 furcatis, fere traiisvorsis; soris liiioarihiis, hoc costam nee niar- 

 ginem attingeiitibus. Sunt etiain fVondes plantaruni infantum '

Mindanao Isl., Prov. Davao, Mungalaion, on tbe trunks 

 of trees, in a forest near the sea (Copeland no. 664). 



This fern differs from A. vittaefornte Cav. in the thinner 

 texture, many forked veins and chaffy stipe; and ivom A. sco- 

 lopendrioides J. 8m. in the almost horizontal veins and toothed 

 margin. Wakbuiki collected A. riltaeforme near Davao. And 

 a fern collected by Dk Voue and Hoover no. 329, fi'om Mt. Apo, 

 probably at about 1800 m, is nearer to A. scolopeiidrioides but 

 the indusium leaves no prominent line wiien it dehisces: this 

 line is very evident on specimens collected by Merrill in 

 Mindoro.
