long-acuminate, mostly 3 in. by 1J-2 lin., scarious, purplish or 
reddish and more or less glaucescent, quite glabrous, at length in- 
rolled from the margins and very narrow ; peduncles filiform, 1| in. 
long, enclosed in the spatheoles, finely hairy about 3 lin. below 
the tips, hairs soft, not spreading. Racemes subcontiguous, up to 
1 J in. long, 2-awned per pair, laterally exserted from the spatheole, 
suberect, never recurved nor epinastically reflexed, the lower sub- 
sessile, the upper with a filiform glabrous base up to 2 lin. long, both 
bases produced into a scarious linear upwards denticulate reddish 
appendage 3J-5 lin. long ; pedicels slender, filiform, 3 lin. long, very 
shortly ciliate up to near the tips. Homogamous pair of spikelets 
1 at the base of the lower raceme only. Fertile spikelets oblong, 
excluding the callus almost 4-5 lin. long, almost terete in cross 
section, greenish or yellowish, glabrous ; callus very slender and 
acute, 2-3 lin. long, densely bearded, hairs of the beard up to lb lin. 
long. Glumes coriaceous, equal, lower 2-mucronate (mucros up to 
1 lin. long), slightly flattened on the back with a narrow very pro- 
nounced groove projecting as a slender ridge on the inner side, 
11 -nerved, the slender middle nerve in the groove, which is flanked 
by the 2 stout innermost lateral nerves, all the nerves only visible 
by transmitted light, keels very short, like the tips and mucros 
scaberulous ; upper glume oblong, shortly 2-lobed with a mucro 
or bristle (up to 2J lin. long) from the sinus. Lower floret reduced 
to a linear-oblong 2-nerved ciliate hyaline valve 3J lin. long. 
Upper floret ^ : valve stipitiform, minutely 2-dentate ; awns 
stout, yellowish, up to 5 in. long, shortly fulvously hirtellous. Val- 
vule 0. Anthers 2 lin. long. Pedicelled spikelets linear to subu- 
late-lanceolate, 6J-8 lin. long, glabrous, olive- green or slightly 
reddish ; the lowest glume subherbaceous, with or without a ter- 
minal bristle, up to 3 lin. long, very closely many-nerved, keels 
rigidly ciliolate upwards ; upper membranous, very acute, 3-nerved, 
spreadingly ciliate ; valves hyaline, narrowly linear, ciliate, 6J lin. 
long, the lower 3-, the upper 1 -nerved ; anthers 2 J lin. long. Homo- 
gamous spikelets similar to the pedicelled but muticous or only 
shortly mucronat z.—Androymon macrolepis, Hack, in Flora, 1885,

Culms erect or geniculately ascending, with powerful root-fibres, 
sometimes producing stilt-roots from the lower nodes, glabrous 
and smooth, rather slender, rarely up to 2 lin. thick, simple and 
3- or 4-noded below the panicle, or with mixed branches from the 
lower nodes. Leaf-sheaths terete, moderately firm, most or at
