Mr. Medley Wood identified the seeds in which the 

 specimens from Tongaat were found as belonging to an 

 Indian species of Barringtonia (B. speciosa), Avhich 

 always occurs by the sea-coast and on the borders of estuaries 

 and lagoons, and is very plentiful in India. These seeds are 

 " occasionally cast up on the beach, and in some cases the 

 shelly tubes fill the whole space formerly occupied by the 

 kernel" (Burnup).
