Rhizome creeping, the scales linear, pale-brown. Fronds sessile, close, 

 ligulate-linear, obtuse, 2 '/j — 5 cm. long, 2 '/j —4 mm. broad, narrowed 

 gradually to the base. Texture coriaceous; costa distinct beneath from 

 the base to the apex, slightly sulcate above; veins oblique, simple, sub- 

 immersed, hardly produced beyond the receptacle in the fertile region, 

 the lamina beyond the sori rather thin, much produced beyond the costal 

 parenchyma which is + half as broad as the lamina.

Rhizome ascending, the scales yellow-brown or brown, linear-subulate 

 or lanceolate, hidden among the roots and fronds. Fronds approximate, 

 numerous on the longest rhizomes, linear, 2 — 15 cm. long, 2 — 4 mm. 

 broad, sometimes slightly dilated and often nearly as thick as broad in 

 the fertile region, simple or occasionally forked, the apex blunt or 

 rounded, the lower part narrowed gradually to the base or a short stipe. 

 Texture coriaceous; midrib rather distinct beneath but lost in the fertile 

 region, somewhat grooved above; veins free, oblique, forked. Sori 

 confined to the upper '/j — '/^ of the frond ; the lamina beyond the sori
