7 0 ANNALS OF THE ROYAL BOTANIC GAfiDEN", CALCUTTA.
The black-fringed spikelets and naked auiiclea of tho culm-sheaths distinguish
this species. Kurz says it is called Bamboo lengka in Malay, and that it is gregarious
in the Andamans. To tliis species also I attribute the specimens sent by G. Mann
from tho Garo Hills, Assam, in 1889, under the name Washut (Garo), though the culmsheaths
and their imperfect blades are longer; also the specimen sent from Khorda,
Orissa, by Babu Sree Dhur Chakravarti under the name Bolangi bans. JIann says that
Washut is used in hut building and for basket work.

2. OxYTENAKTHEKA ALBOciLiATA, Mmro 171 Tram. Linn. Soc. xxvi. 129.
An evergreen or occasionally deciduous, densely tufted bamboo. Culms elongate,
carved, 20 to 30 ft. long, "5 to 1 in. in diameter, greyish-green, hispid above;
nodes raised in a ring formed by the base of tho sheath; internodes 6 to 15 in.
long, walls moderately tliick, '2 to '3 in. Ciilm-sheafhs 4 to 8 in. long by about
C in. broad, at first covered with dense tawny appressed hairs, afterwards smooth,
somewhat truncated, folded and coriaceous at the base; ending at the truncated mouth in a
narrow, slightly auricled, naked band; imperfect Made as long, and often somewhat longer
than, the sheath, lanceolate, acuminate, broad and rounded at the base and decurrent;
ligule very long, '5 to 1 in., truncate, toothed. Leaves linear-lanceolate, 6 to 8 in.
long, '7 to 1 in. broad; rounded at the base into a short -1 in. petiole; at the tip
produced in a setaceous point; glabrous above, except for scabrous points neai- the
margins, glaucescent beneath, scabrous on one or both margins; secondary veins
6 to 8, intermediate usually 4 to 5 ; no regular transverse vcinlets, but frequent
pellucid glands having that appearance on the lower surface; leaf-sheaihs smooth,
striate, ending in a smooth callus and truncate edge; ligule rather long, faintly
ciHate. Inflorescence a large spreading panicle of spicate branchlets; spikelets in verticDs
of about 10 to 20, supported by yellow clmfEy white ciHato bracts; rachis smooth,
slender, 1 to 3 in. long between the verticils; spHcelets slender, -6 to '8 in. long,
often curved, '1 in. broad, those bearing fertile flowers mixed with few sterile ones;
empty glumes I to 2, ovate-acute, wliite-ciliate; then one male flower, followed
by 1 or 2 hermaphi'odite flowers; flowering glumss elliptic, acute or faintly emarginate,
many-nei-ved, wliite-'ciliate on the edges, convolute; palea shorter, often much shorter,
ovate obtuse, 2-keeled, cihate pn the keels, that of last flower not keeled, convolute,
ciliate only at the tip. Stamens long, exserted; filaments at first connected in a shoi-t
tliick tube, afterwards in a long, very membranous one; anthers long, greenish-yollow,
long hirsute, apiculate. Ovary narrowly ovoid, much acuminate, pubescent, ending in a
long sUjle divided above into 2 white stigmas. Caryopsis elongate, oblong, cylindrical,
acuminate. GIGANTOCHLOA ALBOCILTATA, Kurz For. Fl Burma ii. 555.
INDIAN BAMBFSE^i GAMBf-E, 71
Throughout Burma, cliiefly in mixed forests. Collected by Falconer in Moulmein,
Brandis in Houndraw valley and Toungnyo in 1880; Dr. Mason in Toungoo Hills
in 1857; Kurz in Thaungyin and Pegu Yomas in 1871; J. W. OHver at Pyinmana
in 1891; P. J. Carter in Pegu; W. T. McHarg in Tenasserim in 1892.
This is the well-known Wapyugale (little white bamboo), also Wagok of Tenasseiim,
and it is easily recognized by its narrow, white-ciliate, curved spikelets, by the
absence of a terminal imperfect flower, and by the long hgules of the culm sheath.
From the dates given by collectors it appears to have flowered in 1857, 1871, 1880,
1891-92. It is a species of very little value, and is even troublesome in the teak
plantations.

3. OXYTEN^ANTHERA SINUATA, n. sp. Gamble.
Culms and culm-sheaths not known. Leaves 10 to 12 in. long, 1-2 to 1-5 hi.
broad, oblong-lanceolate, acuminate; rounded ahnost cordatoly at the base into a -5 in.
long, broad, tliick, hairy petiole ; ending above in a scabrous, twisted, setaceous point;
somewhat scabrous above, softly pubescent beneath, scabrous on the edges ; main vein
hardly prominent, secondary veins 10 to 12 paii-s, intennediate 7 to 8 ; leaf-sheaths
glabrous or slightly pubescent, faintly striate, keeled, ending in a nan-ow ciliate callus
and bearing a few long deciduous bristles ; ligule rather short, thickly pubescent. Infloreseance
a panicle with spicate branches bearing round heads of sterile and fertile spikelets
; rachis sinuate, softly pubescent, joints -5 to I'o in. long ; heads up to -5 in. in
diameter; spikelets narrow, conical, '3 to '4 in. long, acuminate, minutely hairy, bearing-
2 to 3 empty glumes and then 2 to 3 fertile flowers; empty glumes ovate, mucronate
ciliate on the edges, many-nerved ; flowering glumes similar but longer, and longer
inucronate, the uppermost convolute ; palea of lower flowers blunt or bifid, 2-keeIed
ciliate on the keels, 2- to 3-veined between, that of upper flowers long-acuminate,
glabrous, not keeled. Stamens exserted, tube at first thick, enclosing the ovary, afterwards
elongate, membranous; anthers narrow, connective produced into a hairy acumen. Ovary
broadly ovate, hairy, surmounted by a long haii-y style and plumose stigma. Caryopsis
not known.
Malaya : collected at Serumban in Sunjei Ujong in 1885 (Herb. Singapore).
A very little known kind, said to be used for making baskets and to be called
Poio, luU miniak. I also consider Ridley's specimens from Gunong Panti and Hulu
Kahary, Johore, to belong to this, though they have only one fertile flower and a glabrous
spikelet.
