REPORT ON THE BOTANY OF THE ISLANDS OF THE SOUTHERN OCEAN. 163 



last of which occurs in Amsterdam Island, as well as South Africa, the Sandwich Islands, 

 and New Guinea, Kuhn records it from the Cape of Good Hope (" Hb. Hooker "), but 

 this probably arose from a misreading of Mettenius's notes.

Tristan da Cunha.— On rocks — Carmichael; in boggy ground— MacGillivray and 

 Milne. 



Common in Tropical America, from Mexico to Peru and Brazil. There are copious 

 specimens of this fern in Kew Herbarium from Tristan da Cunha, yet Mr Moseley did not 

 collect it in either of the islands ; therefore we presume it must be rare. Kuhn retains 

 the Tristan da Cunha plant as specifically distinct from the American without giving his 

 reasons ; but we have followed the Synopsis Filicum, as some of the American specimens 

 are so like the insular ones as to be undistinguishable from them, by external characters 

 at least.
