Rootstocks caespitose forming dense clumps 
to 50 cm. in diameter; basal scales 0.5-1. 5 
cm. wide, 1.4-4 cm. long, 4-8 per culm, soon 
becoming loose, fibril lose, dark brown; fer- 
tile culm 2-4 mm. wide, 15-100 cm. long, 
isosceles triangular in cross section, lightly 
scabrous or smooth on the main veins and 
angles, erect, heads nodding; leaves 2-15, 
usually 6-7, mm. wide, 5-10 cm. long, 5—8 
per culm, erect for about one-third the length, 
scabrous and toothed on all main veins on 
the underside, glabrous above, shiny, dark 
green to yellow; sheaths loose, dark brown

tending 4-8 cm. above the rootstock, splitting 
along the membrane at maturity; inflores- 
cence 4-25 cm. long, branching, 1-4 un- 
branched spikes arising from a node, 2-15 
nodes per culm, internodes 2-6 cm. long at 
the base shortening toward the apex, each 
node and peduncle enclosed by the base of 
a leafy bract; spikes 0.5-1. 5 wide, 2-10 cm. 
long above the peduncle, androgynous except 
the terminal one at each node which may be 
entirely staminate, 1 to 3 spikes at a node 
enclosed by leafy bract, peduncles 2-5 cm. 
long, enclosed at the base by an ochrea 10-15 
mm. long; pistillate bracts ovate, truncate at 
the base, 2-3 mm. wide, 2.5-5 mm. long,
