A common and widely diffused species in warm countries, in America, as well as in 

 the Old World. By an oversight it is recorded from Tristan da Cunha, Carmichael, in 

 the "Species Filicum." Pleopeltis ensifolia, Carmich., was founded upon a specimen 

 collected by Carmichael at the Cape of Good Hope ; hence, probably, the error.

W lu.'ther regarded as a distinct species or only as a variety of Polypodium punctatum, this 

 has a very wide area of distribution, though it does not appear to be a native of America.
