Some of the racemes were infested with the pupae of a small insect of the 
family Chalcididae which caused an enlargement of the sessile spikelets, their 
lower glume attaining a length of 5-9 lin. and becoming quite coriaceous and 
smooth in the lower part, the perfect insects escaping through a hole in the back 
of the glume.

Perennial, up to over 3 ft. high, tufted from a short oblique rhizome ; 
innovations intra- and extra- vaginal, with firm glabrous cataphylls. 
Culms erect, sometimes from an arching base, wiry or woody and 
solid below, glabrous and smooth, simple below for 4-6 nodes 
below the panicle, with mixed or barren erect branches from some 
of the lower nodes. Leaf -sheaths of the innovations compressed 
and keeled, otherwise terete, glabrous and smooth, tight, the lower 
usually longer than the internodes, at length slipping off or decaying 
with the exception of the long-persistent dark bases ; ligules scarious, 
truncate, up to over 1 lin. long, ciliolate or glabrous ; blades linear 
from a more or less narrowed base, long -tapering to a fine point, up 
to 6 or 8 in. by 1-3 lin., slightly flaccid or rigid, flat, glaucous, 
glabrous or with a few long fine spreading hairs near the base, 
smooth, or rough upwards, margins scabrid, midrib slender on the 
back, whitish and wider on the upper side, lateral nerves indistinctly 
raised. Spatheate panicle elongated, usually scanty, lax, J ft. to 
Ij (rarely 2) ft. long, of 1-7 distant 2-4- (rarely 5- or 6-) rayed tiers 
or with the lowest branch undivided at the base and 2-3-noded ; 
simple rays subfastigiate, very slender, filiform, 1J to over 4 in. 
long, often more or less kneed at the nodes ; subtending leaves 
with usually well developed blades, herbaceous to subherbaceous, 
glabrous, greenish. Spatheoles linear-lanceolate, tapering to an 
acute point, 1J-2J in. long, usually glabrous or more or less hairy, 
early turning reddish or red, at length loosely inrolled : peduncles 
at length If to almost 3 in. long, subterminally long-exserted and
