EOCENE FERNS.

Davallice, but no known Fern resembles it so closely as Anemia adiantifolia} Sw., an 

 inhabitant of Cuba, Bahamas, Florida, and Mexico to Eahia. 



Saporta has kindly compared specimens from Bournemouth with those of Sezanne, 

 and writes respecting them, " Je n'hesitc pas a declarer qu'il s'agit ctune seule et meme 

 espece." Lesquereux, to whom we are much indebted, has also compared Bourne- 

 mouth specimens with those from the Eocene of North America, and has written, " I do 

 not see any difference whatever." 



Asplenium Fcersteii, Deb. and Ett., described in the ' Urweltliche Acrobryen des 

 Kreidegebirges von Aachen,' pi. ii, figs. 4, 7, 11, is also closely related to, if not 

 identical with, A. subcretacea. De Bey sees in them a close resemblance, but not 

 identity. The specimens figured by Heer in the ' Kreide-Fl. der Arct.-Zone,' p. 93, 

 pi. xxvi, fig. 1, as A. Foersteri, seem to belong to quite a different species, and Dr. 

 De Bey writes that this and other identifications were made without any comparison 

 with his specimens. 



This Fern is found more especially to the east of Bournemouth Pier, and 

 appears to have attained its greatest luxuriance when growing with Aroids and Conifers. 

 It decreases in size and abundance in the beds westward, towards Poole Harbour, 

 and at Branksea small pinnse only are met with, such as are drawn on PI. IX, figs. 

 3 and 5. The specimen, pi. vi, fig. 6, ' Lignites of Bovey Tracey,' from Bovey, may 

 belong to this species. Heer is confident that he has seen it from Alum Bay, but it may 

 possibly have been erroneously labelled. 



A fragment of this Fern, probably the one just alluded to, was named Asplenium 

 Martinsi by Heer, but not figured, and has been referred to in several subsequent 

 works.
