Root long tapering. Stem from one to three feet high, round, erect, 

 simple, hairy, (as is the whole plant), and rough, with pale rigid bristles 

 arising from a tuberculated base. Leaves lanceolate, single ribbed, 

 the lower ones with footstalks spreading, the upper narrower jnd 

 sessile, of a dull green. Inflorescence terminating the stem in a long 

 compound spike. Spikelets arising from the axis of the upper leaves, 

 crowded, recurved. Floioers unilateral, sessile, from the axis of a narrow 

 bractea. Calyx of five linear segments, mostly of unequal lengths. 

 Corolla bell-shaped, downy, its tube shorter than the calyx, the seg-

 lengths, and one is often not longer than the corolla. Anthers oval. 

 Pistil longer than the stamens. Style hairy. Stigma deeply cloven, 

 spreading. Nuts four, spreading, rough, with tubercles.
