130 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
abstract of a paper read at the Oxford meeting of the British Association, 1804, pub- 
lished in the Scottish Geographical Magazine, Vol. X, p. 635, by Lieutenant-Colonel 
H. H. Godwin-Austen, had been mentioned as possessing thorns at the nodes of the 
culms. Such a bamboo was found; its spines were short on the upper part of the 
culms, and on the lower part were replaced by long, regular, aérial roots. It proved to 
be Arundinaria Grifithiana, Munro. With these two were also found flowering specimens 
of Arundinaria aristata, Gamble. A. Pantlingi is a very interesting species, whose exact 
position it is difficult to locate. Тһе specimens received are all apparently from  leafless 
culms and bear no trace of spines; otherwise it would come next to A. б” па, from 
which it markedly differs in having different culm-sheaths, larger leaves, longer spikelets, 
and no hairs to the tips of the anthers. In the capillary pedicels with glandular bases 
it resembles A. Wightiana and A. floribunda, while in the structure of the flowers it 
comes near to A. racemosa. But on the whole its nearest relation seems to be А. 
вт Мапа, and if, as is surmised to be the real case, it bears flowers on leafy branches 
and spinous nodes, it will come next to it in the analysis, differing in the characters 
mentioned.

ARUNDINARIA ARMATA, n. sp. Gamble. 
An evergreen shrubby bamboo with single stems arising at intervals from a creeping 
rhizome. Culms green, straight, smooth, very thin-walled, 1 to 18 in. in diameter and 
about 20 ft. high; nodes little raised, bearing in a ring below them a belt of straight 
smooth spines; internodes about 8 in. long. Culm-sheaths thin, papery, striate, 6 to 8 in. 
long, 9:5 to З in. broad at base, tapering convexly upwards to а very narrow '1 to ‘2 in. 
top, smooth above or with a few scattered stiff hairs on the upper half, ciliate on the 
edges; imperfect blade exceedingly small, about "1 in. long, triangular, pubescent; ligule 
very narrow, ciliate. Leaves bright green, oblong-lanceolate, long-acuminate, 6 to 9 in. 
long by "8 to 12 in. broad, narrowed at the base into a ‘1 to ‘2 in. long petiole; tip 
subulate, twisted, scabrous; smooth above, slightly rough beneath, scabrous on the mar- 
gins; main vein narrow, pale, shining, pubescent above, secondary veins 6 pairs, inter- 
mediate 5 to 7, transverse veinlets numerous, raised, irregularly spaced ; leaf-sheuths striate» 
ending in small calluses and bearing few (about 10 to 12) straight stiff bristles; ligule 
very short, ciliate. Inflorescence, &c., unknown. 
Hills of Upper Burma, at 5,500 feet, Bernardmyo. 
I am indebted for specimens of this species to Mr. J. W. Oliver, Conservator of 
Forests, who found it in February 1894. It comes near to Arundinaria callosa, Munro, 
but is quite distinct from that species. It is called Машић by the Shans. 
Prare No. 119.—Arundinaria armata, Gamble. 1, leaf-branch ; 2, culm-sheath—of 
natural size; 8, part of node of culm; 4, leaf-sheath—enlarged (all from J. W. Oliver's 
specimens). | 
BAMBUSA OLIVERIANA, n. sp. Gamble. 
A moderate-sized iufted bamboo. Culms glossy-green, sometimes covered when 
young with whitish scurf, 40 to 45 ft. long, 1 to 2 in. in diameter; internodes
