Tristan da Cunha. — Without locality — Carmichael ; Moseley. 



Madagascar ; Mauritius ; Bourbon. 



By an oversight apparently, this species is reduced to Polypodium aquilinum in Hooker's 

 Species Filicum. This arose probably from a mistaken identification of a specimen of 

 Carmichael's collecting, and named by him Polypodium acunhianum, with Nephrodium 

 tomentosum, for we find this name on one of the sheets. Several of Carmichael's ferns bear 

 different manuscript names from those under which they were ultimately published.

 Polypodium calyptratum, Thouars, Esquisse Fl. Trist., p. 33. 



Tristan da Cunha. — On the face of the tableland — Carmichael; without locality — 

 Moseley. 



Widely spread in Tropical and Temperate South America, in Africa, Mascarene Islands, 

 Polynesia, Australia, and New Zealand. 



Carmichael states that he found only one plant, and suggests that it might be a 

 stranger. Moseley collected good specimens ; but the fronds bearing sori were only 

 about four inches high, while a specimen collected in Amsterdam Island by De ITsle is 

 nearly three feet high.
