Generally spread. 



1 l»r Dickie states (Journ. Linn. Soc. Lond., xiii. p. 178) that Mr Melliss sent him the root and part of the 

 stem of a large species several feet in length, which is cast ashore in a battered condition on the southern side of 

 the island. From its structure Dr Dickie supposed it to be the EcMonia hurcinalis, Hornem., a common species 

 at the Cape of Good Hope, whence, it doubtless drifted to St Helena, as a strong current prevails from that part.
