9. B. brevis, Staff. Perennial, b- 1 J ft. high, densely caespitose 
with intra- and extra vagina] innovations, the cataphylls of the 
former glabrous. Culms erect or geniculately ascending, mostly 
2-noded, terete or compressed below, simple or sparingly branched 
at the base ; internodes glabrous or slightly hairy below the nodes. 
Leaf -sheaths tight (the lower) or more or less loose and herbaceous 
(the upper), the basal rather firm, persistent, turning brown, often 
ciliate on the outer margin, otherwise glabrous or beset with scattered 
fine tubercle-based hairs ; ligules a narrow ciliate rim. Blades 
linear-lanceolate to linear from an equally wide or slightly rounded 
base, tapering to an acute point, 1 J-7 in. by 2-2J lin., flat, dud green, 
moderately firm, glabrous except for the margins which are more 
or less ciliate at least towards the base and scabrid or minutely 
spinulose ; midrib very slender like the primary lateral nerves 
(3-4 on each side). Inflorescence erect, secund, of 6-10 about equally 
distant suberect or spreading straight or arching dense secund 
spike-like racemes ; common axis 2-4 in. long, slender, subtrique- 
trous, glabrous. Racemes 2-seriate or 1-seriate by the dovetailing 
of the ranks, 1-J-J in. long, simple, greenish ; rhachis subherbaceous, 
flat, about J-J lin. wide, with a prominent slender zig-zag midrib, 
very finely pubescent on both sides, ciliate along the margins, cilia 
very fine, mostly under 1 lin. long ; internodes almost b lin. long ; 
pedicels extremely short with subdiscoid tips and some long yellowish 
hairs. Spikelets contiguous or imbricate, about 1J lin. long, more 
or less hairy. Glumes membranous ; lower broad-elliptic, very 
obtuse or emarginate, glabrous, 7-9-nerved, two-thirds to three- 
quarters the length of the spikelet ; upper glume corresponding in 
outline and size to the spikelet, shortly and finely hairy upwards, 
5-nerved with distant cross-veins from low down or from the middle 
upwards. Lower floret as long as the spikelet ; valve similar to 
the upper glume, but hairy on the sides only, with the lateral nerves 
submarginal, the cross veins confined to the upper part. Upper 
floret as in B.falcifera if not slightly smaller.

10. B. soluta, Staff. Perennial, loosely caespitose, up to over 
2 ft. high, from a very slender rhizome with extra vaginal innova- 
tions which grow sometimes into short creeping stolons and are 
covered with glabrous cataphylls. Culms very slender, often 
geniculately ascending, 5-6-noded, compressed below, more or
