Mascarene Islands ; South Africa ; Southern Islands, from Tristan da Cunha eastward 

 to the present, and temperate South America. Perhaps also iu Ascension. 



The fern referred to by Sir Joseph Hooker (Journ. Linn, Soc. Lond., xiv. p. 477) as 

 a species of Lomaria is probably Blechnum australe, but we have not been able to find 

 the specimen. It was a fragment of a frond, without fructification, from a root torn up 

 by Commodore Goodenough on the occasion of his hurried visit to Amsterdam Island, and 

 forwarded with the Phylica to Kew by Wykehani Perry, Esq., R.N.. of H.M.S. "Pearl," 

 witli the promise, that if the plant should put forth new fronds, he woidd communicate 

 them. On the other hand, although the island has since been pretty thoroughly botanised, 

 it is possible that Lomaria boryana may exist there. 



Asplenium furcatum, Thunb.

Amsterdam Island. De I'Isle. 



Common and widely diffused in warm countries, including St Helena and South 

 Trinidad. 



Nephrodium villosum, Presl. 



Nephrodium Dillosum, Presl; Hook., Sp. Fil., iv. p. 134, t. 264 ; Hook, and Bak., Synop. Fil. p. 286. 

 Phegopteris bivestita, Fournier in Comptes rendus, 1875, lxxxi. p. 1140, non Mett. 



St Paul Island. Del'Isle. 



A very common fern throughout Tropical America and the West Indies, and extending 

 to the Galapagos, hut not previously recorded from any other part of the world. We 

 have cited the Phegopteris bivestita of Fournier's enumeration as a synonym of this, 

 because a specimen in Kew Herbarium from St Paul Island, collected by De I'Isle, and 

 named Phegopteris bivestita, is certainly not the plant described by Mettenius. Mr 

 Baker is responsible for its being referred to Nephrodium villosum.
