Stipes + 30 c.M. long, clothed with long, spreading, brown, lanceolate- 

 subulate scales, scabrous when they fall. Fronds ± 30 c.M. long, 20—25 

 c.M. broad, lanceolate-deltoid. Lowest pinnae stalked, + 12 '/j c.M. long, 

 IS — 20 m.M. broad, cut down to a narrowly winged rachis into close, linear- 

 oblong, entire lobes. Texture coriaceous ; rachis like the stipe ; under surface 

 thinly pubescent and glandular; veins 7 — 8 on a side, the lowest sometimes 

 joining. Sori nearer the midrib than the edge.

Rhizome scaly; the scales brown, linear-lanceolate, acuminate, ciliate. 

 Stipes subtufted, ± S — 10 c.M. long and like the rachis greyish or brownish, 

 densely short-hairy. Fronds linear-lanceolate, acuminate, pinnate, ± IS — 20 

 c.M. long, + 3 — 4 c.M. broad, with a pinnatifid apex and an elongate, 

 crenate point. Higher pinnae oblong, entire, sessile; following pinnae sub- 

 sessile; central pinnae close, short-stalked, erecto-patent, falcate, ± 1 c.M. 

 broad, the base truncate, auricled on the upper side, the edge pinnatifid ± 

 Ys on the way to the costa, but more deeply and nearly to the costa towards 

 the base, the apex oblong, blunt, entire or crenate; lower pinnae shorter, 

 deflexed. Lobes blunt, subentire. Texture semicoriaceous ; under surface 

 densely glandular and short-hairy; veins forked, or pinnate in the lobes. Sori 

 medial on the veins, in 1 row on each side of the coslulae ; indusium densely 

 hairy. — Fronds with the general aspect of D. pilosiuscula, C. Chr., but the 

 pinnae more deeply lobed and the upper surface naked.
