clvii. GRAMiNEiE (Stapf). [Hyparrhenia. 
spikelets linear-lanceolate, acuminate, 3-3J lin. long, with the 
tomentum of the fertile, reddish ; lower glume membranous, very 
closely many-nerved, aristulate, bristle up to 3 lin. long : upper 
acutely acuminate, 3-nerved, hairy and ciliate upwards ; valves 
hyaline, reversedly ciliate, lower oblong, narrowly truncate, 3-nerved, 
slightly shorter than the glumes, upper linear to linear-cuneate, 
somewhat shorter, 1 -nerved. Homogamous spikelets similar to the 
pedicelled member of the heterogamous pair, but not aristulate, 
usually larger (up to 4| lin. long) and less hairy.

32. H. phyllopoda, Sta'pf. Perennial, up to 5 ft. high, with intra- 
vaginal innovations. Culms erect, somewhat stout, firm, terete, L 
glabrous and smooth, simple and 4-5-noded below the panicle ; 
lower internodes swollen at the base, with the conspicuous culm- 
nodes 3 lin. from the base. Leaf -sheaths firm, terete, quite glabrous, 
the basal more or less persistent ; ligules scarious, oblong, glabrous, 
2 lin. long ; blades narrowly linear from an equally wide or more 
often long-attenuated base, often almost reduced to the stout dorsally 
rounded midrib, long -tapering upwards to a fine point, over 1 ft. 
by 1 4 lin., very rigid (at least below), glabrous, slightly rough above 
and scabrid along the margins, midrib white above, primary lateral 
nerves about 3 on each side, with about 3 very fine secondary nerves 
between them. Spatheate panicle elongated, narrow, somewhat 
contracted, up to 1J ft. long, of 5-6 mostly mixed up to 5-rayed 
tiers ; subtending leaves with well developed upwards rapidly de- 
creasing blades, the lowest resembling the preceding leaves, glabrous , 
the lowest compound rays up to 1 ft. long and 3-noded ; simple 
rays slender, filiform, f-1 in. long. Spatheoles narrowly lanceolate, 
finely acuminate, 1J-1J in. long, scarious, reddish-brown, glabrous, 
permanently boat-shaped, 1 lin. wide in profile ; peduncles filiform, 
8-15 lin. long, recurved, laterally exserted from the spatheoles, 
always shorter than these, pubescent upwards, and with long spread- 
ing tubercle-based hairs from the curvature. Racemes at length 
epinastically reflexed, somewhat dense, § to almost 1 in. long, about 
8-12-awned per pair, glabrous or nearly so except on the joints 
and pedicels, dark purplish or olive-brown; bases rarely over J lin. 
long, dark-pubescent on the inside, often with long rigid hairs near 
the tips, the longer produced into a dark short ovate auricle ; joints 
filiform, obliquely truncate, a little over 1 lin. long, shortly ciliate, 
cilia pale, up to J lin. long ; pedicels similar, slightly longer, with 
a minute auricle. Homogamous pair of spikelets 1 at the base of 
the lower raceme only. Fertile spikelets linear-oblong, including the 
callus up to 2-2J lin. long, olive-green with reddish tips or dark
