Naturally, this fern is rather small and has short leaves here in 

 the most northernly place where it is found. It grew, however, in great 

 quantities in rock-clefts together with mosses and other plants, and as 

 the weather was fine and sunny when I collected it, the air was strongly 

 perfumed with its agreeable scent of violets. 



Occurrence. Hayes Sound, outer part, in the Lastraea Valley. 

 Mr. Bay first found it here in a single individual (475) in the autumn 

 of 1898; afterwards I found it there in plenty during the next sum- 

 mer (842).
