CYSTOPTERIS MONTANA. 



Lochey and Glen Dochart, Perthshire, and in Glen Isla, 

 Clova, Forfarshire, and on Belvinnes, Banffshire. 



Native of Scotland, Kamtschatka, Rocky Mountains of North- 

 west America, in the extreme North of Europe, Spain, Italy, 

 Hungary, Lapland, Norway, and on the Alps. 



Fronds triangular and tripinnate; pinnse spreading, the pin- 

 nules being oblong-obtuse; segments blunt and inciso-dentate. 



Fronds lateral or terminal, and adherent to a long slender 

 creeping rhizoma. 



Stipes half the length of the frond, and frequently more; 

 slightly scaly. 



Sori minute, circular, and becoming confluent. 



Length of frond from four to twelve inches; colour a lively 

 green. 



To grow this Fern successfully plant it in a shallow pan, 

 with a mixture of peat, sphagnum, and sand, giving it an 

 open medium for its roots, a moist shady place to grow in, 

 and water freely. In a wild state it grows on ledges of 

 dripping rocks, amongst sphagnum. 



For plants my obligations are due to Mr. Atkins, of Pains- 

 wick; Messrs. RoUisson, of Tooting; and Messrs. Backhouse, 

 of York; and for fronds to Professor Balfour, of Edinburgh. 



It may be procured of Messrs. Kennedy, of Covent Garden ; 

 Veitch, of Chelsea; Sim, of Foot's Cray; A. Henderson, of 

 Pine-apple Place; and Stansfield, of Todmorden. 



The illustration is from Professor Balfour's frond.
