1. Terrvosracnyum GRIFFITHH, Munro in Trans. Linn. Soc. xxvi. 143, Zab. 3. 
A graceful, straggling or sub-scandent, bamboo. Culms erect at first, afterwards droop- 
ing, 25 to 50 feet long, verticillately branched from the nodes; internodes 18 to 26 in. 
long, “6 to "8 in. in diameter, scabrous above; walls thin, 2 in.  Culm-sheaths 6 in. or 
more long, 15 in. broad, glabrous and shining below, covered above with appressed 
white hairs, ciliate at the edges, strongly convolute; imperfect blade 3 to 4 in. long, 
reflexed, ovate-acuminate, rounded at base and prolonged into a large rounded auricle at 
either side, Ше auricle and base of the imperfect blade fringed with long, curved, reflexed 
bristles, the inside densely white-shaggy, transverse veinlets conspicuous; ligule short, 
pubescent. Leaves oblong-lanceolate, 6 to 10 iu. long by ‘7 to 15 in. broad, glaucous 
beneath; rounded at the base into a thick wrinkled petiole 2 in. long; cuspidate 
above with a scabrous, subulate point; scabrous on both edges, glabrous on both sides 
"except for clusters of long hairs at the base of the midrib; main vein conspicuous, 
pale, secondary veins 8 to 10 pairs, intermediate 7, thick, transverse veinlets none, 
but occasional pellucid glands, which appear like transverse veinlets on the under sur- 
face ; leaf-sheaths striate, keeled, ciliate on the edges, glabrous or appressed, pubescent, 
ending in a narrow callus, and bearing at the mouth two long falcate auricles fringed 
with stiff deciduous ciliz, “2 to -4 in. long; ligule short, fringed with cili; like the 
auricles, Inflorescence a leafy panicle bearing at the verticils short spikes or single 
spikelets, often long, whip-like, with few spikelets on a filiform rachis; rachis ordi- 
narily smooth, striate, swollen at the joints. Spikelets very narrow, linear, 2 to 3 
in. long, about :2 in. broad, often pedicelled, minutely pubescent, with Ө to 5 fertile 
flowers and usually one or more sterile both above and below; rachilla smooth, 
jointed below the flowers, swollen at the joints; empty glumes 1l or 2, the second then 
bearing a sterile flower, 79 to 4 in. long, narrow, striate, ovate-mucronate; Jlowering 
уште “5 in. long, ovate-acute, mucronate, 9—11-nerved, pubescent; palea rather longer 
than flowering glume, 2-keeled, the keels edged half way down with a wavy fringe, 
ciliate near the tip, 4-nerved on either side, faintly purple-mueronate. ZLodicules ovate- 
lanceolate, concave, equal, quite glabrous, 7- to 9-nerved, often thickened at the base 
which is then darker in colour, Stamens exserted, filaments narrow; anthers yellow, blunt, 
or emarginate. Ovary stalked, glabrous, ovate, narrowing into a long triquetrous beak 
forming the style, surmounted by 2 to З white or purplish stigmas. ^ Caryopsis 
obliquely ovoid, glossy, tapering at both ends, ending in a long stiff beak. ^ CEPHALOSTACHYUM

Bhutan (?) Assam, Chittagong and Burma. Collected by Griffith in the forests 
of Wullaboom in hilly country, also in the Khasia Hills. Found in Assam, in Sibsagur 
and Dibrugarh, by С. Mann, in 1889 (flowers) and 1890. dus 
The long narrow spikelets in axillary fascicles, spikes or short panicles, are very | 
characteristic. Тһе specimens sent by G. Mann bear the Assamese name of Вей“, бей, 
and the plants were said to have grown in low damp places in Ше plains. То this
