A specimen received from Mr. Buijsman who grew it in his garden atLawang, 
Java, is evidently this species. It is noteworthy on account of its long 
prostrate-ascending base comprising 11 internodes and varying in length 
from 1 in. to 6 in. The lowest internodes are wiry and only ^ lin. in diameter, 
whilst the uppermost measure 2\ lin. across where the stem becomes 
upright. All the nodes emit roots, those from the ascending upper portions 
being very stout and strong and acting as stilt-roots. The lower and inter- 
mediate nodes produce at the same time extra-vaginal innovations with more 
or less white-villous or hirsute cataphylls or more rarely — like the upper 
nodes — intravaginal shoots.

Perennial, up to 4-5 ft. high, csespitose with few intravaginal inno- ' 
vations. Culms erect or ascending, rarely up to 2 lin. thick, 5-7- 
noded and simple below the panicle. Leaf-sheaths terete, quite 
glabrous, very rarely hirsute with short tubercle-based hairs, the 
basal firmer and more or less persistent ; ligules scarious, 1-2 lin. 
long, rounded ; blades linear from a slightly narrower or equally 
broad and somewhat constricted base, long-tapering to a fine point, 
to over 1 ft. long and 2-4 lin. wide, firm but hardly rigid, green or 
reddish or sub glaucous, glabrous, scabrid to spinulous along the 
margins, otherwise slightly rough or almost smooth ; midrib some- 
what slender and prominent below, whitish and often rather broad 
above ; primary lateral nerves 3-4 on each side, slightly raised. 
Spatheate panicle narrow, more or less lax, |-1J ft. long, of 6-8 
up to 5-rayed mostly mixed tiers, the internodes gradually decreasing 
in length upwards ; lower subtending leaves resembling the preceding 
ones, their blades usually shorter than the panicle ; upper much 
reduced, often reddish with small blades ; compound rays rarely 
more than 3-noded, ultimate simple rays filiform, J-1J in. Jong. 
Spatheoles permanently boat-shaped, lanceolate, acutely acuminate, 
§-H in. long, lj-lf lin. wide, thinly scarious, glabrous (very rarely 
hirsute) ; peduncles filiform, 8-9 lin. long, their tips together with the 
very short raceme-bases densely bearded, hairs up to 2 lin. long, 
white or yellowish. Racemes sessile or subsessile, subcontiguous, 
at length epinastically reflexed and exserted laterally from the 
spatheole together with the strongly arching peduncles, 5-7 lin. 
long, about 5-awned per pair ; joints filiform, obliquely truncate, 
up to almost 1 lin. long, shortly wbite-ciliate, uppermost cilia 
up to 1 lin. long; pedicels very similar. Homogamous pair of 
spikelets 1 at the base of the lower raceme only. Fertile 
spikeiets oblong, 2-2J lin. long, pale, sometimes reddish upwards 
or brown on the back, very sparingly or densely hairy ; callus 
hardly 1 lin. long, subacute, shortly bearded. Glumes equal,
