POLYPODIACE^. 
Rosshire. — Mr. Watson gives this county on the authority of 
Mr. Wilson. 
Sutherland.' — Mr. Francis gives Sutherland on the authority 
of Dr. Murray. 
In Ireland it is a plant of great rarity, occurring very sparingly, 
and only in three counties which approach those English coun- 
ties, in which it is most abundant. 
Antrim. — Mr. Moore informs me he found a few specimens 
in the liberties of Carrickfergus. 
Down. — Mr. Thompson informs me it was found in the crevi- 
ces of the rocks about the summit of Sleive Bignian, on the 20th 
of August, 1808, by the late Mr. Templeton, Mr. Mackay, and 
Dr. W. Stokes : it is said, in the ‘ Flora Hibernica,’ to be abun- 
dant on the Mourne mountains, but this seems scarcely correct : 
many botanists have been unsuccessful in their search for it, and 
Mr.* Thompson says that after spending ten hours on these 
mountains he could not find a specimen of Allosorus. 
Louth. — Mr. Thompson informs me that in 1836 he obtained 
a single specimen on Carlingford mountain, in this county. 
It has not been observed in Orkney by Mr. Clouston, or in 
Shetland by Mr. Edmonston. 
The geographical range of Allosorus crispus is confined to 
Europe, as far as my information has hitherto extended : it ap- 
pears to occur here and there throughout the continent : it is 
recorded as a native of Sweden, Germany, Hungary, France, 
Italy and Spain. I have seen no corresponding form from North 
America. 
Many characteristic figures of the Rock Parsley may be re- 
ferred to ; those in Bolton’s ^ Filices,’ ^ ‘ Flora Danica,’ f and 
^ English Botany,’ % Ri’u very like the plant. Our old friend, 
Gerarde, the herbalist, appears to have omitted it altogether, but 
Ray has described it as ^Adiantum album crispum alpinum^% 
This species appears to have perplexed botanists greatly, as 
to the genus in which it ought to be placed : Linneus made it 
an Osmunda, but in a MS. note to his own ‘Species Plantarum’ 
he transfers it to Pteris ; our British authors, Hudson, Lightfoot, 
Bolton, and Berkenhout, follow him in his first nomenclature ;
