 10 — 20 c.M. long, 1 — 2 c.M. broad,, the fertile region contracted, the point 

 acute, the base narrowed very gradually. Texture coriaceous, thick; upper 

 surface naked, lower clothed with thin tomentum; veins hidden. Sori occu- 

 pying the upper half of the frond, minute, immersed in a pale-brown tomen-

Rhizome creeping; scales roundish or oblong, rarely acute, peltate, ad-

 young, ± entire. Stipes 3 — 7 c.M. long, deciduously tomentose with adpres- 

 sed stellate hairs. Fronds uniform, 20 — 60 c.M. long, 1 — 3 c.M. broad, ligu- 

 late or linear, the apex bluntish or subacute, the edge entire, the base nar- 

 rowed gradually. Texture coriaceous ; upper surface naked or nearly so, lower 

 tomentose, the stellate hairs greyish or brownish, often white when young, 

 crowded but adpressed ; costa conspicuous ; veins hidden. Sori small, close, 

 numerous, crateriform, occupying the upper Vs—Vs "^ the frond, slightly 

 immersed in shallow cavities, which are not or obscurely prominent on the
