rough upwards, lower internodes long ; secondary branchlets 
capillary, bearing 4-1 spikelets approximate upwards ; pedicels very 
short to 1| lin. long, with truncate tips. Spikelets shortly lanceolate,, 
acute, 1-1 J lin. long, green with an apical tuft of fine long hairs from 
the upper glume. Glumes thinly membranous, unequal ; lower 
lanceolate, acute, half the length of the spikelet or less, 1-3-nerved 
or almost nerveless, glabrous ; upper corresponding in length and 
outline to the spikelet, 5-7 -nerved, with some scattered short hairs on 
the back and sides and a slender tuft of long ones (up to 1J lin.) 
from the tip. Lower floret barren ; valve very similar to the upper 
glume ; valvule reduced to a tiny hyaline scale. Upper floret Q 
oblong, acute with a broad back, 1 lin. long, smooth, yellowish or 
whitish ; valve and valvule papery ; anthers f lin. long. — Durand

Perennial, up to over 1 ft. high. Culms very slender, geniculately 
erect from a prostrate rooting branched base, simple or very sparingly 
branched above it, terete, glabrous and smooth, up to 7- or more- 
noded. Leaf-sheaths tight, terete, subherbaceous, finely and promi- 
nently striate, densely ciliate, otherwise glabrous and smooth ; 
ligule reduced to a minutely ciliolate rim ; blades lanceolate from a 
much constricted to almost petiolate base, acutely acuminate, about 
1J in. by 5-6 lin., spreading, flat, very thin, green, quite glabrous^ 
or here and there with a few fine tubercle-based hairs, margins very 
scabrid, midrib very fine, primary lateral nerves delicate, 2-3 on. 
each side, distant, with 4-5 secondary nerves between, connected 
by more or less distinct cross-veins. Panicles shortly exserted, 
flexuous, 2 to over 3 in. long, somewhat contracted, rather scanty, 
somewhat irregularly divided and rarely beyond the second degree ; 
common axis filiform, terete and like all its divisions glabrous and 
smooth or almost so, internodes few, up to over f in. long ; primary 
branches obliquely erect to suberect, the lowest up to 1J in. long, 
bearing from low down or the lowest from some distance above it 
few remote or approximate spikelets, or owing to abortion bare 
high up ; pedicels very short to over 2 lin. long (sometimes the 
terminal). Spikelets oblong, acute, up to over 1J lin. long, pale 
green, faintly suffused with pink, glabrous. Glumes thinly mem- 
branous, unequal ; lower broad-ovate, obtuse, 1 -nerved or nerveless ; 
upper corresponding in length and outline to the spikelet, 5-nerved. 
Lower floret reduced to a valve very like the upper glume. Upper 
floret , oblong, acute, 1 J lin. long, yellowish, smooth ; valve and 
valvule subcoriaceous ; anthers § lin*. long.— Durand & Schinz. .
