This is widely distributed over Japan, e.'ipecially in mountain districts. 

 It differs from the typica (Thunb. Fl. Jap, p. 335, et Icon. pi. Jap. Dec. 

 2, tab. 9 ; Makino Plianerog. et Pterid, Jap. icon, illustr. I. tab. IX) by 

 the more distantly placed and thinner frond, much slender rhizome, and much 

 smaller and deltoid scales. My plant seems to be related to a Chinese 

 Fern Polypodium lineare Thunb. var. contortum Christ (in Baroui et 

 Christ in Nuov. Giorn. bot. italia., Nuov. Ser. IV. 1, 1897, p. 98, tab. I. 

 figs. 3, 3, 3, 3.), from which it differs by not contorting when dried.
