the base, hairy on the sides ; valvule oblong, acuminate, as long 
as or slightly longer than the valve and then shortly exseited from 
the spikelet, the keels very narrowly but firmly winged upwards, the 
wings revolute in the acumen which is slightly incurved (that is 
curved towards the valve) and often forms a short horn-shaped hood ; 
anthers §-d lin. long. Upper floret oblong, subacute, white to 
yellowish, its apex sometimes loosely clasped by the hooded part 
of the valvule of the lower floret : valve and valvule crustaceous, 
smooth. Grain oblong, yellowish-green ; scutellum longer than half 
the grain.

6. E. filifolia, Stapf. Perennial, compactly csespitose, 1-1 \ ft. 
high ; innovations intra vaginal. Culms erect, quite simple, very 
slender, compressed at least downwards, 1-noded with the node far 
below the middle, glabrous and smooth. Leaves crowded at the 
base ; sheaths tight, striate, glabrous or more or less, but usually 
sparingly, hairy upwards, the basal long-persistent . forming tough 
tight coats around the leafy and the flowering shoots ; ligules a 
ciliolate rim; blades filiform, subterete, . or laterally slightly com- 
pressed, narrowly channelled on the face or more deeply sc (to beyond 
the middle) with one of the margins indexed, pithy in the centre, 
subacute, 3-9 in. long, J to almost \ lin. in diam., striate, more 
or less loosely hairy, particularly towards the base, hairs fine, white, 
springing from a minute tubercle. Inflorescence of 3-1 erect or 
oblique secund spiciform sessile racemes ; common axis filiform, 
up to \ in. long, glabrous or sparingly hairy at the insertion of the 
racemes. Racemes dense, up to f in. long, alternate, 2-seriate, 
more or less purple ; rhachis trigonous, straight or wavy, lin. 
wide, puberulous, scaberulous and more or less loosely white/ ciliate 
along the lateral angles, usually dark purple on the back, internodes 
f-1 lin. long ; pedicels solitary, extremely short, angular, scabrid, 
setulose below the subdiscoid tips. Spikelets contiguous, oblong, 
about If lin. long, more or less tinged with purple, hairy. Glumes 
slightly unequal, quite or in part purple ; lower oblong, subobtuse, 
with minutely denticulate tips, about three-quarters the length of 
the spikelet, membranous, strongly 9 -nerved, sparingly hairy along 
the sides ; upper slightly longer than or as long as the spikelet, 
broad-lanceolate or oblong, subobtuse, 5-6-nerved with few cross- 
veins, loosely white hairy all over. Lower floret $ or neuter : valve 
oblong, acute or subacuminate, as long as the spikelet, similar in 
texture and colouring to the upper glume, 5-nerved with the inner 
side-nerves distant from the midnerve and connected by cross- 
veins, loosely hairy ; valvule lanceolate-oblong, somewhat shorter
