greatly subject to putrefaction and charged ^\ith a multitude of 

 insects had they continued exposed to the heat of the sun ; the 

 plant, however, is there considered acrid, and when the droughts 

 set in and the waters are reduced very low, they are overheated 

 and so impregnated with the particles of this vegetable that they 

 occasion bloody fluxes to such as are obliged to use them at 

 those seasons " (Bot. Mag. I.e.). 



Propagated by stolons or runners and will not grow except 

 in fresh w^ater : seen at its best in rivers free from tidal influence. 

 The writer saw a close-gro^\dng mass of it under conditions 

 similar to those described above, in the dry season in a back- 

 water near the Cross River, and at its best floating down the 

 Engenni River, where in a large pot in which water was collected 

 from a native hut a fine lot of it was also seen. On trying to 

 convey a few plants to grow at Old Calabar they seemed to go 

 off by the time the mouth of the Bonny river was reached and 

 did not recover sufficiently to grow.
