This species is distinguished from 0. nignciUata and 0. aVtoeiliak, by its having
the edges of the glumes not ciKate and by its small leaves. It is known, according
to Brandis, as TseiMos-miiidoo (Bm-mese) ; Wanm (Karen).

South India and Ceylon at from 3,500 to 6,000 feet elevation. It occurs in
abundance in places on the Nilgiris, such as in ravines below Coonoor, Kotagiri,
Slclkunda, Sispara, in the Ochterlony Valley, &c. It is also found in the Anamalai
and the Palghat Hills and the hills of Travancore. It was also collected by Beddome
in Kurnool. I have also specimens from 'Wynaad collected by Mr. Ehodes Morgan,
and specimens from Travancore from J . F. Bourdillon. Trimen's Ceylon specimens came
from Eangula llill, 4,000 feet.
It is at ouce recognized by its whip-like climbing branches and long-ciliate
sheaths. I have examined an immense iTumber of spikelets, but cannot find one wliich
has more than one flower, although Beddome says 1 to 3 are fertile. Beddome says
that in the Anamalais it is called Watte, and that the leaves are used for thatcliiu"-;
I never heard of its being used for any purpose on the Nilgiiis. It is very frequently
in ilower, and I am not sure that it dies down after flowering. Wight's specimens were
collected in Nilgh'is iu 1847 and 1851; C. B. Clarke's at Coonoor in 1870; G. Kiuo-'s
in Ochterlony Valley in 1878; Beddome's in tho Anamalais in I860 and 1871; my own
in various places in 1883 and 1889. In flower it much resembles Dendrocalamus strictvs,
and it is said by Munro to bo this plant which is represented as that species in Plato
70 of Eoxbvu-gh's Coromandel plants; but it must, however, be noted that the Plate does
not show monadelphous stamens. In my opinion it mei'cly represents a poor specimen
of Dendroealamus stricfus.
