Very closely resemljles Dryopteris Sabcei C. Cir. in its lialjit, frond-textm-e 

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

 shable from it hy the structm-e of the scales and venation of the i:iinnules. 



Tliis is one of the ferns which are represented iu Japau hy closely allied 

 species. Among them, I may mention Dryopteris jiseudo-Sieholdii Hat. for 

 D. Sieholdii O. Ktze., D. quadripinnata Hat. for D. Miqueliana C. Ch., D. 

 fluvialis Hat. for D. sen-ulato-dentata 3Ilc. and the present fern f ir D. Sabcei 

 C. Ch. 



Dryopteris reflexipinna Hatata Ic. Pl. Formos. IV. p. 174, (Fig. 113). 



Very distinct species for its zizag flexuose rhachis and reflexed pinuis. 

 Somewhat resemhles Lastrea undulata TnwArrES, (Bedd. Fern. South Ind. t. 

 271), but greatly difiers from it by the herbaceous membranaceous fronds 

 and obtusely lobed pinnules. D. reflexipinna Hatata resembles D. Slaximo- 

 wiczii in its textm-e and habit, while it comes near D. undulata in its reflexed 

 pinnaj.
