood County, Art Loeb Trail, south of Black Balsam parking area, woodland seep.bog, elev. 5900 ft., 23 May 1993, Dan Pittillo 12092 (NCU).

Subspecies inexpansa occurs from Lab. to AK, south to NY, WV, OH, IA, AZ, CA; disjunct to high Appalachians of NC.
AbundanceVery rare. However, it should be sought in other high elevation wetlands.
HabitatHigh elevation seepages and fens.
PhenologyFlowering and fruiting May-August.
IdentificationNarrowspike Reedgrass is a more robust plant than C. canadensis (although not taller), the leaves broader and the inflorescence thicker and denser. Spikelets measure 4-5 mm (vs. 3-4 in the former), and the lemma awn is much thicker than the callus hairs (vs. about same width and thus hard to pick out).
