(62) P. albido-squamatum Blume. Rhizome stout, wide-creeping, 

 clothed with reddish or gray-brown palese which are ovate at the base and 

 long-subulate; stipe 15 to 40 cm. high, erect, polished; frond 30 to 60 

 cm. high, about 30 cm. broad, pinnate; pinnae erecto-patent, linear or 

 lanceolate, very acuminate, entire or nearly so, coriaceous, glabrous, the 

 lower stalked, the upper sessile; main veins visible but not conspicuous, 

 veinlets ending under submarginal lime-spots; sori in single rows, usually 

 nearer the midrib than the margin. Philippine specimens are mostly 

 narrower than the type, belonging in P. varians Blume, which is not a 

 distinct species.
