Trachypogon .] clvii. gramine^e (Stapf). 407 
tip, or cartilaginous upwards with a short twisted bristle. Anthers 
2 lin. long. Fertile spikelets linear, 4-4J lin. long, including the 
subacute densely bearded callus which is f lin. long. Glumes sub- 
equal ; lower convolute, chartaceous, truncate, obscurely ciliolate 
near the scarious tip, villosulous all over, intracarinal nerves 5 almost 
without transverse veins ; upper very slightly longer, linear, subacute 
to almost obtuse, ciliolate upwards. Lower floret reduced to a 
linear-oblong truncate ciliolate 2-nerved hyaline valve as long as the 
lower glume. Upper floret ^ : valve linear, hyaline and 3-nerved 
towards the base, cartilaginous upwards, passing into a slender 
flexuous subgeniculate silvery-grey awn, up to 2J in. long, column 
with few very steep spirals so tightly screwed up as to look almost 
solid, subplumose downwards, hairs up to J lin. long, bristle very 
shortly hairy all along.

48a. ELYMANDRA, Stapf. 
Spikelets 2-nate, those of the uppermost pair differing in sex and 
shape (forming with the pedicelled terminal spikelet a trio), those of 
the lower 5-6 pairs homogamous (alike in shape), one sessile, the 
other pedicelled on the rhachis of paired racemes, terminating the 
culms and their branches ; homogamous pairs loosely disposed on 
the axis which is almost tough between them, but disarticulates 
readily above them. Raceme-pairs supported by a spatheole, 
collected into very loose and usually scanty spatheate panicles ; 
the fertile spikelet falling with the adjacent pedicels ; joints and 
pedicels of the homogamous pairs stoutly linear, glabrous or almost 
so, except at the ciliolate nodes of the axis (raceme-base) ; pedicels 
of the terminal trio very slender, ciliate. Florets 2, lower reduced 
to an empty valve, upper $ in the sessile spikelet of the trio, rarely 
neuter, in all the others. Fertile spikelets subterete, awned ; callus 
moderately long, acute, shortly bearded. Glumes subequal, 
coriaceous, the lower quite keelless with an obtuse or truncate 
obscurely nerved tip, the upper acute, with a groove on each side of 
the rounded back, 3-nerved. Valves of lower floret hyaline, 2-nerved, 
of upper stipitiform with a long stout awn from between 2 short 
hyaline teeth. Valvule 0 Lodicules glabrous, small. Stamens 3. 
Stigmas laterally exserted ; styles terminal. Grain unknown. 
Pedicelled spikelets (of all pairs) and homogamous sessile spikelets 
lanceolate, acuminate, the lower mucronate to aristulate : lower 
glume keelless with the margins narrowly involute. Valves of both 
florets developed or the upper suppressed. — An annual, somewhat 
coarse grass. 
Species 1, endemic.
