quoted, informs me that all the forms figured in this work are of 
common occurrence to the south of Newcastle, county Down. 
In the Channel islands it is abundant and luxuriant. Mr. H. 
Doubleday, in a letter written on his return from spending a few 
days there, says — At a lovely spot on the southern coast of 
Guernsey, called Petit Bot bay, I found a large cave, from the 
roof of which grew thousands of fronds of Asplenium marinum; 
many of them were two feet, and one thirty inches in length, in- 
cluding the naked part of the stem.” 
Its European range appears limited to the coasts of France 
and Spain : it is very luxuriant in Madeira and Teneritfe, and 
according to Sadler has been found in northern Africa, but I 
have never heard of its occurrence in other countries. 
There is a good figure of this fern in Bolton’s ‘ Filices,’^ 
another in ‘ English Botany ,’f and a third in Hooker’s ^ Flora 
Londinensis.’J 
Among botanists of the present day there is no difference of 
opinion as to its nomenclature : on the continent of Europe it is 
but little known to botanists, and in this country all our authors 
agree in calling it Asplenium marinum. It should however be 
remarked, that the different forms of the northern and southern 
plants, have induced some of our older authors to suppose we 
have two species. The northern plant is the Adiantum majus 
Coriandri folio ^ Adianto vero affine y pediculo pallide rubente of 
Sibbald,§ and also the Adianto vero affinis minor Scotica folio 
ohtuso saturate viridi of the same author, || as quoted in Bay’s 
‘ Synopsis ; ’ H and the Adiantum trapeziforme of Hudson 
and Berkenhout.ft Withering properly referred this sup- 
posed species to Asplenium marinum. The southern plant is 
the Cliamcdfilix marina Anglica of Bauhin§§ and Bay,|||| the 
Filicula petrcsa femina seu Cliamafilix marina Anglica of Ge- 
rarde,1[ IT and the Asplenium marinum of Hudson, Berkenhout, 
and all modern botanists.
