narrow callus aud produced beyond the base of the petiole to meet tlie ligule; ligule
broad, cleft. Inflorescence a teraiinal panicle of spieate brancblets, bearing distant heads
•with a few very large flattened spikelets; heads 1 to 3 in. apart with 1 to 4 spikclets
and very small bracts, racliis smooth, stiiate. Spikelets 1-2 in. long, -3 to -4 in. broad,
compressed; empty glumes 2 to 3, lower with a separate imperfect blade, ovate-lanceolatc,
mucronate, many-veined, glabrous; floive/s about 7 to 9 with 1 or 2 terminal nnperfect
ones; flowering glume ovate-lanceolate, long-acuminate, shghtly ciliatc on the edges and
h a i r y witliin; palea shorter than floweiing glume, 2-keeled, 7-nerved, ciliate on the keels,
blunt. Lodicules small, obovate, 3—5-nerved, fimbriately ciliate. Stamens esserted, tube
thickened at first, afterwards very fragile, membranous; anihcis narrow, penicillato
apiculate. Ovary narrowly ovoid, pubescent, narrowed into a slender style wliich is
divided above into 3 plumose stigmas.

This has more the appearance of Bcimbusa than of Giganfochloa, but the monadelphous
stamens are conclusive. It comes very near to G. heterostachya, but the spikelets ai-e
larger and compressed. It is said to be used for basket-making and to be called Bulu
tildn miniak. It is at once recognised by the very largo flattened spikelets.

Ai-borescent or scandent bamboos, usually of medium or small size, unai-med, often
gregarious. Culms from a thick rhizome, usually creeping underground and stoloniferous;
atbn-sheaihs various, usually rather narrow, the imperfect blade also narrow. .Leaves
variable, but generally small, shortly petiolate, as in Bamlusa. Inflorescence a large panicle
•with spieate heads of few or many spikelets. Spikelets narrow, elongate, conical, bearing
1 2 or 3 flowers, the uppermost usually fertile. Empty glumes 1 to 3, flowering glumes
oTOte, elongated, mucronate. Palea of lower flowers 2-kceled, of uppermost flower convolute,
only little or not at all keeled. Lodicules none. Stamens monadelphous, exserted,
tube thickened at fii-st, afterwards membranaceous, elongate; anthers narrow, acute or
apiculate. Ovary ovoid, style fine, stigmas 1 to 3, usually more or less plumose.
Caryopsis elongate, terminated by a beak foi-med by the pex-sistcnt style base, grooved,
embiyo conspicuous.

An evergreen tufted bamboo. Ctilms 30 to 40 f t . high, 'ó to 2 in. in diameter, usually
dark green, sometimes marked with longitudinal yellow stripes; nodes prominent; iuternodes
scabrous, rough above. Ctilm-sheaths about C in. long, stiiate, ciliate at the edges, covered
on the back with appressed stiS brown hairs, slightly narrowed upwards, truncate at the toj);
imperfect bhde ovate-lanceolate, decurrent on the sheath, and furnished on either side with a
bright green, rounded, naked amide, haiiy within; ligule narrow, faintly toothed. Leaves
6 to 12 in. or more long, 1 to 2 in. broad, lanceolate; unequally rounded at the base or
attenuate into a "2 to '3 in. petiole; ending above in a subiilate twisted jwint; somewhat
rough above, pale and smooth and at first pubescent beneath, scabrous on one margin;
main vein proniinent, secondary veins 9 to 12, inconspicuous, transverse veinlets none,
but pellucid glands wliich appear beneath like transverse veinlets; leaf-sheaths stiff, hairy
at first, afterwards smooth, ciliate at the edges, produced at the mouth and furnished
•with small, naked, rounded auricles ; ligule narrow. Inflorescence a large compressed,
sometimes leafy, panicle of spieate verticils ; racliis pubescent especially above, striate,
1 to 3 in. between verticils; spikelets usually few in the verticils. Spikelets narrow,
cyHndric, 1 in. long by "1 to '2 in. in diameter, conspicuously black- or purple-fringed
at the edges of the glmnes, sometimes cmwed; bearing empty glumes 2 to 3, fertile
fiowers 2 to 3, and a terminal imperfect flower; empty glumes ovate-acute, mucronate,
ciliate on the edges, many-veined; flowering glume lanceolate, acuminate, long-mucronate,
ciliate on the upper margnis, many-veined; palea shorter than, or as long as, the
flowering glume, narrow, obtuse or acute or bimucronate, 2-keel6d, ciliate on the keels
and 2- to 3-veined between them, that of uppermost flower convex, glabrous. Stamens
exserted, tube at first thick, aftei-^'ards elongated, membranous ; anthers -3 to '4 in. long,
narrow, purple, ending in a long hirsute point. Ovary nan-owly ovoid, acuminate, pubescent,

Sumatra and Java. Said also to occur in Coorg and Ganara, but this rcquii-es
further investigation: the specimens -were collectcd by Hohenacker and by no one
else. Collected by Heifer in Tenassexim; also by Falconer in 1849; also by G. King
on Pagoda Hill, Moulmcin, in 1879; by Kurz in S. Andaman, and by A. L. Home
in the Andamana in Z875; by myself in Kasalong valley, Chittagong (not in flo-wer),
in 1880.
