CLVIl. GRAMINEJE (Stapf). 
[. Anadelphia . 
Peduncles very short (3 lin. long when in 
flower) ; panicle narrow and stiff, all the 
tiers distant and scanty ; racemes with 
3-5 sessile spikelets ; awn very delicate, 
concolorous, 5 lin. long ; upper leaf-blades 
very long and narrow ... ... ... 4. A. long i folia. 
Sessile spikelets pubescent ; simple rays 48-24 lin. 
long, the outermost of some tiers frequently 
barren, with crowded short normal leaves, 
hence the panicle interspersed with leaf -tufts 
(anomalous?) ... ... ... ... ... 5. A. pubiglumis. ^ 
f f Sessile spikelets 2^-4 lin., pedicelled 3|~6 lin. long ; 
awn of fertile floret 8-21 lin. long ; racemes 
always with 2 sessile and 3 pedicelled spikelets. 
Peduncle as long as to much longer than the spa- 
theole ; awn about 8 lin. long with an 
abruptly deflexed bristle ... 6. A. Jiamata. 
Peduncle very much shorter (2-3| lin. long) than 
and permanently enclosed, in the spatheole ; 
awns 1-2 in. long. 
Sparingly hairy to glabrous ; the awned valve 
shortly 2-lobed or 2-toothed ... ... 7. A. arrecta. ^ 
Very hairy all over ; the awned valve 2-fid to 
the middle 8. A. afzeliana . \/ 
**Upper glume of sessile spikelet without a bristle, 3-den- 
tate ; awn 3 in. long ; racemes with 7 sessile and 
2 pedicelled spikelets ... ... 9. A. trispieulata. 
1. A. trepidaria^ Stapf. Perennial (?). Culms slender, terete or 
somewhat compressed near the base, 3-noded below the panicle. 
Leaf-sheaths tight, finely striate, gradually passing into the blades, 
up to over 1 in. long, the lower purplish ; ligules very short, rounded, 
ciliolate ; blades narrowly linear, long-tapering to a setaceous point, 
1J-5 in. long, \ lin. wide, flaccid, flat or involute, minutely papillose 
near the base, otherwise glabrous, smooth below, midrib wide and 
whitish above, very slender and prominent below, primary lateral 
nerves 2 on each side, very fine. Spatheate panicle loose, decom- 
pound to the third degree, J-l ft. by 2-4 in. or more or less reduced 
and then usually narrow ; primary internodes up to 7 or 8, lowest 
about 3J in. long, the following gradually decreasing ; primary tiers 
up to 5-rayed, their rays very unequal and (except those of the 
uppermost) usually all compound, the longest of the lower tiers up 
to over 6 in. long, flexuous to flaccid, with up to 7 secondary mixed 
4- or f ewer-rayed tiers, their compound rays bearing 3-1 tertiary 
tiers of up to 4 simple rays ; ultimate (simple) rays subcapillary, 
6-3 lin. long, asperulous ; lower subtending leaves like the pre- 
ceding ones with subfiliform blades often 4-6 in. long, the upper 
with very narrow spathaceous sheaths and rapidly reduced or 
(the uppermost) suppressed blades. Spatheoles very narrow, 
scarious, J-f- in. long, pale brown or purplish, usually with a few 
long fine tubercle-based hairs ; peduncles at length up to 4 lin. long, 
enclosed in the spathe or their tips laterally exserted, scaberulous,
