Polypodium lineare Hk. et Bak. Syn. Fil. 354 (1868), partim. 
Rhizome scandent, greenish, subglabrous; scales rather sparce at the base of stipe, 
or on the growing tip, brown, ovate, acute, erosed, concolorous, thin, fallen off at last; 
frond uniseriate, about 1.4 cm apart, erect, narrowly linear-lanceolate to broadly linear- 
lanceolate, 1.5-5 cm broad, 30-45 cm long, including the short, wingless stipe, gradually 
attenuate to both ends, entire; texture subcoriaceous, light green, more or less wrinked 
when dried; veins obscure; sovi large, orange-yellow, uniseriate and far apart in the 
narrow-leaved forms (f. typica), but irregularly 1-2-seriate in the broader forms, closer 
to the costa, leaving a broad sterile margin, naked from the beginning. 
Common in the Yangtze Valley and extending southwardly to Kwangtung as well 
as the island Formosa and Japan. 
Type from the islaud Chusan (leg. Fortune) and represents a very narrow-leaved 
form, which appears so similar in general outline to the large form of Polypodium lineare 
Thunberg, that it was subsequently reduced to that species by Hooker and*Baker. P. 
chinense Mett. is partly based upon Fortune’s plant and partly upon the plant collected 
by De Griji from Foochow, Fukien, which latter represents a broad leaved form common 
in South and Southwestern China, known hitherto under half dozen other names as 
cited above. 
Generically, this fern differs from Lepisorus (J. Sm.) Ching in tall scandent habit, 
the inherent tendency for the sori to be irregularly disposed and in the absence of the 
characteristic peltate scales on the sori. For over half a century, this fern has always 
been mistaken by authors for Polyfodium normale Don from the Himalayas and South- 
western China, which differs, above all, in the presence on the back of the rhizome scales 
a large tuft of red setiform bristles.
