FLORA OF THE SUNDRIBUNS. 
361 
wherever a mud-bank drops suddenly into deep water a line of Myriostachya 
I marks the river-margin of the field. The Myriostachya, however, very 
often occurs in localities where Oryza does not, and forms a fringe of reed-like 
j grass close up to the true forest. Though generally distributed from the northern 
I borders to the sea- face it appears nowhere to be very plentiful. 
The species is doubtfully reported from S. India in the Flora of British India, 
I but the only specimen of the grass from Wight’s herbarium seen by the writer 
^ appears to have come from Mergui. The species has been also reported from 
' Langkawi south of Tenasserim and has been collected by Mr. C. Curtis both in 
Penang and in Province Wellesley.

A tall tufted grass. 
Distrib.— Tropics of Eastern Hemisphere and Australia. 
There is in the Calcutta Herbarium a Sundribun specimen of this grass, 
collected in 1845; it has been reported since. It is a grass the occurrence 
of which in the northern clearings would not cause surprise % it should therefore 
be looked for, with a view to confirming this old record.

‘‘Delta of the Ganges,” Roxburgh (1795), 
Of this fern, obtained from the Sundribuns, Roxburgh has left a coloured 
drawing which shows that it must be very nearly related to P. longifolia Linn. 
(P, amplexicaulis Roxb.). 
Roxburgh, however, distinguishes the two very carefully as follows : — 
P. ; stipes rising singly from a creeping stem, long and polished; 
pinnae not enlarging into a stipe-clasping base, tapering to a very 
long fine point and (generally) fertile for only about two-thirds their 
length.
