Gen. & Sp. PL 1: 110 (1815). (Fig. 16.) An erect or ascending perennial, 6 to 12 dm. higli, with rather dense cyhndrical panicles and linear-lanceolate leaves to 5 dm. in length. Culms rather stout, compressed and more or less branched below, striate, scabrous below the nodfes and panicle, otherwise smooth; nodes glabrous, sheaths loose, striate, glabrous, usually exceeding the inter- nodes, scabrous on the keel, bearded at the apex, margins ciliate-fringed; ligule fringed with straight white hairs, 3 to 4 mm. long; leaf-blades rigid, linear-lanceolate, scarcely nar- rowed at the base, gradually tapering to the long acuminate apex, 1 to cm. Avide, sca- brous on both sides or rarely nearly smooth, generally with a few long white hairs toward the base, midvein prominent throughout. Panicle pale green, strict, thyrsoid, cylindrical, usually tapering to the apex, 1 to 3 dm. long, 1 to 2 cm. in diameter; common axis angular, sparingly villous; branches short, contiguous, densely flowered, erect, exceeding their internodes, the lower generally slightly remote; setae solitary or in pairs, slender, flexuous, antrorsely scabrous, 1 to 2 cm. in length. Spikelets ovate- globose, about 2 mm. long, acute; first glume one-third to one-half as long as the spikelet, broadly ovate, acute, inflated, and inclosing the base of the spikelet, 3 to 5 nerved; second glume two-thirds to three- fourths as long as the spikelet, broadly ovate, obtuse, apicu- late, 5 to 7 nerved; third glume equaling the spikelet, slightly inclosing it by its infolded margins, sulcate, 5-nerved, subtending a lanceolate, hyaline palea about its own length; flowering glume strongly convex, apiculate, striate, and rather prominently transversely undulate-rugose, especially below, the inclosed palea equaling
