lower side, deeply pinnatilid, the lobes lanceolate. Texture moderately firm; 

 both sm'face sfinely pubescent; main veins distinct to the margin; areolae 

 with copious free veinlets. Sori 2-serial, approximate to the main veins ;

Rhizome short, ascending. Stipes 40—60 c.M. long, stramineous or brown, 

 the base clothed with lanceolate, arcuate scales + V2 m.M. long, the rest 

 naked like the rachis Fronds 30—50 c.M. long, ovate, pinnate, the barren 

 ones the largest. Terminal pinna ± 25 c.M. long, + 7 c.M. broad, acumi- 

 nate, entire or subrepand ; below this 3 — 5 lateral pinnae on each side, 

 which are sessile, erecto-patent, straight or subarcuate, lanceolate, IB — 20 

 c.M. long; fertile pinnae smallei', + 10 c.M. long, ± 2 c.M. broad, obscurely 

 crenate, the lowest stjlked. Texture subcoriaceous; surfaces naked; main 

 veins almost reaching the margin; areolae irregular, with included, free vein- 

 lets. Sori large, in 2 rows between the main veins, almost covering the 

 entire lamina; indusium persistent. — A form from Borneo, cultivated in 

 the Buitenzorg gardens has the pinnae of both barren and fertile fronds + 2 

 X as broad as in the philippine plant (forma latipinna).
