Stipes approximate, + 8 — 20 cm. long, those of the fertile fronds the 

 longest, clothed with rather deciduous, membranaceous scales. Barren 

 fronds oblanceolate, ± 20 cm. long, + S'/j cm. broad near the rounded 

 apes, narrowed gradually into the stipe. Texture coriaceous; the edge 

 cartilagineous. Fertile fronds linear-eUipticalj + 16 cm. long, + a'/^cm. 

 broad, abruptly shortly decurrent. — Intermediate between E. decurrens

 Rhizome clothed with long, brown, subulate, ciUate scales. Stipes

 quite to the base. Barren fronds up to + 20 cm. long, + B'/i cm. 

 broad, obovate, obtuse, the margin bounded by a pale, thin, membran- 

 aceous line. Texture corky-coriaceous ; colour ochraceous ; upper surface 

 smooth, lower covered with numerous scattered, hairy dots; costa flat- 

 tened; veins hidden, spreading, reaching the margin. Fertile fronds 

 similar to the barren ones but smaller, and the marginal membrane
