^yild, or more usually cultivated, in the Malay Peninsula, and throughout the
Malay Arcliipelago, probably extending northwards to Teuasserim; cultivated in the
Calcutta Botanic Garden.
A species very stiiking from its hght-coloured striped culms. The sheaths somewhat
resemble both those of Gigantochloa Atter and Dcndrocalamus giganteus. Kurz
gives the JIalay names Bamhoo andong, hamboo gonihong, bamboo dyai'ja, also aioie soorat
(Sunda). Ridley's specimen No. 119 collected at Twah, Singapore, and identified by
Hackel, is said to be the Campong bamboo.

A tall gregarious bamboo. .Culms 40 to 80 feet high, 4 to 6 in. in diameter.
Cahn-sheatlts not known. Leaves 12 to 16 in. long, 1 to 1'5 in. broad, linearlanceolate,
often unequal sided; narrowly attenuate at the base into a -2 to '3 in. petiole,
acuminate, the tip with a twisted scabrous point; smooth above, softly hairy pubescent
beneath; scabrous on the edges; main vein rather narrow, secondary veins 8 to 10,
intermediate 7 to 8, transverse veinlets conspicuous, formed by pellucid glands joined
obliquely to the veins on either side; leaf-sheaths densely pubescent, ending above in a
pubescent callus and a small rounded auriclo fringed with a few stiff short bristles, cihate
on the edges; ligule short, hairy. Inflorescence a large compound panicle of curved spicate
branchlets bearing verticils of distichous heads, each head bearing 2 to 5 large fertile

mixed with few small sterile sjnkclets; rachis pubcscent, sinuate, sometimes flattened on
one side, 1 to 8 in. between the heads. Spikelets of three kinds, large ones bearing feriile
flowers, medium-sized bearing merely glumes without paloaj or with only rudimentary
jjalete, and small sterile ones; fertile spücelcts '7 to '9 in. long, 3 to 4 in. broad^
flattened, ovate-acute, densely silvery groy pubescent, bearing 2 to 3 empty glumes, then
3 to 5 fertile flowers, then one imperfect terminal flower; emptg glumes ovate, mucronate,
densely pubescent; floivering glume similar but longer, that of uppermost fertile flower
convolute ; palea shorter than flowering glume, 2-keeled, ciliate on the keels, C-nervcd
between them, bifid at apex, uppermost one less ciliato. Lodicules none. Stamens exserted,
lube thick at first, afterwards elongate, membranous but persistent, anthers light yellow,
narrow, long apiculate. Ocary roiuided, haiiy above, style long, glabrous, ending hi a
bifid white hairy stigma. Caryopsis glabrous, ellipsoid, ending in an obtuse, hairy
truncate top and surmounted by the short persistent base of the style.
Malay Peninsiila, collected by the late Rev. Father Scortechini, also by IL Künstler,
Dr. Iving's collector, at Ulu Kerling and Ulu Sclangore in 1886 (No. 8572), also by
L. Wray, Jimior, in Upper Perak (No. 3433) in 1889.
This must be a fine species. It is said to bo gregarious, foi-ming whole forests on
flats and on the sides of hills at 400 to GOO f t . elevation. "Wray gives the Malay name
as ^Bulu Rayah.' 1 am very glad to be able to dedicate his beautiful, discovery to the
late Father Scortechini, whose admii-able work and boundless energy have done so much to
make known the flora of the Malay Peninsula.

3. Gigantochloa macrostachya. Kurz For. Fl. Burma ii. 557.
A large evergi-een bamboo. Culms 30 to 50 ft. long, dark green when old, glaucous
when young, especially below the nodes, sometimes striped, 2-5 to 4 in. in diameter, fistulöse,
the walls being '2 to -3 in. tliick; nodes scarcely thickened, haiiy; internodcs 16 to 30 in
long, lower ones shorter. Culm-sheaths rather short, 5 to 8 in. long, up to 14 in. broad,
not much narrowed upwards to the truncate top, densely covered with appressed blackish
deciduous hairs, subcihate at the edges ; imperfect blade as long as or shorter than the
sheath renifoi-m, acute, appresscd-hairy beneath, less so above, rounded at the base,
and then again produced into a broad (-5 to 1 in.), wavy, long-fringed band ending in
roimded auricles, sometimes somewhat decurrent; ligule narrow, entire or faintly toothed.
Leaves tliin, lanceolate, 6 to 15 in. long by -5 to 2 in. broad, attenuate or rounded at the
base into a short, 1 in. long, often wiinkled petiole; produced above into a setaceous
scabrous point; ,glabrous above except the scabrous points on the marginal nerves,
whitish and minutely and softly puberulous beneath; scabrous on the margins; main
