I have since found this common among coral and mud banks 
round the Pulo Bissar, and in abundance in the small /agoon of 
Pulo Pangang, generally very small, only reaching а tolerable 
size where the lowest ebb water is 2 or 3 feet deep. 
The Rhizoma is firmly creeping, covered with stout black 
bristly fibres. Radicles simple, stout, cellular spongy fibrilloso 
hairy. 
It is also rather hairy from the lateral fibres of the leaves 
being persistent. 
The stalk of the fruit is spirally bent; in the lagoon, 
where fruit specimens were found, it was sub-immersed at the 
lowest ebb, and erect. The dehiscence is deliquescent as in 
Nymphæa, the pericarp breaking up irregularly, its substance 
farinaceo-spongy, seeds green mucilaginous or slippery from 
adhering part of pericarp germinating in the capsule, that is 
the plumula is exserted, although the radicle is not lengthened. 
No flowering specimens found, it is rare even in fruit. 
Pulo Pangang, Sept. 22nd, 1842. This is not an estuary 
plant here.
