narrowly lanceolate, lobed or pinnatifid, the lobes ovate-lanceolate, acute, 

 coarsely toothed. Surfaces nearly naked ; veins blackish. Indusia peltate. 

 — A dupUcate of Elmer's No. 117-12, from Mount Apo, has the main 

 rachis sparingly scaly, roughish, the pinnulae about 15 — 20 cm. long, 

 2-5 cm. broad, the higher pinnulae connected, sinuate-lobate, the lower 

 pinnatifid, the lobes blunt, entire to lobate-dentate, the veins forming 

 1 — 2 rows of areolae on each side of the costae and costulae (except in 

 the higher pinnae and lobes, where they are anastomosing less copiously), 

 for the rest free towards the margin, the sori in 1 row (or more 

 commonly 2 irregular rows) on each side of the costulae, or scattered in 

 the larger lobes, the indusia reniform.
