most rapidly decreasing ; lower tiers consisting of few mostly 
compound rays, the longest almost up to 1 ft. long, few-noded, 
bearing secondanr tiers only, upper of 4-6, rarely more, mostly 
simple tiers, ultimate rays 1-| in. long, slender, filiform ; lowest 
subtending leaves like the preceding ones, the following spathaceous 
with upwards rapidly decreasing very narrow blades. Spatheoles 
narrowly lanceolate, long-acuminate, mostly from 2-3 in. by 1--1J 
lin., scarious, dull purple or reddish, glabrous, rarely more or less 
softly hairy, at length loosely inrolled from the margins and rather 
narrow ; peduncles filiform, from less than 1 in. to 1 J rarely 
2 in. long, very slightly curved or almost straight and hardly ex- 
serted from the spatheole, finely hairy towards the tips, hairs soft, 
not spreading. Racemes subcontiguous, laterally exserted from 
the spatheole, suberect and rarely nodding, never recurved or epin- 
astically reflexed, up to over i in. long, 2-awned per pair, the 
lower subsessile, the upper with a filiform glabrous or subglabrous 
base up to 1J lin. long, both bases produced into a thin scarious 
oblanceolate or linear upwards denticulate whitish appendage 
2J-4 lin. long ; pedicels slender, filiform, 2 lin. long, very shortly 
ciliate. Homogamous pair of spikelets 1 at the base of the 
lower raceme only. Fertile spikelets oblong, excluding the callus 
3J lin. long, almost terete in cross section, greenish, glabrous ; 
callus very slender and acute, up to 24 lin. long, shortly bearded. 
Glumes subcoriaceous, lower 2-dentate or 2-mucronate, slightly 
flattened on the back with a narrow very pronounced groove pro- 
jecting as a slender ridge on the inner side, 10-nerved, the 2 innermost 
nerves very close, lining the groove, like the others only visible by 
transmitted light, keels very short, like the tips scaberulous ; upper 
glume oblong, shortly 2-lobed with or without a mucro or bristle 
(up to over 1 lin. long) from the sinus. Lower floret reduced to 
a narrow linear-oblong 2-nerved ciliate hyaline valve, 2| to almost 
3 lin. long. Upper floret ^ : valve stipitiform, minutely 2-dentate, 
ciliate, awn mostly 3 in. (rarely only 2, or up to over 3| in.) long, 
very shortly fulvously hirtellous. Valvule 0. Pedicelled spikelets 
(J, subulate-lanceolate to linear-lanceolate, 6 lin. long, glabrous, 
pale green or faintly tinged with red or purple ; lower glume sub- 
herbaceous, with or without a terminal bristle (up to 3 lin. long), 
11-nerved, keels rigidly ciliolate upwards ; upper membranous, 
very acute, 3-nerved, spreadingly ciliate : valves hyaline, narrowly 
linear-oblong, ciliate, 5 lin. long, the lower 3-, the upper 1 -nerved ; 
anthers 2 J lin. long. Homogamous spikelets similar to the 
pedicelled, but muticous. — Andropogon arundinaceus , Benth. in
