the bracts leafy, much overtopping the spikes; 
staminate spike sessile or nearly so; pistillate 
spikes 2-4, oblong, erect, the lower slender-stalked; 
perigynia oblong, 3-angled, striate-nerved, sub- 
acute, 214’’ long; scales broadly ovate, green, not 
at all or very slightly scarious-margined, acute, 
cuspidate or the upper obtuse, 2-3 times shorter 
than the perigynia; stigmas 3.

than or equalling the culm; bracts foliaceous, over- 
topping the spikes; staminate spike sessile; pistillate 
spikes 3-5, erect, densely several-many flowered, the 
lower slender-stalked; perigynia oblong, many-striate, 
114’’-2/ long, sub-acute, beakless, mostly nearly 
twice as long as the ovate scarious-margined acute 
cuspidate or short-awned scales; stigmas 3.

slender, erect or spreading, smooth or nearly so, 6/— 
24° long. Leaves flat, roughish or smooth, 133//-3/7 
wide, the basal shorter than the culm; bracts similar 
to the culm-leaves and usually much exceeding the 
spikes; staminate spike solitary, sessile or short- 
stalked; pistillate spikes 3-5, distant or the upper 
two contiguous, erect or slightly spreading, narrowly 
oblong or cylindric, %’-14’ long, 2’’ thick, densely 
many-flowered, slender-stalked or the upper sessile
