CL VII. GRAMINEJE (Stapf). 
[Entolasia. 
slightly flexuous, glabrous ; common axis slender, angular, com- 
pressed and scaberulous upwards, internodes irregularly long (up to 
14 in.) and short ; primary branches erect, solitary, up to over 3 in. 
long, the longest undivided up to and even 2 in. from the base, 
or with some quite rudimentary spikelets low down, slender, sub- 
flexuous, triquetrous with marginate scabrid angles, the lower bearing 
at the base secondary branches, otherwise like all the upper branches 
simple ; all the branches and branchlets forming dense secund 
spiciform racemes. Rhcemes § to over 1 in. long ; rhachis trique- 
trous, scabrid, often wavy, internodes J-l lin. long ; pedicels very 
short, somewhat stout with scabrid angles or reduced to mere stumps, 
with truncate slightly cupular tips. Spikelets imbricate, 2-ranked, 
lanceolate-oblong, acute, dorsally rather markedly compressed, 
2 J-24 lin. long, very pale. Lower glume much wider than high, obtuse, 
about one-fifteenth the length of the spikelet, hyaline, nerveless ; 
upper glume faintly 5-nerved in transmitted light, otherwise 
apparently nerveless. Lower floret reduced to a valve exactly like 
the upper glume. Upper floret oblong, obtuse, 2 lin. long, pale ; 
valve papery, delicately hairy, very faintly 5-nerved, with narrowly 
involute margins ; valvule similar in substance, the lateral keels 
sharply set off from the thinner back, passing on the other side 
gradually into the blunt indexed flaps ; anthers lin. long.

2. E. olivacea, Stapf Perennial, up to 2-3 ft. high, with a 
decumbent copiously rooting and apparently early disintegrating 
base. Culms erect, geniculate (sometimes repeatedly), branched, 
many-noded, internodes shorter than the sheaths or at length usually 
more or less exserted from them, terete, striate, glabrous. Leaf- 
sheaths rather tight, terete, "slightly keeled upwards, more or less 
subherbaceous, prominently striate, slightly and minutely hairy at 
the nodes and with a transverse dorsal fringe of hairs at the junction 
with the blade, otherwise quite glabrous and smooth or, rarely, with 
some stiff minutely tubercle-based hairs ; ligule a densely ciliate 
rim ; blades linear-lanceolate from a suddenly constricted and 
rounded base, very acutely acuminate, 3-54 in. by 4-6 lin., flat, 
papery, glabrous and smooth except along the cartilaginous scabrid 
and on one side markedly crisped margins, midrib not or indistinctly 
differentiated on the face, very slender but prominent on the back, 
primary lateral nerves about 4 on each side, mostly faint with equally 
faint secondary nerves and short transverse veins in the intervals. 
Panicles terminal, 5-6 in. long, contracted or (temporarily ?) wide 
open, somewhat flexuous, glabrous ; common axis very slender, 
terete and smooth below, angular and scaberulous above, internodes 
in. long ; primary branches erect or (temporarily ?) widely spread- 
ing, solitary or here and there 2-nate, up to over 3 in. (lower) or
