A form with narrow fronds, much resembling those of A. mohrioides, 

 found growing in the crevices of rocks. In Canada only known to 

 exist on Mount Albert, Shickshock Mountains, Gaspd, Que., where it 

 was found, at an altitude of about 4000 feet, by Professor Allen, in July 

 1881, and by Professor Macoun, in August 1882. Having been found 

 in Washington Territory, U.S., it is to be looked for in Southern 

 British Columbia.

Aspidium temue, Swartz, Syn. Fil., 58. Pursh, Fl. Am., Sept.,ii., 665. 



A common and very variable species, found in crevices of moist 

 shaded rocks, in rich woods, and sometimes in open wet places. It is 

 one of the most universally distributed of our ferns, appearing in 

 almost every part of the Dominion, growing even on the open prairie 

 in moist places near rocks. It is so variable that the same roots will 

 at different times, or even the same time, produce fronds that might be 

 referred to different ones of the many, so-called, varieties.
