40 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
than the base; imperfect blade as long or longer than the sheath, middle portion 
thickened, narrow (1 in. at base) cuspidately acuminate, the sides widened out into 
large inflated membranous wings, broadly rounded on the top of the sheath; Jdigule 
narrow, ‘05 in. long. Leaves pale coloured, 4 to 9 in. long, 1 to 1°5 broad, lanceolate 
or oblong-lanceolate, rounded at base into а 2 to :3 in. petiole; ending above in 
a subulate, setaceous, shaggy point; glabrous on both sides; main veins prominent, 
secondary veins 6 to 8, inconspicuous, intermediate 5 to 7; Jleaf-sheaíhs glabrous, striate, 
ending in a broad callus and a minute auricle furnished with a few long very deci- 
duous slender bristles; gule elongate, truncate. Inflorescence a very elongated panicle, 
with spicate branchlets, bearing distant heads of few spikelets partly short sterile, partly 
long fertile; rachis smooth, rather soft, striate. Spikelets "6 to "8 in. long; at first 
cylindric, then flattened, glabrous, bearing 1 to 4 empty glumes or gemmiparous 
glumes, then 2 to 3 fertile flowers, then 1 to 2 terminal imperfect flowers, rachilla 
striate; empty glumes short, ovate mucronate, darker at edges, glabrous, veins promi- 
nent; flowering glume similar but longer and hairy within at the point, about 11- to 
13-nerved ; palea as long as or longer than the flowering glume, many-nerved, short 
ciliate on the keels. .Lodicules ovate-orbicular, blunt, many-nerved, very shortly fimbriate. 
Stamens with obtuse anthers. Ovary linear-oblong, attenuate into a style with З long 
narrow stigmas. Caryopsis not seen. 
Khasia and Jaintia Hills, Assam, also Manipur. Collected in June 1850 by Hooker 
and Thomson at Jasper Hill, Mahadeb, (No. 496) and at Churra (No. 1097)—2,000 to 
4,000 ft.; leaves and culm-sheaths by G. Mann in 1889 near Jowai and Sundai, 
Jaintia Hills, 1,000 to 4,000 ft. It was also collected in flower by C. B. Clarke at 
Jaintiapur, 1,000 ft., in 1885 (No. 42454), and at Manipur (No. 42322). Thus, the 
known flowering years were 1850 and 1885, 
In describing this species from the specimens at Kew, Munro has taken the culm- 
sheaths on the sheet of Hooker’s No. 496 as. belonging to it, but in reality they 
belong to Arundinaria Griffithiana. Mann’s specimens, which bear the names Serim, бугай 
(Khasia), Титай (Naga), Wa-chiusa (Cachari) Bewar (Mikir), Chaltur (Kuki), consist of 
leaves which agree in every respect with those of Hooker’s specimens; and I have 
therefore no reason to doubt that they, with their extraordinary culm-sheaths, belong 
here. Hooker's specimens bore the native names Tumar, tomar, but those sent by Mann 
as “ Bambusa khasiana-Tumoh (Khasia)" are another species altogether. The remarkable 
sheaths, shaggy tips to the leaves, and long distantly-flowered fistular panicles 
characterize this bamboo, which is said by Mann to be used in ч huts and for 
basket-work in general. |
