Mindanao Isl., Prov. Davao, Todaya, ou the truuks of 

 trees, 1100 m. s. m. (Copeland no. 1286). 



Xear N. rufescens, from which it is distinguished by its 

 sleuderness better than by the usually absolutely glabrous 

 pinnae.

Luzon Isl, Prov. Bataan, Mt. Mariveles, 1000 m. s. m. 

 (Copeland no. 1381, Merrill no. 3238, Whitford n. 248). 



Because of the "Fructificaciones en dos lineas paralelas, 

 y aproximadas a la costilla de la fronde", Blanco ascribed this 

 fern to Blechnum. His description is so vague I would not 

 think of displacing another name for his, but as this species 

 is new to science, and agrees with the few details in Blanco's 

 description, and avo know that he had plants from Mt. Mari- 

 veles, I think it better to get rid of a lost name by rehabili- 

 tating his than to introduce a new one.
