Except only the more compound cutting and the larger breadth of the 

 frond, this species bears entirely the same habit as Ptilopteris Maximowiozii 

 Hance ( = Polypodium Maximowiczii Baker). Perhaps this is an ex- 



traordinary variety of the former species.

 lanceolate, subfalcate, acuminate, cuneate at the base, petioled, often hairy 

 at the axil of the petioles, inferior pinnae more frequently pinnatipartite 

 or pinnate into erect-patent falcate oblong-lanceolate spinescent-pointed- 

 crenate and spinescenfc-tipped pinnules, which are cuneate at the base, middle 

 pinna? more or less deeply pinnathid into pauci-spinescent-crenate and Bpines- 

 cent-tipped erect-patent subfalcato-ovate or subfalcato-oblong-ovate lobes, 

 superior pinnte coarsely spineseent-crenato-serrate, lowest pinna largest and 

 attaining 28 cm long, 7 cm broad when well developed: veins erect-patent, 

 often more or less curved, pinnate : veinlets free, loose, erect-patent, simple or
