32. A. perligulatus, Stapf in Kew Bulletin, 1908, 410. Perennial, 
up to over 3 ft. high. Culms slender, at least 3-4-noded, terete, 
glabrous, smooth. Leaf-sheaths terete, glabrous or more or less 
hirsute upwards, glaucous, produced at the mouth into lanceolate 
acute auricles up to over 6 lin. long ; ligules scarious, as long as and 
adnate to the auricles of the sheath ; blades linear, long and narrowly 
attenuated towards the base and there generally much longer than 
the sheath, long-tapering to a fine point, up to over 1 ft. long and 
2 lin. wide, firm, rigid, glabrous or loosely hairy, particularly below, 
rough all over or smooth on the upper surface towards the base, 
midrib whitish, rather stout and prominent downwards, primary 
lateral nerves 2-3, raised above, obscure below. Inflorescence a 
very scanty spatheate panicle, up to 2J ft. long, of up to 4 very 
distant 2-rayed tiers, or the lowest branch undivided at the base ; 
spathes like the preceding leaves, the lower with well developed 
blades ; rays often very unequal, the primary often up to over 
1 ft. long, filiform, erect, strict. Spatheoles linear-lanceolate, 3-4 
in. long, passing into a short to very short subulate or setaceous 
rudimentary blade, subherbaceous to scarious, greenish or very 
slightly tinged with red or brown, glabrous, at length more or less 
tightly inrolled ; peduncle terminally shortly exserted. Racemes 2- 
nate, one sessile, the other with a very short base, slender, flexuous, 
up to 3 in. long, tinged with purple or violet, conspicuously dorsi- 
ventral, one side exhibiting the grooved sessile spikelets with the 
joints and the pedicelled spikelets in profile and the other the backs 
of the pedicelled spikelets and between them the broad backs of the 
upper glumes ; joints and pedicels broad-linear to cuneate-linear, 
1} lin. long, shortly ciliate, glossy, tips obliquely truncate, obscurely 
concave. Sessile spikelets heterogamous or of the lowest pair of the 
sessile raceme homogamous or imperfect, wedged in between the joint 
and pedicel, laterally much compressed, linear in front view, 2 j lin. 
long, glabrous, yellowish, reddish or brownish at the tips ; callus 
short, very shortly bearded. Glumes equal, the lower subcoriaceous, 
minutely truncate, with a deep and narrow groove between the keels 
which are smooth up to two-thirds and then spinulously ciliate, 
one nerve on each side of the groove, 2-3 in or close to the keels ; 
upper glume boat-shaped with a broad rounded back below and a 
scaberulous keel upwards, 3-nerved, margins narrow, hyaline, ciliolate. 
Lower floret reduced to an oblong 2-nerved hyaline ciliolate valve, 
slightly shorter than the glumes. Upper floret ^ : valve broad-oblong,
