the old sheaths, simple, 2-4 ft. high, "glabrous or sparingly hairy below 
the inflorescence, 1-3-noded, the uppermost internode by far the 
longest. Leaves mostly crowded near the base ; lowest sheaths 
rather firm, strongly striate, appressedly hairy to densely silky- 
tomentose at the base, persistent, at length breaking up into fibres, 
the following usually glabrous except at the nodes which are either 
densely bearded or more rarely finely pubescent or very rarely quite 
glabrous, uppermost very long, rather loose ; ligules short or some- 
times up to 1J lin. long, scarious, obtuse or truncate, glabrous ; 
blades linear, tapering to a fine point, up to 9 in. (rarely more) by 1J-2 J 
lin., flat or with involute margins, firm, glabrous, flexuous, green, 
slightly rough above and on the margins, midrib slender, primary 
lateral nerves 3-4 on each side, prominent above. Racemes usually 
very numerous, gathered into an oblong-panicle 5-7 (rarely 9) in. 
long, simple or the lowest compound, solitary or fascicled on a scabrid 
or hirsute angular common axis of variable length (mostly exceeding 
the lower racemes), sessile or the lower bare at the base with traces 
of arrested spikelets, slender, straight or flexuous, erect or more or 
less spreading, 2-5 in. long, dense or more or less loose ; rhachis 
very slender, sometimes wavy, triquetrous, lin. wide, lateral 
angles scabrid or setosely ciliate, internodes up to 1J lin. long ; 
pedicels in fascicles of 3-6, unequal, the longest up to 1J lin. long, 
angular, scabrid and more or less copiously setose upwards, the 
uppermost setae usually equalling the spikelets. Spikelets oblong 
to ovate-oblong, subacute, jo~io (rarely ~j) lin. long, greyish- or 
brownish-green on. the flat, chestnut- to black-brown on the convex 
side, quite glabrous. Lower glume suppressed, very rarely repre- 
sented by a minute hyaline truncate scale ; upper a tightly appressed 
delicate hyaline scale, rotundate-ovate, very obtuse, nerveless or 
faintly 1-nerved, lin. long. Lower floret oblong, as long as the 
spikelet or slightly shorter, tightly appressed to the face of the upper 
floret, hyaline, 3-nerved, quite glabrous ; valvule a very delicate 
narrow scale up to J lin. long ; lodicules very minute. Upper floret 
corresponding in outline and size to the spikelet, chestnut-brown or 
at length almost black, somewhat shining, chartaceous, very tough ; 
valve with distant margins. Anthers up to J lin. long . — Panicum
