Ct/perUSm tRIAMDRlA MONOGYNIA. 207 



Obs. In Bengal this plant, or one exceedingly like it, (for it differs 

 from it only in having three stamens, the culm, leaves, umbels, 

 scales, and seeds being the same) grows on the banks of the Ganges 

 and so low as frequently to be entirely under water during the high 

 tides ; yet it thrives and helps lo bind the banks of the rivers where 

 it grows and is one of those plants that prevent their giving way 

 so much to the rapidity of the stream as they otherwise would do.
