1 0 2 A^•^-ALS OF T H E B O S ' A L B O T A N I C G A E D E N , CALOTJTTA.
J a i n t c a Hills, collected by G. Mann in 1889 under the name Silloh at Sotyngia, 3,500 foet,
and said to be iised for basket-work, and to make small boxes to carry pan; from the
Assam Valley, sent by G. Mann from Sibsagar and Kamriip under the name Dullooa
(Assamese) and said to be used for buildings, mats and baskets; from Sylhet, collected
at Protabgarh by Babu Tara Kisor Gupta, and sent by G. iMann under the names
Dolu sMd^Bojail (Bengali), the former the large, the latter the saiall variety; from
Cliittagong, collected by myself at KhagovDoa in 1880, under the name Dolu, this
being ihe species which Major Lewin in hia ' Ilill Tracts of Cbittagong', Calcutta, 18C9,
speaks of as a very large kind, "much used for making mats, used in loading vessels
' w i t h cargo", and as having flowered some 15 or 16 years p r e r i c u s l y ; and finally, the
Burmese Thaikwaha collected in Katha, Gy<iwa collected in Momcik State in 1892-03
and specimens gathered at 6,000 h . on Taungmt, Ruby Mines District, in 1894,
by J . W. Oliver. Besides these, there are specimens in the Kew collection collected by
HooVer at Sitakund near Cliittagong. It is possible that when good specimens of the
flowers are collected, it will be found that there are two specicvs, the smaller Tkiikivahu,
silloh, and lajail; the larger, Pogsb, toadroo, dullooa, doh and gyutoa; but in my opinion,
and so far as it is possible to judge without tlie flowers, all the specimens before me
belong to one and the same widely distributed species.

5. TEINOSTACHYUII IIELPIÎRI, Gamble.
An evergreen, tufted, bushy or climbing bamboo. Culms 20 to 40 ft. high, -1
to 1-5 in. in diameter, greyish-green when young, sprinkled with appressed
whitish bristles, much arched so as to bend completely over and to touch the ground
where they take root; nodes somewhat thickened and whitish; internodes 20 to
50 in. long, or more, covered in the upper part with soft, whitish, velvety pubescence
when young, when old with a white band; walls thin, scarcely over -1 in.
thick. Culm-sheaths 8 to 10 in. long, persistent, thick, brittle, when young bearing
f ew appressed white bristles which leave a scar when they fall, rough towards
the base, truncate at topj imperfect Made nearly as long as the sheath, recurved,
lanceolate, acuminate, glabrous or shortly hispid, rounded at the base and decurrcnt
as a very narrow long-fringed band on the top of the sheath; ligule narrow,
conspicuously fringed with white stiff hairs, -3 to -3 in. long. Loaves very variable
iu size, -usually large, oblong-lanceolate, 6 to 1» in. long, I to 3 in, broad,
unequal at the base, and then contracted into a -3 to in. long, broad petiole;
cuspidate-acuminate above in a long scabrous twisted point; scabrous on marginal
veins, otherwise smooth; glaucescent and glabrous beneath, exccpt for a fow hairs
near the base; scabrous on the edges; main veins thick, prominent, secondary veins
T to 15 pairs, rather indistinct, intermediate 5 to 7, pellucid glands showing on dry
specnnens as transverse veinlets ; leaf-sMaths glabrous, smooth, striate, ending in a
smooth callus and a short, very deciduous, long-fringed auricle; Ugule waxvow, fringed, tiie
hairs very easily broken. Inflorescence in long terminal whip-like spikes, bearing distant
heads of few spikelets; rachis very slender, densely haiiy, thickened and bent s-fashion,

BAMBUSA J-IELFEEI Munro in Trans. Linn. Soc. xxvi. LU. PSEUDOSTACHYUM
IIELI'IÍRI, Kurz For. Fl. Burma ii. 568.
Garo and Khasia and Jaintia Hills in Assam, ai\d in liill forests down to the Pegu
Yoma and Martaban, up to 3,500 feet elevation and always in moist valleys forming
dense, almost impenetrable jungle.
The characters of the few sterile spikelets on the specimen sent by G. Mann in
1889 from the Garo Hills, have decided me to place this species in Teinostachyum rather
than in Pseudostachijum. It was first collected by Heifer in 1839 (No. 411); afterwards
by Brandis, Wathubioot (Burmese); and Kurz JVampae, wathahiool (Bnnnese). It has
also been sent from Burma by P. J . Carter and others. The Garo Hill specimens bear
tlie name Wali, and those from the Khasia Hills Tumoh. It appears to be hardly used
except for basket-work. The large unequal leaves, the long culm-internodes, (a
specimen in the Dehra Diin Forest School Museum has two joints, one 48, the other 52
in. long), the brittle thick culm-sheath witli long-fiinged ligule, and the hairy rachis to
t h e spikes seem the best characteristics. This species comes evidently very near to
T. Grißthii. It flowered in the Jaintia Hills in Assam iu 1888, and thou died off.
I t is also said to have flowered in Burma about 1S8S.

11. Cephalostachyum,
Shrubby or arborescent bamboos. Cxdms rather thin, usually smooth, straight.
Cuim-sheaths usually thin, sometimes thick, more or less auricled. Leaves various in
size, like those of Bamlusa, more usually ovate, long-acuminate. Inflorescence a terminal
globose head or a panicle of heads with spreading branchlets, heads bracteate, the fertile
flowers usually mixed with many imperfect ones or with empty glumes. Spikelets oneflowered,
elongate, the rachilla produced beyond the flower. Empty glumes 3 to 3
broad, cluifîy, many-nerved, usually long-awned. Flowering ghme similar, but more
membranaceous and with shorter awns, convolute. Palca thin, many-nerved and usually
transversely nerved, 3-keeled, keels close together, often 2-mucronate. Lodicxdes 3,
conspicuous, persistent, 3—ô-nerved, often papillose. Stamens 6, anthers long, filaments
distinct. Ovary ovoid, stalked, produced into a long tliickencd style, and divided at
t h e top into 2 to 3 short plumose stigmas. Caryopsis oblong, glabrous, beaked; pericarp
thickened, separable.
DISTEIB.—Seven species, all from the North-East Himalaya, Assam and Burma,
one only {C. pergracih) crossing the Bay of Bengal and re-appearing in Chota Nagpur.'
