There is some doubt whether this fern was collected in St Helena, for the specimen is 

 without an original label, and no other traveller has collected it in the island so far as we 

 are aware. Melliss omits all mention of it. 



| Asplenium marinum,Lmn., is recorded by Moore (Ind. Fil, ii. p. 114) as occurring 

 in St Helena and the Bermudas, but we have seen no specimens of it from either place, 

 and the record was most likely based upon a mistake.]
