22 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUITA. 
This graceful little climbing bamboo has 6 stamens, and, under the impression 
that the character given by Bentham and Hooker to the section Triglossee was 
permanent, I described it as a new genus, Microcalamus, in 1890. It appears, however, 
from а note by Professor D. Oliver to plate 1969 of Hookers ‘Icones Plantarum,’ 
that not only was the name Microcalamus already pre-occupied, but that the authorities 
at Kew saw nothing to prevent bamboos having the other characters of Arundinaria 
being described under that genus in spite of a larger number of stamens, so that I 
do not hesitate now to transfer my plant to Arundinaria, I cannot, however, agree 
with Professor Oliver in referring A. Praini? to А. kurilensis, Ruprecht; for I can trace 
no points of agreement except those of the 6 stamens and spikelets with about the 
same number of distichous flowers. G. Mann gives Ше Naga name as Sampit, and 
says that the plant is used for basket-work and for building huts. Mr. Rollo gives 
the Naga name Кора,

SPECIES OF WHICH THE FLOWERS: ARE NOT KNOWN. 
19. ARUNDINARIA MICROPHYLLA, Munro in Trans. Linn. Soc. xxvi. 32. 
A gregarious, low, cæspitose shrub. Culms 2 to 4 ft, high; internodes 2 to 3 in. 
long, very glabrous; branches many from the nodes, semi-verticillate. ^ Culm-sheaths 
not known. Leaves small, narrow, linear-lanceolate or almost lanceolate, acute, “1 to “2 
in broad, under 1 in. long, shortly mucronate, the margin almost membranaceous, 
fimbriate or glabrous; /eaf-sheath often dark-coloured, striate, hairy above, long fimbriate 
at the top; secondary veins 2 pairs, hardly conspicuous, transverse veinlets many, 
not raised; ligule scarcely visible. BAMBUSA MICROPHYLLA, Griffith Journ. i. 242, 259, &c. 
Bhutan: collected by Griffith at Sanah, 7,000 ft., and at other places between 
6,000 and 10,000 ft. ` 
t is possible that C. B. Clarkes No. 38980, collected at Soyung, 5,000 ft., 
Khasia Hills, in 1885, described as dwarf, and said to be used for pony fodder, may 
be this species, but the leaves are larger. Griffith describes A. microphylla as a dwarf 
plant, ‘forming large patches in wet places’ and clothing the sward on the Dhong- 
laila Pass at 10,000 ft. 
No plate available—description after Munro. 
20. ARUNDINARIA HIRSUTA, Munro in Trans. Linn. Soc. xxvi. 30. 
A small shrubby bamboo with single stems from the rhizome. Culms greyish- 
green, 4 to 8 ft. high, 2 to 3 in. in diameter, nodes glabrous, raised; internodes up to 
13 in. long, often. strigosely hirsute above, walls rather thin. Culm-sheaths thin, papery, 
about 6 in. long and 1 in. broad at base, striate, covered with long brown hairs, 
контра at top and ending in large, recurved, long-ciliate auricles; imperfect blade subulate, 
unate, recurved; ligule narrow, pubescent. Leaves oblong-lanceolate, 3 to 5. in. 
long
