Trichopteryx] XXVIII. GRAMINEA, 215 
from among the withered leaf-sheaths of last season and enveloped 
at the base by a few leaves reduced to the brown membranous 
sheath or with only a small blade ; stem internodes 2 to 3 like the 
nodes and sheaths glabrous; sheaths cylindrical, close-fitting, 
much shorter than the internodes; ligule a short dense row of 
hairs ; blades slender, convolute, rigid and setaceous, erect, the 
uppermost reaching or overtopping the inflorescence, pubescent 
on the inner face; panicle very dense, spikelike, linear, spikelets 
subsessile or shortly stalked on the very short appressed com- 
pressed branches, lanceolate-subulate, light brown; gl. I. about 
half as long as gl. III., lanceolate, subacute, 3-nerved, dorsally 
flattened, margins incurved with a close line of dark brown warts 
with spreading white bristly hairs; gl. IJ. linear-lanceolate, 
acuminate, blunt, 3-nerved, the involute margin minutely scabridu- 
lously hairy from below the middle to below the tip; gl. III. 
exceeding gl. IT., linear below, tapering above into an acuminate 
awn; 3-nerved ; pedicel of fertile flower slender, bearing short 
basal tufts of hair like the callus, fertile gl. coriaceous, puberulous, 
convolute, inconspicuously 7-nerved with minutely bilobed apex 
between which springs the long awn ; pale linear-tapering, nerves 
strong, approximate. a 
Culms 13 to nearly 2 ft. long, sheathed for about 2 in, at the 
base, internodes 3 to } line in diameter ; cauline sheaths 2 to 3 in. 
long, leaf-blades 3 to 5 in., + to } line in thickness in their natural 
convolute condition. Panicle barley-like, 13 to 3 in. long not 
including the awns; fully developed spikelets # in. long; gl. I. 
4 to 41 lines long, gl. II. 73 lines or slightly less, gl. III. 8} to 9 
lines, pale 4 lines, narrow, flattened, with a bifid apex; pedicel of 
fertile flower slender, 14 line long, exceeding the truncate callus, 
gl. 3 lines long including callus, column of awn pale brown, 
twisted, about 1 in. long, subula greenish 11 to 1} in. long, pale 
narrow, 22 line. The stamens have dropped, but there appear to 
have been 2 in the $ flower. 
A distinct species near 7’. hordeiformis Stapf, but differs in its 
perennial habit, narrow setaceous leaves, glabrous nodes, shorter 
inflorescence and relative lengths of the glumes.

Var. gracilis Rendle var. nov. 
Culms slenderer than in the type with short narrow-linear 
tapering involute leaves, and basal sheaths glabrous like the 
upper ; spikelets smaller, 10 to 13 lines long, and gl. I. less robust 
and generally more acute. Leaves 5 to 11 in, long, 2 lines or less 
in breadth.
