Rhizome wide-creeping; scales linear-lanceolate, the base peltate, the 

 edge entire. Stipes distant, 10 — 50 c.M. long, erect firm. Fronds 20 — 60 

 c.M. long, 15 — 40 c.M. broad, deltoid to broad-lanceolate, 5 — 5-pinuatifid ; 

 main rachis hardly at all winged. Pinnulae of the lowest pinnae lanceolate, 

 1 — 4 c.M. long, 2 — 10 m.M. broad. Segments narrow, sharply toothed, 

 mucronate. Texture coriaceous; veins not immersed, 1 — 3 carried into each 

 tooth, with spurious veins between the true ones. Sori small, with the 

 sharp mucro of the tooth extending beyond; indusium half-cupshaped, semi- 

 orbicular, + as long as broad. — Scarcely different from D. denticulata.

Rhizome stout, creeping, densely fibrillose. Stipes 10 — 15 c.M. long, 

 stout, erect. Fronds 30 — 65 c.M. long, 15 — 45 c.M. broad, deltoid, 5-pinna-

 pinnae lanceolate-acuminate, l^j^ — 10 c.M. long, 2 — 3 c.M. broad, cut down 

 throughout within a short dislance of the costulae with broadly toolhed, 

 linear-oblong segments. Texture subcoriaceous. Sori 1 to each tooth, the 

 blunt teeth slightly projecting beyond them; indusium half-cupshaped, as 

 long as broad, not reaching the margin.
