GuirriTun, Kurz For. Ft. Burma ii. 566.
Bhutan {?), Assam, Chittagong and Burma. Collected by Griffith in the forests
of Wullaboom in hilly country, also in the Khasia Hills. Found in Assam, in Sibsagur
and Dibrugarh, by G. Mann, in 1889 (flowers) and 1890.
The long narrow spikelets in axillary fascicles, spikes or short panicles, ore very
characteristic.° The specimens sent by G. Mann bear the Assamese name of Bebtl, Mi,
ami the plants wore said to have grown in low damp places in tlie plains. To this

species I also doubtfLilly refer the specimens which I collected in 1880 at 4,000 feet in
the British Bhutan hills and called Rivelt by the Lepchas. Mann says tl.at the culms
are used for basket work and to make pipes.

A tall, semi-scandent bamboo. Culms at first erect, afterwards supported by the
branches of the forest trees under which they grow, and then branches pendulous, 10
to 20 feet long, 1 to 1'5 in. iu diameter, bright green; nodes marked b y a narrow but
conspicuous ring; iatt-rnodes 14 to 18 in. long, rough above and having a white glaucous
band below the node; walls thin, -05 to -15 in. Cidm-sluaths thin, papery, H) to 12 in.
long by 3 to 4 in. broad, the sides parallel below, gradually narrowing above to a
truncate top, which is not auricled; 1 to 1-2 in. broad, tliickly clothed on the back with
brown-black appressed hairs ; imperfect blade s\ibulate-acuminate, reflexed, slightly
decm-rent on the sheath, 5 to 7 iu. long by '4 to '5 iu. broad, striate, somewhat hairy;
ligule -1 in., entire. Leaves oblong-lanceolate, acuminate, 6 to lô in. long, 1 to 2 iiu
broad, unequal at the base; rounded or attenuated into a -3 to '4 in. long petiole; ending
above in a subulate, scabrous twisted point; glabrous above, sparingly l i a n y and whitisli
beneath, scabrous on one margin; main vein broad, yellowish, conspicuous, secondary
veins 8 to 10 pairs, intermediate 6 to 7, transverse veinlets scanty, not prominent, foi'nied
by glands in the leaf; leaf-shcaths glabrous, striated, truncate at t o p ; liyiik narrow, f a m t ly
toothed. Inflorescence a large terminal drooping panicle of spiciform branchlets, the spikes
supported by ovate-acuminate bracts at the joints of the rachis and bearing cliiefly fertile
spikelets; rachis smooth, slender, thickened above. Spikelets '5 to 1 in. long, bearing 2
to 3 fertile flowers and 1 terminal incomplete flower; rachilla slender, smooth, concavely
flattened below, thickened above and slightly ciliate at top; empty ylime ovate, nmcronato,
•2 in. long, faintly hksute on the back, 5- to 7- nerved; floiacring-glumas 1 or 2, similar
but longer, mucronate and transversely veined; palea rather sliorter t h a n flowering glumes,
2-kceled, blunt or emarginate, ciliate on the keels, 1-nerved between keels and 2- to
3-ncrved at the sides. Loâicules small, "1 in. long, ovate, triangular, ciliate above, concave
below, 3- to 5-uerved, persistent. Stamens exserted, filaments slender, anthers obtuse:.
Ovary depressed-globose, smooth, stipitate, the style included in the long beak of th(i
pcrigynium and ending in 2 short plumose stigmas. Curyopsis glabrous, ovoid, on a
thick stalk and surmounted by a beak.
Slopes of the Western Ghats from N. Kanara duwn to Cape Comorin, usually at
from 3,000 to 5,000 feet, and almost always in the undergrowth of big tree-forest;
Anamalai Hills at 4,000 feet.
This pretty bamboo is distinguished easily from the other species by its long, lax.
drooping, many-flowered panicle, broad leaves, papery hirsute sheath, and small blunt
lodicules. It was gathered in flower by Beddome in the Anamalai Hills (year not
recorded); by myself on the Sispara Ghât in ISS^i and 1B84, and by J . A. Bourdillou
