 to several, approximately scattered, lanceolate to lio ear-lanceolate, often 

 caudately prolonged above with an obtuse tip, narrowed gradually and 

 decurrent below, apparently petiolate, irregularly obscurely subrepand, 

 chartaceo-subcoriaceous, glabrous, 8-26 cm. long, l-2§ cm. broad ; midrib 

 slender, prominent on both sides ; main veins not distinct, not reached to 

 the margin ; veialets forming oval to narrow-oblong and angular areolae 

 including a simple or divaricately bifurcate, free venule with a minute 

 tubercle at the end ; petiole 1-4 J cm. long. Sori absent in the lower 

 portion of the frond, one -seriate on each side and arranged nearer the

This differs from the typical one by the thinner and much broader 

 frond, having a resemblance to Polypodium annuifrons Makino, from which 

 it is often hardly distinguishable in dried specimens, but the frond is 

 persistent and often long-tailed at the apex.

 ferruginous. Frond eUiptical to oblong ; pinnae 10-15 on each side ; the

 third of the frond.
