49. H. diplandr a A Stapf. Perennial, up to overl2 ft. high, densely 
tufted from a short descending rhizome with mostly intravaginal 
innovations. Culms robust, up to over 3 lin. in diam., simple and 
3-9-noded below the panicle, terete, glabrous. Leaf-sheaths terete, 
tight, firm, the lower often up to 1 ft. long, glabrous and smooth ; 
ligules very firmly scarious, truncate, hardly up to 1 lin. long, 
ciliolate ; blades linear f rom an equally broad or somewhat attenuated 
base, tapering to a long very fine point up to over 2 ft. long by 3-5 
lin., very firm, more or less rigid, pale green or faintly tinged with 
red, usually densely hirsute behind the ligules and just above them, 
otherwise generally glabrous, smooth except at the very scabrid 
margins and tips. Spatheate panicle large, narrow, loose, often 
over 2 ft. long, with pubescent or shortly bearded nodes, bearing up 
to over 10 tiers ; tiers distant below, approaching each other above, 
few- to 8-rayed, mostly mixed, lower compound rays often over 6 in. 
long and up to 5-noded; simple rays of the ultimate tiers J-l in. 
long, of the lower tiers much longer, up to over 2 in. ; lower and 
intermediate subtending leaves resembling the preceding ones, 
the following with rapidly decreasing blades. Spatheoles lanceolate, 
finely acuminate, 1-1 J in. long, 1J lin. wide, scarious, reddish, pur- 
plish or brownish-yellow, glabrous, for a short time boat-shaped 
during flowering, then inrolled from the margins, but never tightly ; 
peduncles filiform, 3-4 lin. long (rarely up to 5), hairy upwards, hairs 
silky, up to 1 lin. long. Kacemes subcontiguous, laterally exserted 
from the spatheoles, at length epinastically reflexed, mostly 5-8 lin. 
long, dense, glabrous or almost so, except for the cilia of the 
joints and pedicels, 6- (rarely 4- or up to 8-) awned per pair, 
bases dorsally compressed, pubescent on the inner side, trun- 
cate, without an auricle, the longer (upper) up to 1 lin. long ; 
joints linear, slightly widened with obliquely truncate tips 1 lin. 
long, shortly ciliate ; pedicels finely filiform, up to If lin. long, cilia 
as in the joints. Homogamous pairs of spikelets 2 with each raceme, 
very close, forming an imperfect involucre to the raceme, similar to 
the pedicelled spikelets of the heterogamous pairs, if not slightly 
larger, and always muticous. Fertile spikelets linear-oblong, 2J-3 lin. 
long, including the callus, yellowish or pale green often tinged with 
brown upwards, glabrous or very scantily and minutely pubescent,
