Spikelets 2-nate, one sessile, the other pedicelled, similar in shape 
or the pedicelled reduced and smaller, the latter always different in 
sex except sometimes the lowermost pair which may be homogamous 
( $ or neuter), on the fragile rhachis of many-jointed shortly peduncled 
subdigitate or panicled racemes ; joints and pedicels filiform, longi- 
tudinally grooved and hyaline in the groove, disarticulating hori- 
zontally ; sessile and pedicelled (always ?) spikelets deciduous, the 
former with the adjacent joint and pedicel. Florets 2 in the sessile 
spikelets, lower reduced to an empty valve, upper § , 2 or 1 in the 
pedicelled spikelet, the lower $ or neuter, the upper neuter or usually 
quite suppressed. Sessile spikelet dorsally compressed, awned ; 
callus small,, shortly bearded. Glumes equal, thinly chartaceous to 
membranous ; lower 2-keeled, with narrow sharply inflexed margins ; 
upper boat-shaped, 3-nerved, acutely keeled. Valve of lower floret 
hyaline, nerveless, of upper floret reduced to a hyaline linear stipe, 
firmer upwards, passing into a slender awn. Valvules 0 or very 
minute. Lodicules 2, minute, glabrous. Stamens 3. Stigmas 
exserted laterally usually low down, longer than the styles. Grain 
oblong, obtuse, dorsally slightly compressed ; embryo about half 
the length of the grain. Pedicelled spikelet awnless, valves (if present) 
hyaline, nerveless. — Perennial grasses with slender simple or branched 
culms, bearded or beardless at the nodes. Panicles mostly sub- 
digitate with a short primary axis, rarely the racemes on branches of 
the second order ; racemes always shortly peduncled. Spikelets small . 
Species probably over 25, mostly in tropical Asia, many of them closely 
allied and difficult to differentiate. 
Primary axis elongated, much longer than the lowest 
racemes (see also A. insculpta, var. vegetior )•; 
lower branches, or at least the strongest, sparingly 
divided, but not beyond the second degree ... 1. A. glabra. 
Primary axis short, much overtopped by the racemes. 
Lower glume of sessile spikelets typically pitless ... 2. A. radicans. 
Lower glume of sessile spikelets pitted or only some 
of a panicle without a pit. 
Pedicelled spikelets without pits ; sessile spikelets 
distinctly hairy below, not glossy, up to 2 lin. 
long, pale. 
Sessile spikelets linear- or lanceolate-oblong, 
tips very minutely truncate, often reddish ; 
pits small, often absent or present in the [acidula. 
same panicle ... ... ... ... 3. A. intermedia, var. 
Sessile spikelets oblong ; pits very conspicuous 
and deep ... ... ... ... ... 4. A. pertusa. 
Pedicelled spikelets with 1-3 pits ; sessile spike- 
lets glabrous, more or less glossy, often over 
2 lin. long, usually olive-green or flushed with 
purple or violet.. 5. A. insculpta.
