Perennial, caespitose, erect, rather robust, attaining about 

 13 decim. in height ; roots fibrous, stout-filiform, hard, strong. 

 Culms simple, slender, with several nodes, terete, solid, firm, 

 smooth but usually finely striate when dry, glabrous but often 

 puberulent under the nodes, often somewhat flexuous ; intcr- 

 nodes elongate, the lower ones wholly encircled with the sheaths; 

 nodes slightly prominent. Leaves long, linear, gradually 

 tapering above to an attenuated-acuminate tip at the apex, 

 gradually attenuated at the base, spinuloso-scabrous on margin, 

 chartaceous, about 4-10 mm. wide, glabrous, or thinly ad- 

 pressed-pubescent dorsally, villoso-pubescent at the base, green 

 above, not glaucous beneath, purple-ferruginous when dried, 

 the superior ones diminished in size ; midrib slender, paler, 

 prominent beneath : main-nerves about 6 on each side; nervulcs 

 delicate, closely arranged between the main-nerv^es ; ligule short, 

 truncate, thin, minutely ciliolated on margin; minutely puberu- 

 lent above dorsally ; sheath long, terete, closely encircling 

 the culm, often purple-ferruginous when dry, finely striate, 

 entire and glabrous on margin, glabrous or pubescent above, 

 densely rufo-tomentose with soft hairs in the basal ones.
