stout, 10 to 14 ft. (or more) high, 20-30-noded. Leaf-sheaths 
minutely pubescent at the nodes ; ligules very short, densely ciliate 
from the back ; blades linear-lanceolate, over 1 ft. by 2| in., pale 
green, pubescent to tomentose inside above the ligule and outside 
at the junction with the sheath. Panicle erect or recurved, ovoid 
to oblong, very compact or somewhat loose, 4-10 in. by 2-3 in. ; 
branches rather stout below, rigid, spinulously ciliolate, particularly 
upwards, softly ciliate to villous at the base, branches divided almost 
from the base, the longest 2-3 in. long. Racemes compact, up to 
3- or 4-noded, up to 5 (rarely 6) lin. long ; joints rather stout, com- 
pressed, \ lin. long, more or less white-silky-villous ; pedicels very 
similar, of about the same length. Sessile spikelet ovate with 
rather broad tips, 2f lin. by IJ-lf lin., pale straw-colour with greenish 
tips, whitish when mature, awned. Glumes equal, coriaceous about 
up to the middle or at the base only, otherwise papery and often 
partly spongy, white-silky-villous all over or glabrous on the coria- 
ceous portion of the back ; lower 12-nerved (with the nerves distinct 
upwards and sometimes with a few very delicate additional nerves 
interspersed), sharply 2-keeled upwards with the keels spinulously 
ciliolate and abruptly ending, forming minute teeth between which 
the hyaline end of the tip protrudes ; upper very broad, about 12- 
nerved, slightly keeled upwards. Valves very densely ciliate ; upper 
broad elliptic-oblong ; lower broad-ovate, 2-lobed, 2 lin. long ; awn 
about 4 lin. long with the bristle half the length of the long-exserted 
column or more or less reduced. Anthers 1J lin. long. Grain 
equalling the glumes or more or less exserted, orbicular or orbicular - 
obovate in outline, more or less (often much) compressed, 2-2 j- lin.
