46 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
narrow leaves, long petioles, and a narrow papery culm-sheath much resembling that 
of Dendrocalamus strictus, which this does to some extent, may probably prove to 
be this species; but there is not enough evidence as yet.

8. OxYTENANTHERA Воопвоплом, n. sp. Gamble, 
А moderate-sized bamboo forming open clumps with rather a straggling habit. Culms 
with long internodes. Culm-sheaths coriaceous in texture, 6 to 12 in. long, often 6 in. 
broad, glabrous -except for a few stiff black hairs below, striate, only slightly narrowed 
at the truncate top; imperfect blade 2 to З in. long, triangular, very sharply mucronate, 
striate, glabrous except for a few stiff black hairs within, decurrent at the base into 
rounded, reeurved, entire wings which line the whole of the upper edge of the sheath; 
ligule 2 in. long, glabrous, faintly serrate. Leaves linear-lanceolate, acuminate, thin, 6 to 
9 in. long by 1 to 19 in. broad; unequally attenuate at the base into а 79 in. long 
petiole ; ending above in а twisted scabrous point; smooth above, except near the 
margins and midrib where there are scabrous рарШе, smooth below, edges scabrous; 
main vein narrow shining below, secondary veins not prominent, 7 to 8, with usually 7 
intermediate; leaf-sheath striate, soft, ending in а pair of shining calluses with a depression 
between, one often rounded, short, the other long, almost acute, slightly produced at the 
mouth to meet the ligule; ligule long, serrate. Inflorescence a large panicle of spicate 
branchlets bearing globular heads of many spikelets, the heads about 1°5 in. apart 
and 15 to 2 in. in diameter; rachis soft, striate, fistular. Spikelets °7 to 78 in. long 
by '1 to 2 in. broad, 8-flowered, mucronate, glabrous except on the edges of the palea; 
empty glumes 2, 2 to “4 in. long, ovate, mucronate, many-nerved ; flowering glume "6 to 
"7 in. long, mucronate, that of lowest flower longer that the next; palea 2-keeled, 
ciliate on the keels, obtuse, 3-nerved between keels, that of uppermost flower only 
.grooved on the back above and there ciliate, acute; terminal rachilla ciliate, with а 
short setaceous imperfect flower. Stamens exserted, tube thick when young, anther 
apiculate. Ovary ovoid-acute, hairy, surmounted by a hairy style dividing into 3 small 
sub-plumose stigmas. Caryopsis linear-oblong, “4 in. long, crowned by the hairy persis- 
tent enlarged base of the style, grooved on one side, embryo conspicuous. 
Western Ghats of Travancore: “grows only on steep precipitous pase ind wet 
rocks at. elevations of 3,000 to 4,000 ft."—J. F. Bourdillon., | 
_ This interesting species is at once recognizable from: the rest by its soft texture, 
leathery sheath, the curious calluses оп the leaf sheath, and the long 3-flowered spike- 
let. Тһе flowers seem to be all hermaphrodite, Ше. uppermost only. producing seed; 
but the available Specimens are rather old, and many spikelets have had. to be examined 
to find the stamens. It was first collected in flower by J. Е. Bourdillon in 1889, 
and I obtained. specimens through the kindness of Mr. M. A. Lawson, the Director. 
of the Botaujeal Department in. South India. Afterwards, Mr. Bourdillon kindly pro- 
eured ше the leaves and culm-sheaths, and I have great pleasure in associating his 
name with his discoyery. Judging by the culm-sheaths, the culms must reach 2 in.
