26 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
26. ARUNDINARIA MANNII, 2. sp. Gamble. 
A slender, graceful, tufted, climbing, wiry bamboo. Culms solid, having no cavity, :5 
in. thick, 30 ft, high, much branched; nodes thickened, bearing many geniculate branchlets ; 
internodes 3 ft. long, smooth.  Culm-sheaths 12 to 18 in. long, convolute, apparently 
persistent, very thin and slender, 72 to 3 in. broad at the top, rough with sparse, 
stiff, brown, appressed bristles; imperfect blade inserted on the sheath with the same diameter 
and eontinuous with it, very long, linear, often 9 to 10 in. in length, point long, setaceous, 
closely appressed hairy within at the base; Пуше narrow, dentate. Leaves 6 to 9 in. 
long, 77 to nearly 1 in. broad, thin, papery, lanceolate; rounded or attenuate at the base 
into a short, “1 to "2 in. long, wrinkled petiole ; the point at first thickened and scabrous 
hirsute, then surmounted by a long, setaceous, hair-like apex; smooth above except the 
scabrous points on marginal veins, somewhat glaucous and sparsely rough hairy beneath; 
scabrous on one edge; midrib vein narrow, shining, secondary veins about 5 pairs, 
intermediate 5 to 6 hardly recognizable from the secondary, no transverse veinlets; 
leaf-sheaths glabrous, striate, ending on one side in a round shining callus without 
auricle, оп the other in a short pointed auricle with a few long stiff bristles; ligule 
small, hairy, ciliate. Inflorescence, &c., unknown. 
Jaintia Hills in Assam at about 3,000 ft, 
A very curious species, which has been placed in this genus on account of its 
resemblance generally to A. Prainii, especially in the solid culms. The very long | 
narrow sheaths are remarkable, and іп its leaves it resembles Cephalostachyum. It was 
found at Amkasur, about five miles from Jarain, in April 1889, by С. Mann, and it is 
called Beneng (Khasia) Mann states that it is much used, split, as a binding material 
in building huts. 
Prate No. 26.—Arundinaria Мапий, Gamble. No. 1, leaf-branch; 2, culm-sheath— 
of natural size; 3, leaf-sheath, both sides—enlarged. 
2. Phyllostachys, Sie. and Zucc. 
Shrubby ceespitose bamboos. Culms smooth, flattened оп one side; nodes prominent; 
internodes rather short; branches fasciculate at the nodes. Culm-sheaths papery, striate, 
rounded above ; imperfect blade narrow, subulate. Leaves petiolate, articulate on the sheath, 
small or moderate-sized, transverse veinlets very numerous, tessellate; Jeaf-sheaths loose, 
smooth. Inflorescence consisting of spicate branchlets arranged in a leafy terminal panicle ; 
the spikelets supported by prominent imbricating bracts which are sheath-like and bear 
sometimes a leafy imperfect blade. Spikelets 2 to 3, alternate, with 1 to 4 fertile flowers 
and a terminal imperfect one; rachilla articulate between the flowers and produced beyond 
into a terminal imperfect flower; empty glumes 2 to 3, many-nerved, usually unequal, 
glabrous, often ending in a leafy imperfect blade; flowering glume ovate-lanceolate, many- 
nerved, acuminate ; palea scarcely shorter than flowering glume, narrow, 2-keeled, many- 
nerved, often bimucronate. JLodicules 3, usually unequal, lanceolate, acute, veined. Stamens 
3, long-exserted, filaments filiform; anthers linear. Ovary stalked, rounded, glabrous; style 
long, rdg above into 3 long feathery stigmas. ^ Caryopsis not known. 
Distrib.—Eastern Asia, in China and Japan, extending westwards to the Himalaya 
MS ы “ Assam, and containing five or more species. Тһе most important of these,
