2. H. huillense, Stapf in Hook. Ic. PI. sub t. 3033. Perennial from 
a nodose rhizome. Culms 1J ft. high, slender, 4-5-noded, glabrous, 
upper internodes exserted. Leaf-sheaths glabrous, tight, terete, 
the uppermost bearded at the nodes ; ligules membranous, truncate, 
1 lin. long ; blades terete, junciform, slightly channelled towards 
the base, up to 1 \ ft. long, lj-f lin. in diam. at the base, hairy along 
the channel. Panicle of 3 racemes on a very short common axis ; 
racemes up to 4 in. long ; joints subfiliform, slightly thickened 
upwards, 2 lin. long, ciliate, upper cilia 2 lin. long, disarticulating 
obliquely ; pedicels very similar but usually slightly shorter and the 
hairs longer. Spikelets narrowly oblong, 3-4 lin. long, greyish 
tinged with purple, callus pungent, 1 lin. long, shortly hairy. Glumes 
equal ; lower membranous, lanceolate, when flattened out minutely 
truncate, hairy along the sides or also on the back, intracarinal 
nerves 5-6, greenish above ; upper glume narrower, 3-nerved, 
minutely ciliolate' Lower floret reduced to an oblong obtuse 2- 
nerved ciliolate valve, up to 3-J lin. long. Upper floret $ : valve 
narrowly linear, about 3 lin. long, 1-nerved, gradually passing into 
the awn, which is up to 1 in. long, tightly spirally twisted and hairy 
for about J in. from the base and more or less kneed 3 lin. above the 
base ; valvule 0. Anthers unknown. — Pollinia huillensis, Rendle

3. H. G-ossweileri, Stapf. Perennial, csespitose ; innovation- 
shoots intra vaginal. Culms up to 2J ft. high, terete, 2-noded, 
glabrous, surrounded at the base by the firm persistent leaf -sheaths. 
Leaf-sheaths terete, tight, shorter than the internodes, the basal 
strongly striate, glabrous or more often hirsute upwards, the cauline 
glabrous, uppermost node bearded ; ligules ovate, obtuse, scarious, 
up to over J lin. long, hairy on the back ; blades terete, junciform, 
slightly channelled towards the base, up to 1 ft. long, hardly more 
than J lin. in diam., hirsute at the base or up to the middle, then 
glabrous or almost glabrous all along. Raceme solitary, about 5 in. 
long, exserted from the uppermost sheath, not very fragile ; joints 
very slender, 3J-4 lin. long, glabrous, disarticulating with an oblique 
linear-oblong scar; pedicels similar, but slightly shorter, ciliate, 
lower cilia short, uppermost up to 3 lin. long. Spikelets 6 lin. long, 
including the callus which is 1 J-2 lin. long. Glumes subequal ; 
lower linear-oblong, obtuse or truncate in the sessile, linear-lanceo- 
late and minutely truncate in the pedicelled spikelet, loosely whitish-
