minutely puberulous upwards, ciliolate. Lower floret reduced to a 
linear-oblong truncate hyaline 2-nerved ciliolate valve, 2 lin. long. 
Upper floret g , as long as the lower or nearly so ; valve linear, 
hyaline, shortly 2-fid, faintly 3-nerved, sparingly ciliolate ; awn about 
4 lin. long, very fine, kneed and twisted near the base, bristle 
whitish ; valvule 0. Stigmas laterally exserted, 1 lin. long. Pedi- 
celled spikelet similar to the sessile, but slightly smaller and nar- 
rower, glabrous. Glumes unequal ; the lower produced into a long 
fine point ; the upper and the lower valve as in the sessile spikelet. 
Upper floret $ , (always ?) awnless. Anthers 1 lin. long. — Andro -

Perennial, compactly caespitose ; 
rhizome short, emitting stout black roots, innovations intra- and 
extra-vaginal. Culms numerous, up to 3 ft. high, more or less com- 
pressed below or sometimes stout (up to 2 lin. in diam.) and terete, 
3-noded below the inflorescence, with the internodes exserted, 
glabrous, smooth, branching from the middle upwards, branches 
solitary or 2-4-nate, distant. Leaf-sheaths glabrous, those of the 
innovations much compressed, keeled, long-persistent, at length 
brown and shining, those of the culms terete, tight, glaucescent, 
short ; ligules scarious, very short ; blades of the innovations 
folded, linear, acute, up to 1-3 in. long and 1J-2J lin. wide, or some 
up to 16 in. long and 3J lin. wide (when flattened out), firm, glabrous, 
glaucescent or dull or purplish, at length reddish, of the culms 
similar, but flat with a constricted base, 2 to over 3 in. long, 3-5 lin. 
wide, sometimes slightly hairy above the ligules, scaberulous along 
the margin, midrib glaucous above, lateral nerves 6-7 ; spathes 
subobtuse, widened upwards from a very narrow base, 1 J-3 in. long, 
subglaucous or livid. Eacemes on filiform glabrous enclosed ped- 
uncles, laterally exserted below the tips of the spathe, 1 to almost 2 in. 
long, 5-9- jointed ; joints slender, slightly dilated upwards, 2J or 
the lowest up to 3 lin. long, ciliate on the outer side from the base, 
on the inner from the middle, with the hairs increasing upwards to 
lf-2 lin. long, glabrous on the back or almost so ; pedicels very 
similar, but with the tips produced into a minute appendage. Ses- 
sile spikelet lanceolate, acuminate, 3J-4 lin. long and slightly over 
1 lin. wide, pale. Glumes subequal ; lower minutely 2-dentate, 
thinly chartaceous, rather flat on the back, with narrow inflexed 
margins, upwards scaberulous, keels and 3 intracarinal nerves 
sparingly hairy from the back ; upper glume slightly shorter, acute, 
obtusely keeled, hyaline, 3-nerved, sparingly ciliate. Lower floret 
reduced to a linear-oblong minutely truncate hyaline 2-nerved
