Rhizome creeping, the scales dense, long, linear-lanceolate, brown. Stipes 

 2'/j — 15 c.M. long, those of the fertile fronds the longest. Barren fronds 

 15 — 40 c.M. long, 4—8 c.M. broad, the apex bluntly rounded, the margin 

 cartilagineous or ± pellucid, the lower part narrowed gradually into the 

 stipe. Texture coriaceous; surfaces naked or the under side sparingly and 

 minutely scaly, the edge more or less fringed with minute, ovat6-lanceolate,
