Very densely cespitose, culms from very short to 15 or 20 cm. 
high, much exceeded by the leaves, triangular, rough on the angles, 
reddish-brown tinged and strongly fibrillose at base, phyllopodic; 
sterile culms aphyllopodic, erect, the sheaths filamentose. Leaves 
numerous and conspicuous, the blades from very short to 20 cm. 
long, at flowering time 1.5-2 mm. wide, in age wider, very rough, 
flat with somewhat revolute margins; terminal spike staminate,
