50 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
Spikelets in short spikes subtended by an oblong truncate bract, followed by a small, 
ciliate, keeled bractlet; then come two imperfect spikelets in the axils of lanceolate, 
glabrous glumes, the scale at the base of each spikelet 2-keeled, ciliate; then the fertile 
spikelet; empty glume solitary, ovate-lanceolate, acute, glabrous except the сШа on the 
edges, many-veined, convolute; jlowermg glume ovate-lanceolate, acute, glabrous, many- 
veined; palea equal or rather shorter, 2-keeled, rough or faintly ciliate on the keels, 
bearing between the keels the terminal, 2 in. long, rachilla which is surmounted by a 
narrow imperfect flower as long as itself. Lodicules narrowly elliptic, “15 in. long, 
minutely ciliate. Stamens exserted; anthers glabrous, blunt. Ovary ovate, glabrous, 
gradually attenuated into a very short style which very early divides into 3 long, thin, 
plumose stigmas. Caryopsis oblong, ending in a short cylindric реак, Hooker’s Icones 
Plantarum, Plate 2253. 
Malay. Peninsula, in Perak, found by L, Wray, Jun., on the Gunong Inas mountain, 
at 4,500 to 5,500 feet altitude, near the sources of the Selama and Plus rivers. 
The chief characters of this species are the inflorescence (which is more like that 
of Melocanna or Teinostachyum than Bambusa) and the single fertile flower with rather long 
lodicules. Dr. Stapf considers it to be closely allied to В. Griffithiana, Munro, and to 
the genus Nastus. Ав he correctly remarks, in appearance it resembles Melocanna virgata, 
Munro, but the structure of the spikelet is different. It is clearly a remarkable species, 
and may, when the fruit is obtained, be found to belong to another genus than Bambusa 
or possibly to a new one. It has probably the narrowest culm for its length of almost 
any bamboo known except perhaps Arundinaria Prainü. It is called Buloh versumpitan in 
Malay. In a letter to the Director of the Royal Garden, Kew, quoted in the Kew 
Bulletin, Mr. Wray writes:—“ The plant grows at from 4,500 ft. to nearly 6,000 ft. 
* elevation, generally on the ridges of the hills, The canes are about 1 in. in diameter 
“near the ground and taper away 1014 in. These long thin ends drop down till 
“ they touch the ground, The canes are from 40 to 60 ft. long. They are furnished 
* with whorls of leaves at the upper joints, and, as can be imagined, the bamboo is 
* about the most elegant of its kind...... The joints are over 7 ft. in length. Тһе 
* longest joint of а cane is generally the third or fourth from the ground. Тһе 
“ Semangs use the large-sized canes for the outer case of their blowpipes and the small 
“ ones for the inner tube ...... This appears to grow only in two places in Perak.”
