22 ANNALS OF THE llOYAL BOTANIC GARDEN, CALCUTTA.
This graceful Httle climbiug bamboo has 6 stamens, and, under the impression
that the character given by Bentham and Hooker to tho section Triglossece was
permanent, I described it as a new genus, Microcalajmis, in 1890. It aj^poars, however,
from a note by Professor D. Oliver to plate 1969 of Hooker's ' Icones Plantarum,'
that not only was the name Microcalamus already pre-occupied, but that the authorities
at Kew saw nothing to prevent bamboos haraig the other characters of Arunclinaria
being descriljcd under that genus in spite of a lai-ger number of stamens, so that I
do not hesitate now to transfer my plant to Arundinaria. I cannot, hoAvever, agree
with Professor Oliver in referring A. Prainii to A. /curilensis, Ruprecht; for I can trace
no points of agreement cxcept those of the 6 stamens and spOielets with about the
same number of distichous flowers. G-. Mann gives the Naga name as Scmpit, and
says that the plant is used for basket-work and for building huts. Mr. Rollo gives
the Naga name Kevva.

SPECIES OF WHICH THE FLOWERS ARE NOT KNOWN.
19. Arundinaria jiiceophylla, Mimro in Trans. Linn. Soe. xxvi. 32.
A gregarious, low, c»spitose slu'ub. Cuhns 2 to 4 ft. iugh; internodes 2 to 3 in.
long, very glabrous; branches many from the nodes, semi-verticil late. Culm-sheaths
not known. Leaves small, narrow, linear-lanceolate or almost lanceolate, acute, 'l to '2
in. broad, under 1 in. long, shortly mucronate, the margin almost membranaceous,
fimbriate or glabrous; leaf-sheath often dark-coloured, striate, haiiy above, long fimbriate
at the top; secondaiy veins 2 paii-s, hardly consixcuous, transverse veinlets many,
not raised; ligule scarcely visible. Eamuusa microphylla, Griffith Journ. i. 242, 259, &c.
Bhutan: collected by Griffith at Sanah, 7,000 ft., and at other places between
6,000 and 10,000 ft.
It is possible that C. B. Clarke's No. 38980, collected at Soyung, 5,600 ft.,
Khasia Hills, in 1885, described as dwarf, and said to be used for pony fodder, may
be this species, but the leaves are lai-ger. Griffith describes A. mierophylla as a dwarf
plant, ' forming large patches in wet places' and clothing tho sward on the Dhonglaila
Pass at 10,000 ft.
No plate available—description after Munro.
20. Arundinahia hirsuta, Munro in Trans. Linn. Soc. xxvi, 30.
A small shrubby bamboo with single stems from the rhizome. Culms greyishgreen,
4 to 8 ft. high, -2 to '3 in. in diameter, nodes glabrous, raised; internodes up to
13 in. long, often sb-igosely hirsute above, walls rather thin. Culm-sheaths thin, papery,
about G in. long and 1 in. broad at base, striate, covered with long brown liair.s,
rounded at top and ending in large, recurved, long-ciJiate auricles; impetfcct hlade subulate,
acuminate, recurved; H(jule narrow, pubescent. Leaves oblong-lanceolate, 3 to 5 in. long
INDIAN BAMBDSEiEs GAMBLE. ¿o
by -5 to -7 in. broad; rounded at base into a short, '1 in. long, broad petiole; tip
a subulate, twisted, scabrous point; smooth above, pale and strigosely white hairy
beneath; edges cartilaginous and scabrous serrate ; main vein narrow, shining,
secondary veins 4 to 6 pairs, intermediate 7, transverse veinlets very numerous,
straight, regular and strong; leaf-sheaths striate, covered with long stiff bristles ending
in a° hairy callus and rounded, reflexed auricle bearing long, stiff, almost spinescent
haii-y bristles; Ugiile elongate, hairy, often of dark colour. Inflorescence, etc., unknown.
Khasia and Naga Hills at 5,000 and up to 9,500 ft. : collected by Griffith on
rocks at Mynmg, 5,600 ft. ; by Hooker in 1850 in woods at Syong, 5,700 ft., and
Moflong, 6,000 f t . ; by G. Mann at Myrang in 1890 under the Khasi name U-sloh, and
by C. B. Clarke at Shillong (No. 44651) and at Jakpho, Naga Hills, 9,500 ft.,
(No. 51313) in 1885-86.
This pretty bamboo much resembles A. Wightiana, and might almost be placed
under it except for the very marked atu-icles and bristles of the culm- and leaf-sheaths.
Mann says it is used for the walling of huts to hold the mud plaster. Jlunro refers
to Hooker's having described it as possessing spinous stems, but says he has found
no trace of spines unless the very stiff leaf-ciliie were referred to.
