pale terminal head aboiit 1 in. in diameter, supported by a leaf and broad, rounded,
glabrous, sheath-like bracts, and consisting of many long aristate empty glumes or
sterile spikelets, -with few esserted fertile spikelets.- Spikelefs '7 to '8 in. long; empty
ghmics sessile, or -with few empty bractlets at the base, '5 to -6 in. long, ovate,
concave and ending in a long, usually -2 in., scabrous awn, many-nerved, sometimes
pubescent on the back below the awn; floiomug glwne similar but with a shorter awn;
palea as loiag as the flowering glume, thinner in texture, toany-nerved, with both
longitudinal and transverse veins, 2-keeled, the keels close together, bifid-mucronate at
apex, hairy below the keels and at the tip, racliiUa produced, short. Lodictiles about -15
long, lanceolate or spathulate-laiiceolate, 3—o-noi-ved, minutely papillose, pubescent, ciliate
at the tip. Stamens exserted, filaments long ; anthers long-apiculate. Ovary ovoidlanceolate,
extended into a long conical style with S hairy short stigmas. Carxjopsis
chestnut brown, glabrous, ovoid-globose, conical above and wrinkled, ending in a beak
formed by the persistent base of the style and supported by the persistent glumes
and lodieulcs. Kurs For. Fl. jSiirma ii. 563.
Khasia Hills, Mishmi HiUs, Patkaye Range and Manipur, ascending to 5,000 ft.
Collected by Griffith (Nos. 6733, C718), C. B. Clarke and G. Mann.
This graceful species is distinguished with some difficulty from C. capitalum; but it
has much smaller leaves, longer ligules, a bifid palea and apiculate anthers. The culms
and culm-sheaths have unfortunately not been described. It was gathered in flower by
Griffith in 1835, by C. B. Clarke in 1872 and 1885-86, and by G. Mann in 187«.
Mu!\ro says that this is called Betee bans; but the bamboo more commonly known as
Be/ee or Behti is Tcimstachjum Griffithii, Munro. Griffith's specimens were found on the
summit of the Patkaye Range, and on its southern side, on his journey from Naga to
Hookoom (Griff. Journ. 64).

A sln-ubby, semi-scandent bamboo. Ciilm^ thin, dark green, rough, whitish below
the nodes, which are marked by a conspicuous ring. Culm-sheaths tliin, papery, strawcoloured,
6 to 9 in. long, 2 to 3 in. broad, sides parallel, top rounded and ending in
a concave sinus -7 in. in diameter, with rather sharp, triangular, glabrous auricles;
imperfect Made 4 to 5 in. long, -3 to -5 in. broad, subulate, acuminate; broad. Leaves
very large, ovate or ovatedanceolate, unequal at the base; wedge-shaped or rounded
into a thick -3 to -4 in. wrinkled petiole; ending above in a scabrous, setaceous tip;
10 to 16 in. long, 1 to 4 in. broad; main, vein prominent, pale, secondary veins 8 to
18 pairs, conspicuous, intermediate 7 to 10, no regular transverse veinlets, but distant
pellucid dots which give sometimes the appearance of transverse veinlets on the
underside ; leaf-sheaths striate, ciliate on the edges, ending in a broad, thick,
emarginate callus, and produced beyond it to meet the broad ligule, wliich is again
long produced and often up to -2 in. or more. Infloreseence a thick, terminal
globular head, often 2 in. in diameter, composed of clusters of spikelets, some

fertile, some sterile, supported by broad, striate, keeled, aristate bracteolcs. Spikelets
1-flowered, acuminate, long-aristate, "6 to '9 in. long; empty glumes -6 in. long, ovatelanceolate,
long awned, glabrous except the scabrous awn, striate, somewhat keeled;
flowering glume similar but lanceolate-acuminate, and with a shorter awn and transverse
veinlets ; palea membranous, both longitudinally aiid transversely veined, onding in a blunt
hairy point, convolute; rachilla produced, short. Lodiades ovate-lanceolate or spathulato,
ciliate, 3-nerved, '2 in. long, minutely papillose-pubescent. Stamens exserted, filaments long,
anthei-s bluntly mucronate. Ovary ovoid, surmounted by a long style which is flattened
above and finally divided into two short plumose sliymas. Caryopsis chestnut brown,
shining, broadly ovoid, stalked, '3 in. long, '15 in. broad, cui-vcd above, ending in a
beak formed by the persistent base of the stylo, and supported by the persistent
glumes and lodicules; pericarp crustaceous.
North-East Himalaya in British Bhutan, up to 5,000 feet; also in Manipur at 7,000
feet. Collected by Griffith (1835); by myself (1879) at Dumsong in British Bhutan; and
by G. Watt in Manipur in 1882.
This species is at once distinguished from C. capilaium by the large broad leaves
and long ligules; and from C. Fuchsiamm by the absence of" ciliated fringes to the
leaf-sheatLs and by the undivided palece. The specimens of leaves and culm-sheaths
sent from Upper Burma by J. W. Oliver under ,the name of Gyawa (Burmese),
Lalca (Kachin), resemble this, but the ligules are much smaller and the culm-sheaths
are ciliate at the top.

4. CErHALOSTACEvuM FucHSJANUii, n. sp. Gamhlc.
A medium-sized, arborescent, send-scandent bamboo. Culms small, soft, tliin-walled,
pale, verticillately branched from the nodes. Culm-sheaths tliin, striate atjd reticulately
veined at the edges, sides nearly parallel, rounded at the top on each side into a deep
(often 1 in. deep and -5 in. broad at bottom) concave long bristly-fringed sinus, 12 in.
long by 4 in. broad, clothed on the back with appressed light brown pubescence;
imperfect blade inserted at the base of the sinus, reflexed, subulate, 6 to 8 in. long, -7 to
•8 in. broad, closely pubescent below; liguk small; younger sheaths cylindrical, the
mouth furnished with rows of long, white, stiff, bent bristles. Leaves large, ovate-lanceolate
angled or rounded at the base rather abruptly into a -5 to -6 in. long, thick petiole;
cuspidately acuminate with a scabrous, twisted point; glabrous on both sides, scabrous on
the edges; 8 to 14 in. long, 2 to 4 in. broad; main vein prominent, shining, secondary
veins 7 to 10 pairs, intei-mediate 8 to 10, pellucid glands giving the appearance of
transverse veinlets when diy; leaf sheath soft, dark green, striate, thickly long-ciliate on the
edges, ending in a rounded callus and produced at the top into an elongated amide
thickly clothod with thick, white, stiff bristles which are often -6 to -7 in. long; Ugule
moderately long, ciliate. Inflorescence a dense, globular, tei-minal bead, 2'5 in. in diameter,
or else an elongated, densely packed, terminal, congested spike of superposed Leads'
