AuthorTorrey
DistributionSo far, known from only a single specimen: Jackson County, slope above Cane Creek, elev. 2200 ft, 3 March 1999, C. Gallo s.n. (WCUH). FNA maps it just east of Raleigh, so there must be another NC specimen somewhere.

Native of the southern Midwest of the U.S., scattered records eastward.
AbundanceVery rare.
HabitatSlope above a montane stream.
PhenologyFlowering and fruiting March-April.
IdentificationThis is a small species, tufted, with short leaves and short culms. The inflorescences are pale greenish gray and dense.
Taxonomic CommentsThe genus Poa contains some 500 species globally, about 70 in N.A. A typical Poa species has a number of basal leaves, few stem leaves, and a terminal, open inflorescence. The inflorescence is composed of well-spaced whorls of 2-6 skinny branches, usually with short side branchlets and these bearing spikelets. Branches may be strongly ascending, horizontal, or reflexed. Spikelets are composed of 2-6 florets and are generally laterally compressed. Each glume and lemma is acute to blunt, but seldom acuminate as in many Festuca species. Unlike Festuca and Bromus, most Poa species have a small wispy tuft of white hairs at the base of each floret.
