yc phylls ovate to lanceolate, acute, hard, smooth. Culms erect or 
more often shortly ascending, up to over 3 ft. high ; rather slender, 
glabrous, many-noded, mostly producing short leaf -branches from 
the lower and intermediate nodes. Leaf-sheaths terete, rarely 
slightly compressed, quite glabrous or sometimes pubescent at the

truncate, very short, firmly scarious ; blades linear, long-tapering 
to a setaceous point, hardly broader and slightly contracted at the 
base, 3-8 in. by 1-2 \ lin., pale green or glaucescent or turning red- 
dish, glabrous apart from usually scanty very fine spreading white 
hairs at and above the ligule, smooth except at the tips, midrib promi- 
nent, lateral nerves 3-4 on each side. Panicle subdigitate, obovoid, 
2-3 in. long ; primary axis up to 2 in. long, filiform, glabrous, rarely 
obscurely bearded in the branch axils; lower branches * opposite, 
upper or uppermost alternate, rarely all alternate, straight, undivided 
or the lowermost bearing 2 (rarely 3 or 4) racemes. Racemes 10-15 
or sometimes more, 1-2 in. long, often flexuous, pale or purplish, 
white-villous ; joints and pedicels 1-1 J lin. long, ciliate, cilia in- 
creasing from the middle upwards, the uppermost 1J (rarely 2) lin. 
long. Sessile spikelet linear- or lanceolate- oblong, pale with reddish 
tips or more or less purplish all over, including the small minutely 
bearded obtuse callus about If lin. long. Glumes equal ; lower

upwards, intracarinal nerves 4-5, very fine and obscure or distinct 
upwards, with or without a pit above the middle ; upper glume 
lanceolate, acute or mucronulate, obscurely 1-3-nerved, keel scabrid 
above, margins sparingly ciliate. Valve of lower floret linear- 
oblong, subacute, If lin. long, hyaline, nerveless, ciliate, awn of 
upper floret, including the stipe 4J-6 lin. long, pale brown below 
and whitish above the centre. Anthers f lin. long. Pedicelled 
spikelet neuter, rarely imperfectly $ , narrowly oblong, IJ-lf lin. 
long, glabrous, of the same colour as the sessile. Glumes equal or
