TAKEDA—ASIATIC POLYPODIUMS. 271 
volutae. Sori in parte frondis apicali continentes. Paleae 
rhizomatis ut in a, sed plerumque breviores. 
Distr.—Japonia, Corea, et China 
This variety is characterised by the small frond with roundish 
apex. It is sometimes difficult to distinguish it from a dwarf 
form of a. This plant was described from Japan by Franchet 
and Savatier as P. Onoei, and has been rightly reduced by 
Makino to P. lineare as a variety. 
This variety had not been recorded from China until 1902, 
when Christ described it as P. lineare var. abbreviatum. There 
are at Kew and in the British Museum specimens of the identical 
plant collected by Harland in Hongkong, and labelled Drynaria 
subspathulata, Hook. Although these particular specimens did 
not form the basis of Hooker’s description, they agree very well 
with the diagnosis. Harland’s specimens are referred to by 
Bentham in his Flora Hongkongensis, but this author, instead 
of using Hooker’s name, regards it as a synonym of Polypodium 
Wightianum, Wall. His description given for P. Wightianum 
in his book is, however, partly of P. Wightianum, Wall. (=P. 
nudum, Kze.) and partly of our plant. 
From China I have seen the following specimens :— 
Hongkong (Harland, 1857) ; Chekiang: hill west of Huchow 
(Carles, n. 188) ; Kiangsu: Shanghai (Maingay, n. 452).
