 from the side veinlets,and thus appe.irini;- between the mibrib and mari^'in of the pinnules; 

 indusium smootli or oecasionally g"landular (this is best seen wiien the froml is newly 

 developed). In autumn the en-et stipes be^in io weakt-n and ileeay at a point within an 

 inch or two oi the base, allowiuii- the fromls to fall upon the ground. Still umietaehed 

 completely from the rhizome, they lie under the snow over winter and are linally withered 

 up by the tlrouj^ht o[' the lollowiui;- summer, formiiiif a matting" around the j^rowini^ 

 plant ; thus the speeies is usually described .-fs imperfectly evergreen. There are many 

 variations o\ this species, in evei"v countr\- in which it occurs, that can be with difliculty 

 distinguished from each other. The American form, which mostly prevails in Canada 

 (our common wood lern). is known as v.ir. IN rt:i?.MKi)iA. 



\'ar. nii-ArATA has a stouter rhizome, shorter stipes, broad lamina, which is ovate, 

 sub-triangular or oblong-lanceolate ; the basal scales are larger, more abundant, and 

 extend further up the stipe, and some of the larger scales have a very dark stripe or 

 blotch in the centre ; indusium usually (but not alwavs) fringed with stalked gfland.s. 



Common in woods and shady places. Ontario : — Abundant in the woods about 

 King'ston, as Collin's Bay, &c. ; Smith's Falls ; Odessa ; Falls oi Xiag'ara ; Hinchin- 

 brook ; Gananoque Lakes; Farmersville ; Hardwood Creek; Delta; Upper Rideau
