INDIAN BAMBUSE.E ; GAMBLE. 37 
Eastern Bengal and Burma. А common species in the upper mixed forests of the 
Pegu Yomah and Martaban, often associated with teak, extending north-westwards into 
Sylhet. 
This species was originally collected in flower by Brandis in 1862, in Zamayi forests, 
and afterwards by Kurz at Thaukyegat in 1871. It is also said to have recently 
flowered in the Bassein forests. It is known locally as Kyathaungwa (Burmese) апа 
is considered the best kind for the walls, floor and roofs of houses in Lower Burma. 
It is cultivated in the Calcutta Botanic Garden (No. 6 in the bamboo grove) and 
though apparently it is so common a species in Burma, it is strange that it has been 
so seldom collected. The flowering panicles resemble at first sight those of В. arundinacea, 
but its chief characteristics are the very much ciliate, wavy-auricled and appressed white 
hairy sheaths, the small leaves, and absence of cilie to the palea. Munro speaks of the 
flowers being moncecious or even diceious, but the many spikelets I have examined have all 
proved hermaphrodite. С. Mann's specimens from Protabgarh, Sylhet, called Betuá and 
Jáma betuá (Bengali) belong, I consider, to tbis species.

7. BAMBUSA PALLIDA, Munro in Trans. Linn, Soc. xxvi. 97. 
A graceful bamboo growing in thick clumps, Culms 40 to 60 ft. high, 2 to 3 in. 
in diameter, very smooth, olive green, the young shóots covered with white powder ; 
nodes not very prominent; internodes 18 to 30 in. long, walls thin. Cudm-sheaths 
7 to 12 in. long, about 10. in. broad, usually only little attenuate upwards, and very 
straightly truncate at top, only when young somewhat roundedly truncate, glabrous 
or covered with appressed white hairs when young; imperfect blade very long, usual. 
ly longer than the sheath, often 14 in. triangular-acuminate from a broad base 
which covers nearly the whole top of the sheath, slightly rounded at the edges and 
then furnished with quite small rounded auricles, the auricles and lower part of the 
margins furnished with bristles ; sparsely appressed black hairy without, glabrous or 
slightly hairy within; ligule very narrow. Leaves linear-lanceolate, 4 to 8 in. long, 
“5 to "8 in. broad, rounded or subcuneate at the base, with a very short, hardly :1 
in. long petiole; furnished above with a subulate, twisted, scabrous point; glabrous 
above, except for the scabrous marginal veins, pale, often nearly white and hirsute 
beneath ; scabrous on the margins; main veins conspicuous, shining, secondary veins 
4 to 6, rarely more, intermediate 7 to 9; lea/-sheaths glabrous, striate, ending in a 
prominent smooth callus, and furnished with a rounded erect auricle fringed with a 
few stiff long bristles, and quickly deciduous; ligule very short. Inflorescence a large 
branching, very pale panicle, with spicate branchlets bearing heads with many sterile 
and few fertile pale spikelets; rachis fistular, that of branchlets slender, wiry, glabrous. 
Spikelets pale, 1 to 1:3 in. long, sometimes curved, bearing usually 1 to 2 small ovate- 
acute empty glumes, then 1 male or gemmiparous glume, then 3 to 8 fertile flowers, 
then 3 to 5 imperfect ones gradually decreasing in size; rachilla short, club-shaped,
