6. ANDR0PTERUM, Stapf. 
Spikelets 2-nate, those of each pair different in , sex and shape, one 
sessile, the other pedicelled on the articulate fragile rhachis of solitary 
spike-like racemes, the sessile deciduous together with the adjacent 
joint and pedicelled spikelet. Florets 2 ; lower 8? upper $ in the 
sessile, $ in the pedicelled spikelets. Sessile spikelets : Glumes some- 
what unequal, subchartaceous ; lower deeply grooved, subentire or 2- 
toothed, subchartaceous, 2-keeled with infiexed margins, keels wing- 
less ; upper glume boat-shaped, keeled upwards, with the keel pro- 
duced into an obtuse erect wing, adnate to a short mucro. Valves 
hyaline, of lower floret entire, muticous, of upper 2-fid and awned 
from the sinus. Valvules slightly shorter than the valves, hyaline. 
Lodicules 2, cuneate. Stamens 3. Stigmas linear-oblong, laterally 
exserted. Grain unknown. Pedicelled spikelets obtuse : lower 
glume very asymmetrical, narrowly infiexed on one side only, with 
a large wing from the keel curving over sideways, upper boat-shaped, 
laterally much compressed ; florets subequal, — Probably peren- 
nial ; leaf-blades flat, slightly constricted at the base ; ligule a line 
of stiff hairs ; racemes dorsiventral much compressed with the 
pedicelled spikelets distichously arranged, the latter very conspicuous 
on account of the large wings which are rolled back over the posticous 
side of the lower glume. 
Species 1, endemic. 
1. A. variegatum, Stapf. Culms erect, over 2 ft. high, rather 
slender, terete, simple or more often branched from below with the 
branches appressed ; internodes more or less exserted, glabrous or
