keeled, ending in falcate auricles with few (usually 5-6) stiff bristles; Ugule short, truncate,

Hills of Jaunsar in North-West Himalaya, near llundali, at 7,000 to 8,000 ft., 1892-.
This handsome species is at once distinguished by its single culms arising from a
long creeping jointed rhizome, often 3 feet loug between the stolons; by its auricled
sheath, green culms and loaves thinner than those of its nearest neighbour A. SfaUuJlora.
It is used for baskot-work, and is apparently confined to the one locality.

2 3 , ARUNDINARLL ROLLOANA, ii. sp, Gct^jihle.
A shmbby bamboo with stoloniferous distant culms, the rhizomes at first covered
with shining, acute, imbricating scales, afterwards jointed, the joints about -0 in. lono-.
Culms about 8 ft. high, -i in. in diameter, slightly rough, green at first, afterwards
yellow, somewhat flattened on one side; nodes somewhat swollen, lower ones rootin«^;
internodes 8 to 12 in. long, walls rather thin, less than -1 in, Qulm-slmtlu 4 to 6 in. lon°'
1 to 2 in. broad, at first covered with scattered appressed bristles, afterwards glabrous,'
shining, eiliate on the edges, narrowed oonvexly in the upper third into a rather broad
truncate mouth, which is furnished with long, recurved, rounded, falcate auricles with
lottg bristles; imperfect hlade 1-5 to 2 in. long, narrow, subulate, recurved; ligule narrow.
Leaves C to 8 in. long by I to I'o in. broad, oblong-lanceolate ; rounded at the
base into a short, very broad, flat petiole; ending above in a rather short acute poii.t;
smooth above, sparsely hairy beneath ; the edges cartilaginous, spinulose-scabrous ; main
reins hardly seen above, shining beneath, secondary veins 8 to 10 pairs, intermediate
about 7, transverse veinlets vfti'y protninsnt beneathj iiuinQrouSj straight and regulfii' •
haf-shcaths striate, sparsely stiigose, hairy, ending in a narrow line and a rounded, longciliate
auricle ; ligule long, membranous, deeply cleft. Inflorescence, etc., not known.
Naga Hills : found by James Hollo in the Zallah Valley at 5,000 to 7,000 ft.
in 1889, and by Sri Gopal Baneijoe the samo year, and sent by G. Mann.
This is a remarkable species on account o£ the breadth of its leaves. In its
rhizome and distant culms and in the character of the culin-sheaths it resembles
A. jaunsarensis. It is known by the Naga name of Jlpvo.

24. AIIUKDINAKIA AUBBUKCTA, Mmro ia Trans. JAnn. 8oc. xxvi. 32.
A graceful, wiry, erect shrub, growing in thick clumps. Culms 10 to 15 ft. high,
•3 in. in diameter, olivo green, smooth; nodes slightly swollen; mtornodes 6 to 10 m.
long, cavity very small; branchlets in whorls from tho nodes. Culm-sheaths 2 to 6 in.
loner' -0 in. broad at baso, thin, papery, striate, glabrous, gradually attenuate upwards to
a naked or fimbriate mouth ; imperfeet blade subulate, leafy, "5 to 1-5 in. long, recurved ;
ligule long, fimbriate at tip. Leaves narrow, linear, 2 to 4 in. long, -2 to -3 ui.
broad; narrowed at tho base into an extremely short petiole ; tip setaceous, edges
rcvolute ; smooth above except the scabrous marginal veins, palo beneath ; edges
scabrous serrate; main vein narrow, not conspicuous, secondary veins 3 to 4 pairs,
intermediate 4 to 5, transverse veinlets none or very scarco, pellucid glands many;
leaf-sheaths striate, loose, glabrous or slightly hairy when young, ending in a callus
and somewhat produced, with a few very deciduous bristles; ligtdo rather long, pubescent.
Jnfloresence, ete., not known.
North-East Himalaya and Khasia Hills: collected in 1850 at the Moosinai falls,
Khasia Hills, 4,000 ft., by Hooker (No, 558) ; and at Kalapaui, 4,o00 ft., by Griffith
^No. 1407). I also identify as this C. B. Clarke's No. 19120 from Shillong (which
I have figured in default of a specimen o£ the type) ; G. Mann's specimen No. b fi-oni
the Khasia Hills, 5,000 ft., 1885, named, U-lcadai-namlang, and from the Mahtedu river,
Jaintia Hills, 4,500, named Lomhnang, namlang, gathered in 1889 ; and those sent by
Mr. W. A. Kennedy in 1891 to the Calcutta Botanic Garden from Sikkim, though this
latter has a more hairy leaf-sheath, and more eiliate leaf auricles.
Used in building native huts. It would probably make excellent fishing rods.

1, 5, 6 from C. B. Clarke's specimens ; Nos. 2, 3, 4 from G. Mann's.)
2 5 . AUDNDINARIA KUEZII, n. Gamble.
Apparently a bushy shrub. Culms '3 to '4 in. in diameter, smooth ; nodes marked
with a thick ring and bearing very numerous, long, wiry, filiform, geniculate branchlets.
Leaves very thin, linear-lanceolate, 2 to 4 in. long, -2 to -3 in. broad, tapering
unequally at base into a very short petiole ; acute above with a short point; smooth
on both surfaces except for a few long white bulbous-based hairs on the veins
beneath; edges smooth ; main vein thin pale, secondary veins 2 pairs, intermediate
5 to 6, transverse veinlets very few and inconspicuous ; leuf-sheaihs slender, striate,
ending in a small callus and slightly produced at the edges, and furnished with a few
thin ciliffi ; ligule short, sometimes eiliate. Inflorescence, &c., not known.
Coasts of Southern Burma : collected by Kurz on his last tour in 1878.
It is not quite certain in wliat exact locality this was gathered, but the plant
is quite unlike any other species of the eastern region, though it comes near to
A. falcate, o£ the "Western Himalayas. It is remarkable for its very thin leaves and
geniculate pale branchlets.
