1354 (probably, according to Munro).
Malay Peninsula, extending northwards to Tenasserim, where BeJdome collccted it .on
Moolyet at 2,000 ft. in 1879.
A little known species wliich requii-es investigation and better specimens. It is
at once knowQ by the very small spikelets, and is perhaps identical with D. Brandisii.
Specimens collected at Singapore by H. AI. Ridley bear the names Buluk Butung,
hutang perith.

13. DENDEOCALAMUS LONGIFIMBRIATUS, n. sp. Gamble.
A large bamboo. Culms and culm-sheaths unknown. Leaues very large, 12 to 14
in. long, 3 to 3 in. broad, oblong-acuminate, unequal at the base and rounded into a '4
to -5 in. long, broad, wrinkled petiole, tip twisted, scabrous, acuminate; smooth above,
except the scabrous points on marginal veins; pale and smooth beneath, hairs along the
midrib somewhat long, edges sometimes scabrous; main vein broad at the base, concave,
not prominent, secondary veins 12 to 18 pairs, regular, intermediate 6 to 7, indistinct,
pellucid glands appealing as transverse veinlets when dry; leaf-sheaths shining, covered
with appressed stiff haii-s ending in a narrow callus, and furnished with long, very
prominent, falcate auricles which are thickly set with stifí curved bristles; ligide
short, very hairy, ciliate on the margin. Infioreseence a large panicle of short spicate
branchlets bearing small heads of spikelets; rachis slender, glabrous, flexuose; branchlets
sohd; heads (in bud only) -2 to -3 in. in diameter supported by blunt, ovate bracts.
Spikdets very small, glabrous, 1- to 2-flowered; empty glumes broadly ovate, Btriat<>,
flowering glume ovate, acute, keeled, often mucronate ;/»aZea oblong, ciliate on the keels;
hMes apparently none. Anthers short, connective shortly apiculate. Ovary ovoid,
glabrous surmounted by a hairy style and plumose stiijma. Caryopsis not known.
Burma, sent from the Kyauksbat and Mahvvón foresta at the extreme south of
the Mergui District, Tenasserim, in 1891.
INDIAN' BAMBUSE.^; GAMBLE.
The flowers are too young for very accurate description, but they come near to
those of D. longispathus. The beautiful long-fringed falcate auricles characterise best this
fine species which is known locally as Myenguia, wapyau (Burmese).

IMPERFECTLY KNOWN SPECIES.
14. DENDEOCALAMUS PARISHII, Munro in Trans. Linn. Boe. xxvi. 149.
Culms, culm-sheaths, and leaves unknown. Inflorescence a panicle of interi-upted globose
densely-flowered heads, the rachis pruinose-glaucous at the top. Spikelets ovate, somewhat
blunt, nearly glabrous, flattened, '3 to '4 in. long by -2 to -3 in. broad, fertile flowers
2 to 3 ; e^npty glumes 1 to 2, ovate-acute, many-nerved, ciHato on the edges and very
minutely pubescent near the apex; flowering glume similar but glabrous, those of upper
flowers mucronate, longitudinally and transversely nerved, ciliate on the edges; palea
ovate, blunt, emarginate, 2-keeled, ciliate on tbe keels and edges, 2-nerved between
them, that of uppermost flower more acute, not keeled, pubescent at the tip, reticulately
veined. Stamens not exserted; anthers with the connective produced in an obtusely
acute point. Ovary haiiy, ovoid-globose, ending in a long style and featheiy stigma.
Caryopsis large, obovate, smooth above, beaked. Brandts For. Fl. 670.
Punjab Himalaya: collected once by Lieut. Parish, but not again.
The flowers are distinct from those of the D. strietus group, and come nearest to
those of D. Suokeri, but differ in the glabrous flowering glume and bluntly acute anthers.
I t would be an excellent thing to obtain more spechnens of this, and to ascertain its true
position. The exact locality where this grows is apparently unknown. Brandia suggests
that it may be the same as the big species of the Dun and Lower Ilills; but that
species, of which I have collected excellent specimens in leaf and flower, is D. Hamiltonii.
It is more likely to have been a planted specunen of D. Rookeri, like the similarly
planted specimens found by E. E. Fernandez near Naini Tal.
