The Parsley Fern. 
63 
thousand four hundred feet in Slieve Bingian, co. Down. Several of the recorded Irish 
localities require confirmation. It is said to have been found near Belfast, but was there 
probably planted. 
On the continent of Europe (to which indeed, with the exception of the British Islands, 
the typical Parsley Fern seems to be confined) it is widely, though by no means universally, 
distributed. It is abundant in Lapland and Finmark, extending to Greenland, and occurs in 
the North of Sweden, and throughout the greater part of Norway. Coming farther south, 
we find it in Hungary and Belgium, though not in great abundance ; on the Swiss Alps, and 
in the sub-alpine parts of Switzerland ; in Lower Austria, Styria, and the Tyrol. It occurs 
in Piedmont and in several parts of France, notably among the mountains of Dauphine and 
in the Pyrenees; crossing these, we find it also in Spain, in the highest region of the Sierra 
Nevada, and ascending to ten thousand feet on the Picacho de Veleta. It seems to be entirely 
absent from Portugal. Going east, we meet with it upon Mount Olympus, and it is recorded as 
occurring in Siberia. This may be regarded as the limit of the Parsley Fern, if we take a 
restricted view of the plant ; but if, as seems most in accordance with the evidence produced, 
we take a more comprehensive view, and include under the same species the Indian Allosorus 
Brunonianus and the American A. acrostichoides , we shall of course take a much more extended 
estimate of its geographical range.
