TRISTAN DA Cukha. — Endemic. High on the face of the tableland, and on a 

 detached hill in the middle of the plain — Carmichael. 



Of this very distinct fern we have only seen the specimens collected by Carmichael. 

 Swartz erroneously, as it would seem, recorded it as a native of the Mauritius, and he has 

 been copied by most subsecpient writers. It must be very rare in Tristan da Cunha, or 

 recent travellers would certainly have collected it, as it is exceedingly elegant, and quite 

 different from anything else in the group.
