or more chaffy bracts, one or more racemes of spikelets-1 in. l o n g ; bracts ovate-lanceolate,
up to 1 in. long, truncate at tip or with a very small imperfect b l a d e ; rachis of raceme
sinuously curved, flattened. Spikelets 5 t o 7 in the raceme; 1-flowered w i t h a terminal
f r e e rachilla bearing a v e r y minute imperfect flower; rachilla with a r i n g of liairs below
t h e flowering glume; empty glumes 2, membranous, oblong, acute or muci'onate. 3- to
5-nerved, the midrib prominent, more than half the length of the spikelet; flowering
glumes ovate-lanceolate, 5—7-nerved, shortly mucronate, ciliate at the t i p ; palea as long
or longer, 2-keeled, keels glabrous except at the very tip, shortly bi-mucronate, 1-nerved
on either side of keel. Lodicules 3, oblong, or obovate, acuie, 3—5-veined, ciliate
on the edges, one rather shorter and smaller. Stamens exsei-ted, anthers obtuse or very
s h o r t l y apiculate, purple. Ovary ovate, glabrous, elongated into a thick style, which
is finally divided into 3 long plumose stigmas. Caryopsia linear-oblong, furrowed on
one side, shortly acute. Thamnocalamus Falconeri, JIoolc. fil. MS., Munro in Trans.

Himalayan range from Kumaon to Bhutan; collected by Wallich in Nepal in 1821;
by Strachey and Winterbottom at the Madhari Pass, Kumaon, 8,000 f t . ; by Dr. Jamieson
(Saharanpur Garden collection); by 0. B. Clarke in Sik]<im at Laghep, 9,000 ft., in
1876 (No. 27760); by T. Anderson at Senclml, Darjeeling, 7,000 ft., in 1868 ; by
G. A. Gammie at Tendong, 7,000 f t . , and by myself near Darjeeling.
This species is veiy little known: it is clearly a Nepaleae kind chicfly, and
only just extends eastwards into Bhutan and westwards into Kumaon. The dates of
flowering are given by Wallich's collection of 1821 and C. B. Clarke's of 1876,
INDIAN BAMBUSEJE; GAMBLE. ^^
T. Anderson's specimeus bear the name Pummoon (Lepclia and G. A. Gammie's that
of Pao mu7ig, which presumably is the same. The small sheaths enclosing short sinuous
racemes of 1-flowercd spikelets, with the absence of regular transverse veins to the
leaves, at once characterize this species. Judging from the figuro and description, this
is the A. falcata, Nees, of Riviòre's ' Les Bambous,' page 308. It is regularly
cultivated in Europe, and, according to a lettor by Dr. M. T. Masters ÌQ Nature of
J a n u a r y 20, 1881, flowered gregariously a few years previously.

18. Arundinaria Prainii, GamUe.
A small wiry climbing shrub. Culms thin, slender, smooth, yellowish, curving, up
to 30 f t . long, '2 to '3 in. in diameter; nodes swollen in a well-marked ring; internodes
short, usually 8 to 9 in. long, longer in the middle, decreasing upwards, walls thick,
often quite solid, branchlets fasciculate from the nodes, the loaves becoming smaller
upwards and finally very much reduced, aciculate. Culm-sheaths thin, somewhat scabrous
above, 2 to 6 in. long, '4 to '8 in. broad, attenuate convexly in the upper half to
a very narrow point; imperfect Made short, "1 to '2 in., needle-like; ligtde short, rounded.
Leaves small, thin, oblong-lanceolate, 2 to 4 in. long, -3 to '7 in. broad; rounded at
t h e base into a short -1 in. long petiole; ending above in long curved setaceous
points glabrous on both sides; one edge scabrous ; main vein scarcely pi'ominent, secondary
veins 2 to 3 pairs, intermediate 4 to 7, transvei'se veinlets none; leaf-sheath striate,
smooth, ending in a prominent glabrous callus below the petiole and produced upwards
at the sides; ligule long, rounded, blunt. Inflorescence in terminal or axillary panicles
bearing distant spikelets in the axils of sheath-iike straw-coloured bracts; rachis veiy
slender, wiry, smooth, geniculate. Spikelets 1 to 1'4 in. long, on slender pedicels, bearing
2 to 3 empty glumes, 3 to 6 fertile flowers and a termioal imperfect flower, distichously
arranged on alternate sides of a wiry flexuouse rachis; rachillie clavate, flattened;
empty glumes usually 2, the lower 1-keeled, ciliate on the edges, lanceolate, the upper
ovate, acute, 3—5-nerved, ciliate on the tip; floioering glumes triangular, falcate, acute,
glabrous, 9- to 11-nerved, nerves prominent; palea falcate, as long as flowering glume,
2-keelcd, minutely ciliate on the keels, and at the acute or bifid apex, Lodicules 3, two
broadly ovate, 3-nerved, f a i n t l y ciliate, the t h i r d lanceolate acute, 1—3-nervod. Stamens 6,

Naga and J a i n t i a Hills in Assam, found b y Dr. D. Prain in flower at Pulinabadza,
7,870 ft., Naga Hüls, in 18>6, on the edge of a precipice; and by G. Mann on the
J a r a i n road, about 5-| miles from Jowai, Jaintia Hills, 3,500 ft., in 1889. I also
i d e n t i f y with this the specimens collectod by Mr. James Hollo in the Zulla Valley,
Naga Hills, 5,4.00 ft., in 1891.
