GYMNOPdGON Beauv Spikelets with 1 perfect flower, sometimes 1 or 2 neuter or staminate subses- sile florets above the perfect one, remote along one side of a flliform continuous rliaoliis, forming slender unilateral spikes; rhachilla prolonged beyond the floret as a slender often awned rudiment; glumes narrow, subequal, rigid, scabrous on tlie strong keel, equaling or exceeding the florets ; lemma thin, bearing a slender straight awn from just below the apex; palea about as long as the lemma. — Perennials, with short rather broad rigid leaves and numerous slender spikes, at first erect, at length widely divaricate or reflexed. (Name composed of , naked, and irdyoiii, a beard, alluding to the reduction of the abortive flower to a bare awn.) 1. G. ambiguus (Miohx.) BSP. Culms tufted from a short rootstook, .rigid, erect or ascending, 2-5 dm. high; sheaths overlapping, blades often approximate, thick, rigid, spreading, i-6 cm. long, 1 cm. or more wide ; spikes solitary or in 2's along a striate axis, becoming widely divaricate when exserted from the sheath, spikelet-b earing to the base; awn of floret longer than the glabrous lemma; rudiment long-awned. {G. racemosus Beauv.) — Sterile sandy or gravelly ground, N. J. to Mo., Fla., and Tex. Aug., Sept. Pig. 135. 2. G. brevifblius Trin. Resembling the preceding; culms more slender, from a decumbent base; leaves 2-4 dm. long, 4-9 mm. wide, involute in drying; spikes usually less numerous, more distant, naked at the base, spikelet-bearing from about the middle; awn shorter than the hairy lemma; one or two sterile florets sometimes present, rudiment usually awnless.—Sandy ground, N. J., and 135. G. ambigiuus. Inflorescence x i/g. Spikelet x 21/2. 53. CHLdRIS Sw. Spikelets with 1 perfect floret, sessile in 2 rows
