36 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
Upper Burma, in the Katha distriet, found on dry hill slopes. 
This handsome species flowered in 1890, and seeds were largely collected and 
distributed by J. W. Oliver, Conservator of Forests, from which many plants were 
reared at Dehra Dún and elsewhere. Не also sent flowering specimens which were rather 
poor and hardly sufficient for description. The name is Thaikwa or thaikwagyi (?) and it 
is just possible that it may prove to be identical with Bambusa villosula, Kurz. Oliver 
describes it as a large species, considerably larger than В, Тида (also known аз 
Thaikwa).

6. BAMBUSA POLYMORPHA, Munro in Trans. Linn. Soc. xxvi, 98. 
A large evergreen tufted bamboo, sometimes leaf-shedding in dry seasons. Culms 
in dense clumps, 50 to 80 ft. high, 3 to 6 in. in diameter, grey to greyish-green, 
white-scurfy when young; nodes thickened, lower ones fibrous-rooted ; internodes 15 in. 
to 2 ft. long; naked below, much branched above and curving outwards.  Culm-sheaths 
thick, 6 to 7 in. long, 12 to 14 in. broad, covered on the back with densely and closely 
appressed white pubescence, sub-attenuate upwards and curvedly truncate at about 5 to 6 
in. in breadth; imperfect blade reniform, concave, cuspidate, about 3 in. long and much 
broader, the lower part plaited and long ciliate, then rounded at the base and again 
widening into a broad band lining the top of the sheath, and produced beyond it in falcate 
auricles often one upwards, the other down, the whole fringed with long rough bristles; 
ligule narrow, entire. Leaves small, linear, thin, 3 to 7 in. long, “3 to ‘5 in. broad; somewhat 
unequally rounded or attenuate at the base into a very short, hardly *05 in., petiole; ending 
above in a short, subulate, scabrous point; at first hairy on both surfaces, especially 
below, afterwards nearly glabrous; somewhat scabrous above and on the margins and 
main vein; secondary veins 4 to 6 on either side faint, intermediate 7; leaf-sheaths 
keeled, compressed, striate, hairy, ending in a callus and a minute auricle furnished with 
а few long deciduous bristles; ligule very short. Inflorescence a much-branched panicle, 
with curving spikes of frequent heads bearing few spikelets surrounded by brownish, 
glabrous, mucronate, chaffy bracts; rachis smooth, the upper part covered with appressed 
whitish pubescence, ultimate segments very slender, wiry. Spikelets shining, often brownish, 
'4 to 5 in. long, in lower heads 5 to 6, number gradually decreasing upwards, somewhat 
pedicellate and enclosed in a long, curved, glabrous bract; empty glumes 1 to 3, ovate- 
mucronate, then 2 to 3 fertile flowers, then a terminal imperfect flower supported by a 
long, flattened, glabrous rachilla; lowering glumes ovate-mucronate, many-nerved ; palea 
somewhat longer, lanceolate, acute at top, keels not ciliate. Lodicules 3, sub-orbicular, 
short-fimbriate all round, 3—5-nerved, one smaller than the others. Stamens partly 
exserted ; anthers purple, usually blunt, but sometimes apiculate. Ovary obovate, hairy at 
top, style soon dividing into З shortly-white-hairy stigmas. Curyopsis ovate, ‘2 in. long, 
depressed, flattened on one side, rounded on the other, hairy above, ending in a short 
hairy muero formed by the base of the style. Kurz For, Fl. Burma ii. 553.
