lower 1J-1J lirn long, 5-nerved, tlie upper lf-2 lin. long, 7-9-nerved. 
Lower floret : valve obliquely and broadly oblong in profile, shortly 
and acutely acuminate, 3J-3J lin. long, thinly chartaceous. Upper 
floret : valve oblong-lanceolate in profile, subulate- acuminate, with 
the acumen slightly incurved, glabrous and smooth except at the 
minutely pubescent or villosulous base and the finely villosulous 
margins of the beak. Anthers 2 lin. long. Stigmas exserted sub- 
terminally, pale, J lin. long.

4. M. glaber, Stapf. Quite glabrous except at the base of the 
lowest cataphylls. Culms up to over 2 lin. in diam., striate, her- 
baceous, branching by means of extravaginal buds which break 
through the back of the base of the sheath of the lowest perfect 
foliage leaf, are covered with about 3 cataphylls, root from the basal 
nodes and grow out into secondary more or less erect leafy flowering 
culms ; lowest cataphyll very short, rounded, second about 1 in. 
long, wide, like the preceding appressedly hairy at the base, otherwise 
glabrous, all distinctly striate. Perfect foliage leaves 1-4 with 
each culm; sheaths tight, striate, quite glabrous between the ribs, 
along the margins, and on the dorsal rim at the junction with the 
blade ; ligules a subcoriaceous glabrous rim ; blades obliquely 
broad-lanceolate, sometimes subfalcate, tapering from the lowest 
third or quarter upwards, rapidly contracted towards the almost 
petioloid base, about 9 in. by 2-3 in., rather firm, quite glabrous, 
midrib prominent below, lateral nerves 30-50 per inch ; epidermal 
Cells slightly wider than long, otherwise almost as in M . Aspidistrula. 
Inflorescence at length long- (by up to 4 in.) exserted, about 7-8 in. 
long ; lower and intermediate primary branches 1|-1 in. apart, up 
to 4 in. long, with numerous partly arrested spikelets ; axes filiform, 
the primary somewhat stout, all very angular and very finely 
scaberulous ; pedicels very unequal, up to 2 lin. or the terminal up 
to 4 lin. long, scaberulous, tips obscurely discoid. Spikelets 3|-4 
lin. long, very like those of M. Aspiaistrula , whitish. — iff. Aspidistrula,

Spikelets obliquely ovoid, laterally compressed and mostly con- 
spicuously gaping, falling entire from the pedicels, 2-nate or more 
often subsolitary (the secondary of the pair more or less arrested) 
or solitary, secund on the flat or subtriquetrous slender rhachis of 
spiciform racemosely arranged racemes ; lower floret $ or barren ;
