28. B. serrata .Stapf. Perennial, up to 2 ft. high, more or less 
densely tufted ; rhizome short, thick, with stout densely tomentose 
root-fibres ; innovations extravaginal, covered with densely tomen- 
tose or villous cataphylls, growing up erect and often closely packed, 
rarely lengthening out into short stolons. Culms usually erect, 
terete, rather slender, branched from the base and some of the lower 
nodes, rarely geniculatelv ascending , lower and intermediate inter- 
nodes 4-5, rarely more, wholly enclosed in their sheaths oi nearly so, 
hairy, short or at any rate very much shorter than the long-exserted 
glabrous uppermost internode. Leaves usually crowded towards 
the base ; sheaths tight, firm, the upper more or less herbaceous, 
glabrous except near the mouth, along the outer margin and at the 
villous nodes, or like the lower more or less hairy, the latter often 
softly and shortly hirsute ; ligules a transverse fringe of short hairs ; 
blades linear to lanceolate-linear, long-tapering to a callous point, 
1-5 in. by l|-4 lin., flat or convolute, rigid, stout, glabrous or more or 
less hairy, sometimes densely so, margins cartilaginous, often closely 
crisped or wavy, minutely spinulose, nerves numerous, slender and 
close, the midrib and 3-5 primary lateral nerves distinctly differenti- 
ated below only if at all. Inflorescence very narrow, of 3-10 suberect 
or appressed spike-like racemes ; common axis filiform, 3 (rarely more) 
in. long, more or less semiterete, glabrous or puberulous or pubescent. 
Racemes usually longer than the internodes, the lowest |--| rarely 
1 in. long, the following gradually shorter or all very short, sessile 
or the lowest shortly peduncled, 2-seriate, simple, rarely with a 
small secondary raceme at the base, secund ; rhachis filiform, trique- 
trous, up to J lin. wide, angular, wavy, pubescent with or without 
longer fine hairs, internodes about \ lin. long ; pedicels solitary or 
the lower 2-nate, filiform with discoid tips, very short, rarely the 
longer of a pair over J lin. long, pubescent, usually with some long 
fine hairs upwards. Spikelets laterally contiguous or subimbricate, 
ovoid-ellipsoid to ellipsoid, shortly subacute and cuspidulate, or 
obtuse, turgid, 1J-1J lin. long, pallid, overtopped by a purplish tuft 
of hairs. Glumes very unequal ; lower subhyaline, broad-ovate, 
obtuse, more than half the length, of the spikelet, 3-nerved, often 
dark purple, pubescent ; upper glume corresponding in outline and 
size to the spikelet, very convex, membranous, pale or greenish,
