fringed with cobwebby hairs. Panicle slender, narrow, 2-8 in. 
long; branches short, slender, erect. Spikelets linear-lanceolate, 
compressed, 2—4-flowered, 1-1 in. long, dark-brown or almost black.

to 2000 ft. October—January. 
Easily distinguished from the preceding species by the more slender 
grooved stems, smaller darker spikelets, the presence of bristles, and by the 
smooth biconvex nut.

clothed with chestnut-brown scales. Stems densely tufted, very 
slender, 1-24 ft. high, terete, grooved. Leaves reduced to 2-3

tip into an erect subulate lamina }~2in. long; the mouths of the 
sheaths oblique, glabrous. Panicle slender, narrow, 2-6 in. long; 
branches filiform, erect ; bracts at the base with appressed sheaths, 
and a short erect lamina. Spikelets numerous, compressed, very 
narrow, 4-4in. long, linear-lanceolate, acute, brownish. Glumes
