G. ambiguus Prel. Cat. N. Y. 69. 1888. Culms 12-18' tall, erect, or decumbent at the base, simple or sometimes sparingly branched, smooth and glabrous. Sheaths short, glabrous, excepting a vil- lous ring at the summit, crowded at the base of the culm; ligule very short; blades 1-4' long, 2"-6" wide, lanceolate, acute, cordate at the base, spread- ing, smooth or a little scabrous above; spikes slender, spikelet-bearing throughout their entire length, at first erect, the lower 4'-8' long, at length widely spreading; spikelets, exclusive of awns, 2"-2i" long; first scale snorter than the second; third scale ex- ceeded by the second, the callus at the base hairy, the awn 2"-2" long. In dry sandy soil, southern New Jersey to Kansas, south to Florida and Texas. 2. Gymnopogon brevifolius Trin. Short- leaved Beard-grass. Fig. 546. Gymnopogon brevifolius Trin. Unifl. 238. 1824. Culms l°-2° long, from a decumbent base, simple, slender, smooth and glabrous. Sheaths shorter than the internodes, sometimes crowded near the middle of the culm; ligule very short; blades l'-2' long, 1 "-4" wide, usually spreading, lanceolate, acute, cor- date at the base; spikes very slender, spikelet-bearing above the middle, the lower 4'-6' long, at first erect, finally widely spreading; spikelets, exclusive of the awns, 1 J" long; first scale shorter than the second; third scale equalling or exceeded by the second, short- awned, sparingly villous or glabrous, the callus hairy.
