Very closely resembles Dryopteris Sabcei C. CH. in its habit, frond-texture 

 and colour, in the position of sori and in many other points ; but distingui- 

 shable from it by the structure of the scales and venation of the pinnules. 



This is one of the ferns which are represented in Japan by closely allied 

 species. Among them, I may mention Dryopteris pseudo-Sieboldii HAY. for 

 D. Sieboldii 0. KTZE., D. quadripinnata HAY. for D. Miqueliana C. CH., D. 

 fluvialis HAY. for D. serrulato-dentata Mk. and the present fern for D. Sabcei 

 C. CH. 



Dryopteris reflexipinna HAYATA Ic. PI. Formos. IV. p. 174, (Fig. 113). 



Very distinct species for its zizag flexuose rhachis and reflexed pinna?. 

 Somewhat resembles Lastrea undulata THWAITES, (BEDD. Fern. South Ind. t. 

 271), but greatly differs from it by the herbaceous membra naceous fronds 

 and obtusely lobed pinnules. D. reflexipinna HAYATA resembles D. Maximo- 

 iviczii in its texture and habit, while it comes near D. undulata in its reflexed 

 pinnae.
