2. PHYLLOSTACHYS MANNII, n. sp. Gamlle.
^ A CEcspitosG sln-ub. Culms 15 to 20 ft. high, 1 to 1-3 in. in diameter; internodes
8 in. long, yellow, flattened on one side. Culm-sheaths papery, straw-coloured, 8 to
9 in. long, 1 to 2 in. broad, rounded at the top and truncate; imperfect Made 2 to 3 in.
long, recurved, narrow, subulate, decurrent on the sheath; ligtUe broad, long-pectinate.
Leaves thick, 4 to 5 in. long, -o to '8 in. broad ; rounded at base into a rather long
•3 in. petiole ; shortly acuminate at tip ; smooth and glabrous on both surfaces except a
few wliite hairs near tho midrib below; spinulose-serrate on one edge; main vein
prominent below, shining, secondary veins o pairs, intermediate 7 to 8, transverse
veinlets extremely numerous and very finely tessellate; leaf-shoaths loose, glabrous,
smooth, straw-coloured, ending in a narrow ciliate callus with a few deciduous bristles;
li[/ule short. Inflorescence, etc., unknown.
Cultivated at Shillong, Khasia Hills, 5,000 ft., and said to have come from the Naga
Hills: collected by G-. Mann in 1889, and called Deo.
This is a pretty species which I cannot identify with any other I have seen, and
which I consequently describe as new, but with some diffidence. I have received specimens
fi-om J. W. Oliver, collected from plants cultivated at Bernardmyo and called by
the Shans ^ 3Iai-pang-pUk^ which I think belong also to tins specics. The culms are
used for walking sticks.

Arborescent, or shrubby, or rarely chnibing bamboos, sometimes thorny, sometimes of
largo size; a few species gregarious. Ctdma from a thick rliizome, usually casspitoso, occasionally
stoloniferous from long underground shoots. Culm-slicaths various, the sheath
usually broad and the imperfcct blade broad, triangular in shape. Leaves small to moderatesized,
rarely large, linear or oblong-lanceolate, acuminate, shortly petiolato; leafsheuths
variously auricled. Ivfloreseence more usually a large leafless compound panicle bearing
spikelets in heads in spicate branchlets; sometimes in leafy panicles or paniculate spikes,
and occasionally short. Spikelets with 1 or many fertile flowers usually supported by

1 to 3 empty glumes ; flowering glume ovate-lanceolate, usually mucronate ; paha two-keeled,
the keels ciliate or not, the point usually entire. Lodiculos 3, membranous, generally
obtuse, ciliate. Stamens 6, filaments free, often exserted; anthers narrow, tip obtuse or
apiculate or penicillate. Ovary oblong or obovato, hairy at the apex; style short or
elongated; stigmas 1 to 3, plumose or hairy. Caryopsis oblong or Hnear-oblong, acute or
obtuse, furrowed on one side; pericarp thin, adherent; embryo conspicuous.
DrsTKiii.—Besides the.24 Indian and Straits species herein described, there are about
fi Chinese {B. tuldoidcs, Munro; B. angulata, Jlunro; B. Ireviflora, Munro; B. Jlexuosa,
Munro; B. Bcecheyana, Munro, and B. Oldhami, Slunro) and 1 JIalay. species {B. cornuta,
JIunro) which are well known; and there are also about 7 spccies from Eastern Asia and
12 from the Malay Islands which are only very imperfectly known and described. Of the
24 liere described, 8 belong to the Western Peninsula, 9 to the Burmese region, and 5 to
Malaya and the Islands of the Bay of Bengal, while 2 (JS. vulgaris and B. nana) are
cultivated species frequently met with throughout tho Indo-Malayan. area, and one of
them [B. vulgaris) also in America. Only one is certainly known from Australia, viz.:
B. aruhmica, von Muell. from tho North-East.
