hdda, and consequently sometimes
but the very characteristic culmslieaths,
the narrow leaves, and the attemiate ovary really at once distinguish it. Flowering
specimens were collccted by Hooker and Thomson in Eastern Bengal in 1850 on
cultivated plants ; and, so far as I am aware, it has not again been found in flower
till collected in the Barduar forest, Kamnip, Assam, in 1890 by Paniram Dás for
G. Mann. These specimens bear the native name i'/w/íaí (i\.ssamese). Leaf specimens were
collccted also by Hooker and Thomson in Cachar (native name Biivtval, huJchal), and at
Jowye, Khasia Hills, 3,500 feet (native name Uskan, Kliasia). Besides the llowerinospecimens
referred to above, I identify as this the folio n-iug with only leaves and culmsheaths
sent by G-, Mann from Assam in 1890 : from Sibsagar (cultivated under names
WalUhai (Assamese), Wafoi (Xaga}; from Kakadanga river, Noga Hiilg (wild), under names
WalUhai (Assamese), Tesero (Naga) ; from the foot of the Mikir Hills (wild) under names
Jma (Assamese), Loto (Mikir) ; from Shillong, Khasia Hills, (cultivated) iinder names UsJcen,
seskien, shhcn (Khasia) ; from Jowai, 4,000 feet, and Sundai Hill in the Jaintia Hills under
names Uslcen, slclien, innvg (Khasia); from Charduar forest, Darrang district, under name
Byli (Assamese). I also identify as this species the bamboo collected by myself in 1880
in British Bliutan in the Reyoong and Rilli valleys at 3,000 feet under the name Pshi
(Lepcha) ; that collected by T. Anderson in the Tecsta valley, 600 to 1,500 feet, in
1868, and called Fushee ; that collected by Kin-z in the Great Uangit valley under the
same name ; and that found at Pedong, 3,000 feet, under the name Bongshing (Bhutia) ;
as -svell as the one collected by G. A. Gammie at Mongpoo under the name Paskijio
(Lepcha); and I find that on T. Anderson's specimens in Calcutta Herbarium, Munro
has noted them as ' v e i y like B. pallida.'' I also identify as this a specimen (No. 273)
from the Dikrung valley, Daphla Hills, found by J. L. Lister in 18T4. Finally, it has
recently been received from J. W. Oliver from the moist, evergreen forests of the Bhamo
disti'ict, Upper Bm-ma, at 800 feet, under the names Ggawu. (Burmese), Madanh-an, maipyu
(Kachin); and after carefully reading Km-z' description in tlie Fnrost Flora of Burma and
examining his specimens and his di-awing of the culm-sheath, I conclude that liis
Dendrocalamiis criticus from the Kambalataung, the highest point of the Pegu Yoma
Range, is in all probability tliis species also. In Assam it is used for many purposes—
for building, for making baskets and mats and for ves.scls to hold water.

Tbk is usually a shrubby species, in habit not unlike B. lineal«, but the spikelets,
which unfortunately I have never been able to examine, are very diflercnt. Munro,
cniotino- Brandis, wbo obtained it in flower m the YSnzalin valley under the name
TItealm, describes it as scandcnt; but Kurz, wbo must have known it growmg, calls it
a low bushy species, and this is the char-aeter it shows in cultivation m Calcutta,
whore it is common in the Botanic Garden on the edge of the muddy river bank.
Ivurz gives the name ' Thailma, ' the same as that of B. TuUa and B. hwmmica. I
regret that I am unable to figure the flowers.
