ALLOSORUS CEISPUS. 37 



Spain, Switzerland, Italy, and Hungary : although it grows 

 abundantly on the Swiss and French Alps, as well as on their 

 immense shoulders which stretch down into Piedmont, it is, 

 like Gymnogramma leptophylla, omitted from Godet's ' Flore 

 du Jtira.' I have seen no corresponding form from the conti- 

 nent of America, nor have I any evidence of its existence m 

 Asia, the plant located in Siberia under this name by Kaulfuss, 

 having been subsequently referred to another species, the AUo- 

 sorus foveolatus of Euprecht, (Beitr. z. Pflanzeck. d. Russ. iii. 

 46). The Eussian habitat at the head of the Gulf of Bothnia, 

 I have omitted as Russian, and inserted as Lapp, adopting the 

 geographical rather than the political position of the station : 

 the species is nevertheless liliely to occur in Eussia proper, al- 

 though unrecorded by the accurate and pains-taking Ledebour, 

 except as Lapp. 



In Britain it is a local rather than a rare fern. 



In Scotland it is scattered over most of the oouuties in spots; more fre- 

 quently ornamenting stone walls at a moderate elevation, than growing on 

 the exposed summits of the hills : the Scotch localities are far too nume- 

 rous to particularize. 



Descending into England, we find it recorded by Dr. Johnston as a na- 

 tive of Berwickshire, and by Mr. Winch as grovdng abundantly on some of 

 the mountams of Northumberland. In Cumberland it is an abundant 

 fern : Mr. Watson, the Kev. G. Binder, the late Mr. S. Gibson, and many 

 other botanists, have obligingly sent me many Cumberland stations, among 

 which I may mention in particular the neighbourhood of Keswick and Der- 

 wentwater, Scawfell Pikes, Helvellyn, Skiddaw, MartindaJe, Ennerdale, 

 and Borrowdale. In Durham, Teesdale is recorded on the authority of 

 Mr. Babington ; and rocks at Cocken and walls near Cronldey Fell in the 

 ' Botanist's Guide.' In Westmoreland, Miss Beever finds it plentifully 

 near Ambleside, and, with her accustomed Uberality, has sent me a series 

 of beautiful specimens : the Rev. Mr. Finder also finds it on the schistose 

 or slate rocks in the same vicinity ; Mr. Hindson finds it at Casterton and 

 Old Hutton ; Mr. Coventry at Morland. From Yorkshire I have received 

 a great number of specimens through the kindness of my friends : the 

 chief stations are Fountain's Fell ; Haworth, near Hahfax ; Wensley 

 Dale; Cronkley Scar; a number of stations in. Teesdale ; many spots on 

 Ingleborough ; Penhill, and about the neighbourhood of Settle. In Lan- 

 cashire it is very abundant. Mr. Simpson informs me that on the Moors 

 near Lancaster it grows at a very slight elevation above the sea-level ; 

 Mr. W. Wilson found it in the same neighbourhood, on the road to the
