16. H. Barteri^ Stapf. Annual, up to 6 or even 8 ft. high. Culms 
erect, solitary or fascicled, slender, simple and 3-5-noded below the 
panicle. Leaf-sheaths terete, or the lower keeled upwards, glabrous 
and smooth ; ligules very short, truncate, ciliolate, glabrous ; blades 
narrowly linear from an equally wide or slightly attenuated base, 
up to 1 ft. by 1J-2 lin., long-tapering to a fine point, somewhat 
flaccid, glabrous or hairy behind the ligule, more or less rough all 
over the upper surface and scaberulous along the margins, midrib 
slender, lateral nerves close and fine, slightly prominent above. 
Spatheate panicle decompound, rather dense, of about 7 upwards 
approximate tiers, most of the rays of the primary tiers (except of 
the uppermost) compound, some of the lowest up to 4-noded and 
up to over J ft. long, with secondary and occasionally tertiary tiers, 
the majority 1-noded, bearing a fan-shaped frequently many- 
(15- or more-) rayed secondary tier, these fan-shaped tiers more or 
less imbricate, ultimate rays about J in. long, very slender ; lower 
subtending leaves similar to the preceding ones, the following 
spatheaceous with narrow reduced blades, or the uppermost spathe- 
oloid and up to over 3 in. long. Spatheoles very narrow, linear, 
long-tapering to a fine point, 1 J-lf , rarely 2, in. long, scarious, reddish, 
at length inrolled and almost subulate ; peduncles very finely fili- 
form, slightly flexuous or quite straight, finely scaberulous upwards, 
sometimes with a few very fine white hairs, permanently shorter (1-1 J 
in. long) than the spatheole. Racemes subparallel or the lower more 
or less spreading, never epinastically reflexed, rather loose, 4-5 lin. 
long, 2-awned per pair, greenish, one sessile, the other with a 
very finely filiform base, 2J-4J lin. long and glabrous, or very 
minutely puberulous above the homogamous spikelets, bases dis- 
articulating very obliquely, and tips subsubulate ; terminal pedicels
