Stenotaphrum .] clvii. gramine^j (Stapf). 
marginate and herbaceousiy winged, with the wing produced into a 
short or long lanceolate acute tooth or lobe, or both lateral angles 
winged but with the wings alternately narrower and wider and the 
latter only toothed or lobed or (lowest internodes) only marginate, 
margins scabrid, the whole rhachis therefore when seen from the 
back ribbon-like, alternately lobed or toothed or entire downwards, 
1-2J lin. wide, and, seen from the face, more or less distinctly 
chambered, the chambers alternately to the right and the left of the 
midrib. Racemes sessile, sunk in the chambers or shortly exserted 
from them, mostly 3-5- (rarely 2- or 6-8-)spiculate, 2J-5 (rarely 6) 
lin. long, distant by their own or less than their own length or the 
lowest remote ; rhachis wavy or zig-zag, ending in a subulate point, 
triquetrous, flattened, with the lateral angles marginate or more or 
less winged downwards, internodes less than 1 lin. long, glabrous or 
more or less ciliate downwards ; pedicels reduced to very short 
sometimes ciliate stumps. Spikelets if more than 3 more or less 
2rseriate and laterally contiguous or imbricate, lanceolate-oblong, 
subacuminate to acutely acuminate, 2-2J lin. long, pallid. Glumes 
very dissimilar ; lower a whiti sh nerveless membranous to chartaceous 
ovate obtuse or rounded scale, J-f lin. long, finely asperulous and 
more or less ciliolate on the top ; upper glume very convex to boat- 
shaped, semi-ovate or semi-elliptic in profile, acute, usually slightly 
shorter than the spikelet, membranous, typically 7-, but sometimes 
up to 9- and even 11-nerved, glabrous or ciliolate towards the tip. 
Lower floret g : valve corresponding in outline and size to the 
spikelet as seen from the front, more or less coriaceous, often very 
much so, and then the 5 (rarely 7) nerves very obscure or invisible 
except in the acumen, glabrous or ciliolate near the tip ; valvule 
somewhat shorter than the valve. Upper floret ^ , as long as the 
lower or very slightly shorter ; valve and valvule lanceolate, acute 
or acuminate, thinly chartaceous, smooth, glabrous or more or less 
ciliolate upwards, the former 5-nerved, the latter 2-nerved with 
rounded sides ; stigmas rather large. — Nees, El. Afr. Austr. 63 ;
