13 . ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
veinlets many, prominent, regular, raised beneath with many pellucid glands; Жај-зћеа 
striate, densely tawny-pubescent, at length glabrous, ciliate on the edges, ending in 
a shortly ciliate callus, and furnished with a few long stiff hairy curved bristles; ligule 
short, hairy, often fimbriate. Inflorescence a branched panicle ending in a leafy 
branchlet, the nodes of the panicle subtended by sheathing papery bracts; rachis striate, 
flattened on one side and bearing a.vertical line of close pubescence, the end joints 
hairy, slender, clavate. Spikelets 2 {о 8 in. long, subtended by straw-coloured glabrous 
narrow bracts; rachille very prominent, about :2 in. long, curved, flattened, glabrous; 
flowers 6 to 12; empty glumes 2, short, glabrous, ovate-acute, 1- to 3-nerved; flowering 
glume ovate, acute, mucronate, ciliate at apex, 3- to 7-nerved; pales acute, 2-keeled, 
thickly pubescent, keels ciliate. odicules 3, ovate, faintly nerved,. fimbriate, one 
smaller. Stamens slightly exserted, anthers short, blunt. Ovary ovate, glabrous; style 
short, speedily dividing into 2 shortly plumose stigmas, Caryopsis not known. 
Eastern Himalaya and Khasia Hills in Assam, up to 6,500 feet; collected in 1850 
by Hooker at Moflong and Myrung, 6,000 feet; by.C. B. Clarke, in flower, in Shillong 
-ood (No. 37431), in March 1885; by С. Mann at Shillong peak in 1873 and at 
Myrung іп 1890; and by J. L. Lister in 1875 ш Ше Duphla Hills at Shergarh 6,800 
feet and Singook 4,500 feet. | 
This species is easily distinguished from all others, except А. Grifithiana, by its 
spinous nodes, and ош that species by the different inflorescence, longer and 
broader leaves, and less hairy and .thinner sheaths. It grows in open clumps in 
evergreen forests, and is. used for tying on the thatch of native houses. Hooker 
gives Ше Khasia name Uskong, while G, Mann gives those of U-spar, spar. For the 
flowers, which were unknown when Munro wrote, we are indebted to С. B. Clarke. 
Listers specimens show excellently the characters of the culms and culm-sheaths.

SECTION П. 
11. ARUNDINARIA FALCATA, Nees in Linnea ix. 478 (1834). 
А gregarious shrub with annual culms from a central rootstock. Culms 6 to 10 ft. 
high, *3 to *6 in. in diameter, smooth, cylindric, green at first, and sometimes white 
pruinose; nodes much swollen, glabrous or hirsute; internodes 6 to 12 inches long, 
smooth, walls thin; branchlets from the nodes fasciculate, very numerous, slender, 
geniculate at the joints; flowering and leaf-bearing branches on different culms, 
Culm-sheaths papery, straw-coloured, striate, as long as or longer than the internodes, 
often 12 in. long and 3 in. broad at the base, glabrous above, ` minutely scab- 
rous, hairy beneath in the upper half; ciliate on the edges; gradually and con- 
cavely attenuate upwards in the upper two-thirds to a narrow, truncate, ciliate, "1 to 
'2 in. broad tip; imperfect blade "5 to 2 in. long, “1 in. broad, subulate, recurved; 
ligule elongate, often 5 in. long, dentate. Leaves usually З to 4 in. long and :2 to '3 
in. broad; exceptionally (on young shoots) up to 12 in. long and 1 in, in
