 and amplexicaul at the base, ciliate, pubescent, many nerved, 4-7 cm. long, 

 9-18 mm. broad at the base ; ligule short, fimbriate. Spikes few and dis- 

 tant, 2-4 cm. long ; rachis triquetrous, the angles sharp, very downy. Pedi- 

 cels with a ring of projecting hairs just under the spikelets. Spikelets about 

 8 mm. long ; empty glumes downy, pointed, strongly 3-7-nerved, the lowest
