* Signifies that the form is almost specifically indistinguishable from existing species, -j- Indicates 
that the fossil species has only been met with in England. ... That the form is represented by a less 
closely allied species. 1, 2, 3, are Aix-la-Chapelle species. 4, L. Kargii, Reer, of Oeningen. 5, W. 
latiloba, Lesq. 6, W. venosa. The allied species are enclosed in ( ). 
The above table comprises fifteen species, which have been described from such exceptionally ample 
and well-preserved specimens that it seems unlikely that doubt can arise respecting the accuracy of their 
determination. The list might have been extended, yet even as it stands no striking group is omitted 
except the Tree-ferns of Sezanne, and it is thus remarkable that nearly all the distinctive forms and those 
of most value for comparison should belong to our British Eocene flora. Compared with the total number 
of existing Ferns they appear very few ; yet, contrasted with the present fern-flora of North America, 
which contains but fifty species, with that of Europe, which possesses but sixty, or still more so with 
that of Great Britain, which has but thirty-six, their number does not appear insignificant.
