 subbullate, lanceolate, acuminate and a few large, linear-subulate, ferrugineous 

 scales, the two kinds of hairs separated by long, subflhform-subulate, 

 crisped, brown scales. Pinnulae 4'/2— 5',j cm. long, 1 — I'/a cm. broad 

 at the base, shortly acuminate, cut down nearly or quite the costa, 

 pinnate at the base. Segments subfalcate, obtuse or very minutely 

 apiculate, crenate, 2% mm. broad, the lower free, adnate (always ?j. 

 Texture coriaceous; costae (tertiary rachises) hairy above, scaly beneath, 

 the lower scales rather dense, linear-subulate, passing gradually into the 

 very small, bullate higher ones; costulae (at least the lower; bullate-

 Sori subcostular, occupying the lower veins, hidden among the scales;
