Rhizome wide-creeping, the extremity clothed with ovate-deltoid scales. 

 Stipes 20 — 50 c M. long, brownish, naked. Fronds 50 — 60 c.M. or more long 

 + 10 — 20 c.M. broad. Pinnae numerous, erecto-patent, 5 — 12 '/^ c.M. long, 

 + ^/j — 1 % c.fti broad, the edges cut '/4 — %-^^J down into + erecto-patent, 

 triangular, acute, entire or toothed lobes ; lower pinnae not or a little smaller 

 than the others. Texture coriaceous; veins 5 — 8 on each side of the main 

 veins, the 1 — 2 lowest ones anastomosing; rachis and surfaces naked. Sori 

 nearly terminal on the veins, at length confluent and forming a zigzag line

Rhizome stout, creeping. Stipes 25 — 30 c.M. long or longer, stout, brown- 

 ish, villose. Fronds 40 — 60 c.M. long, + 20 — 50 c.M. broad. Pinnae nu- 

 merous, + 1 — IV2 c.M. broad, cut + Vs-way down to the costa into sharp, 

 triangular, ± falcate lobes; lower pinnae dwarfed, distant. Texture rather 

 coriaceous; rachis and under surface villose, upper surface + short-pubescent; 

 main veins pinnate in the lobes ; veins 6 — 8 on each side. Sori in 1 row on each 

 side, ± close to the midribs or more numerous and then in pairs close to the 

 intermedial veins; sporangia setose. — Fronds with the aspect of D. cucullata, 

 Christ, but the lower pinnae conspicuously dwarfed only, not reduced into 

 mere auricles.
