[Under the name A. preslianum, Fée, syn. A. ciliatum, Presl, Fournier, including his 
citations, has a mixture of that species and A. simplex, Swartz, and A. flaccidum, Fée; 
the figure in Hooker and Bauer’s ‘ Genera Filicum,’ t. 105, being, as Mr. Baker informs 
us, A. flaccidum and not A. simplex. A. ciliatum is totally different from both of the 
others, and only A. simplex occurs within our limits. |
