ligule a fringe of very short hairs; leaf-blades linear, acuminate at 
the apex, narrowed toward the ciliate base, scabrous on the margins, 
the primary ones 8 to 16 cm. long, 5-10 mm. wide, the uppermost 
longest. Axis of the panicles scabrous as are also the ascending, 
slightly flexuous branches. Spikelets obovate, 2.5-3 mm. long; first

and third glumes 7-nerved, pubescent with short spreading hairs. 
General distribution: in dry rocky woods, Connecticut to Penn-
