90 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
scabrous; main vein thick, prominent, yellow, shining beneath, secondary veins 8 to 10 
on either side, not prominent, intermediate 6 to 7; leaf-sheaths smooth, glabrous, somewhat 
produced at the mouth, and sometimes bearing a rounded naked auricle on one side ; 
ligule narrow, usually fringed. Inflorescence a large panicle of interruptedly spicate clusters 
of spikelets, sometimes leafy; rachis flexuose, flattened on alternate sides, '5 to 1:5 in. 
between clusters, glaucous-green, sometimes rough. Spikelets in heads sometimes few-flow- 
ered and 2 to *3 in. broad, supported by hard polished bracts, sometimes many-flowered 
and 5 to ‘7 in. broad; blunt, nearly glabrous, 2 to "8 in. long; empty glumes 2 to 3, 
obovate, blunt, with short rachille between; flowers 2 to 9, fertile; flowering glume 
blunt, obovate, cucullate, ciliate on the edges, many-nerved ; palea oval, truncate, faintly 
keeled, 2-nerved between the keels, faintly pubescent, Stamens short; anther yellow, 
short, ending in a black mucronate point; filaments short. Ovary broadly ovoid, somewhat 
acute, hairy, ending in a rather short style and short purple stigma. Caryopsis ovoid, 
somewhat oblique, yellow, surmounted by a beak formed by the base of the style. 
BAMBUSA LoNGISPATHA, Kurz їп Journal As. Soc. Beng. xli. 949. 
Eastern Bengal and Burma, chiefly along streams. Sent from Sylhet by G. Mann 
in 1889; collected in Chittagong by J. L. Lister, 1876, by myself in 1879 and 1880, 
and by R. Ellis in 1885; in Arracan by W. Schlich; and in Burma by Brandis 
(1862); Киз (1871); P. J. Carter (1891) and others. 
This handsome species is at once recognized by its long fragile papery sheaths and 
by the large panicles of small flower heads and blunt spikelets. It comes nearest to 
D. Нат опа in its general characters, but is easily recognized therefrom. It flowered 
in Chittagong in 1876 (Lister) and 1879-80 (Gamble) and in Burma in 1871 
(Kurz) and . 1891 (Carter) It is known locally by the names Khang (Bengali), 
Ora (Ax ) and Wa-ya and Talagu (Burmese), the name * Wa-ya’ meaning ‘stinging 
bamboo, for the hairs on the sheaths are especially irritating. It has been introduced 
into the Western Peninsula and cultivated at Calcutta, in Malabar, ete., but the culms 
are not very strong, and as a building material it is generally inferior to many 
other kinds.
