and pedicels very sparingly ciliate or quite glabrous.

It is worth noting that in one of the specimens one culm bears a solitary 
raceme, whilst another culm has a pair of racemes as usual ; the structure of 
the spikelets of this form is exactly as in typical A. Dummer i. 
}/ 31. A. Pseudo-Schinzii, Stapf. Perennial, 2-3 ft. high. Culms 
erect, slender, glabrous,, terete, simple below, then with a solitary long 
leafy branch and above it with a few distant erect solitary flowering 
branches. Leaf-sheaths terete, tight, glabrous, moderately firm, 
the lower and intermediate longer or only slightly shorter than the 
internodes, produced at the mouth into narrow acute auricles, up 
to 4 lin. long ; ligules membranous, laterally adnate to the auricles 
of the sheath ; blades very narrow from the base, long-tapering to 
a fine point, up to over 6 in. by 1-1 \ lin., flat or convolute, slightly 
rough or puberulous on both sides, midrib whitish, rather slender, 
rounded and prominent on the back, lateral nerves obscure ; sub- 
tending leaf with a somewhat tumid at length very narrow and 
tight sheath, with or without a setaceous rudimentary blade. 
Peduncles filiform, 4-6 in. long, straight, terminating with a minute 
glabrous or scantily bearded cupule. Eacemes 2-nate, one sessile, 
the other with a short base, 1J-2J in. long, straight, slightly villous ; 
joints and pedicels equal or subequal, linear-cuneate, very slender 
towards the base, up to over 2 lin. long, shortly ciliate on both sides, 
cilia \ lin. long, tips obliquely cupular, minutely toothed. Sessile 
spikelets of all pairs heterogamous (or the lowest of the sessile raceme 
more or less reduced or $ ), laterally much compressed, loosely wedged 
in between joint and pedicel, narrowly linear in front view, 3J lin. 
long, glabrous ; callus very short and minutely bearded. Glumes 
equal, lower subcoriaceous, dull green, with a deep narrow hyaline 
groove between the keels which are obtuse and smooth up to over 
three-quarters, then acute and subscaberulous, tips minutely 2- 
toothed, nerves 3 in each keel, a short fourth inside each keel ; upper 
glume boat-shaped, submembranous, 1-nerved, ciliolate with a 
terminal bristle up to 2 lin. long, rising from the sinus of 2 small 
hyaline teeth. Lower floret reduced to a narrow linear hyaline 
2-nerved ciliate valve. Upper floret ^ ; valve oblong, 2-fid with 
acute lobes, ciliate, awn very slender, f in. long, kneed at and 
scaberulous below the middle ; valvule an oblong hyaline scale, 1 lin. 
long. Anthers up to 2 lin. long. Pedicelled spikelet $ , dorsally 
compressed, oblong, acute, 2J-3 lin. long, pale brownish ; lower 
glume submembranous, with a terminal mucro or short bristle and
