Texture rigidly coriaceous; surfaces naked; main veins (of the lobes) distinct

Rhizome stout, the scales ovate, short, adpressed, black or brown, peltate, 

 eroso-ciliate, with a suddenly narrowed, long, linear-subulate, often recurved, 

 fugacious apex. Cup-leaves bluntly lobed, + similar to those of D. quercifolia, 

 J. Sm. Fertile fronds 43—90 c.M. long, 15—33 c.M. broad, stipitate, cut down 

 nearly to the costa into erecto-patent, lanceolate to linear, entire lobes; 

 lower lobes decurrent so as to form a shorter or longer wing to the stipe. 

 Texture rigidly coriaceous; surfaces naked; main veins distinct to the edge; 

 areolae large, + quadrangular, divided into numerous finer ones. Sori small, 

 scattered irregularly.

Rhizome stout, creeping, the scales linear-lanceolate, narrow, ciliate, erecto- 

 patent, brown, with the base adpressed. Cup-leaves sessile, 15—30 c.M. long, 

 7 — 10 c.M. broad, the base sinuate, the edge deeply incised towards the costa 

 into blunt, oblong or linear lobes. Fertile fronds 60—120 c.M. long. 15 — 45 

 c.M. broad, pinnate, long-stalked, the stipe and rachis grey or brown, densely 

 clothed with a greyish tomentum consisting of deciduous, copiously ciliate, 

 peltate scales, at length naked, the stipe purveyed with 2 opposite rows of 

 few distant, large glands (rudimentary pinnae). Pinnae to a'/^ c.M. or more 

 apart, 4 — 10 m.M. broad, stalked or sessile, with a cuneate base, articulate 

 to the rachis, the edge entire, crenate or toothed, the apex acuminate. Tex-
