Detailed description. — Rhizome oblique, suberect. Stipes ± 4 — 5, sub- 

 tufted, naked, rufo-stramineous, to ± 45 c.M. long, provided on each side 

 with 8 — 10 rudimentary, distant, obtuse auricles, the base clothed with long, 

 lanceolate-subulate, hair-pointed, brown scales. Fronds ovate-acuminate, 60 

 c.M. long or longer. Pinnae alternate, erecto-patent, numerous, sessile or 

 short-stalked, + 14 c.M. long or longer, 1—1 V2 c.M. broad, cut to Vs^way 

 down to the costa, the base truncate on the upper, semicordate on the lower 

 side, the apex caudate-acuminate; terminal pinna often very elongated. Lobes 

 decumbent, + 5 m.M. long, subobtuse. Texture subcoriaceous ; surfaces naked 

 like the rachis; colour brownish-green; costae distinct, pale; veins ± 5 — 8 

 on each side, only the lowest anastomosing. Sori minute, medial, + 5 on

Near D. basilaris, C. Chr. Rhizome thick, oblique, black-brown. Stipes 

 tufted, 2 — 5 c.M. long, rufo-stramineous, whether or not clothed with some 

 scattered, brown scales. Fronds oblong, 16 — 24 c.M. long, 4 — 6 c.M. broad, 

 caudate. Pinnae ± 12 on each side, ± 5 c.M. long, + '/2 c.M. broad, sessile, 

 the base nearly hastate or auriculate on both sides, the anterior auricle the 

 largest, the edge cut hardly V^-way down to the costa into truncate lobes; 

 lower pinnae gradually reduced into mere, obtuse auricles 5 — 5 m.M. each 

 way. Surfaces naked; rachis stramineous, sparingly furfuraceous ; main veins 

 sparingly pinnate in the lobes, the lowest veins anastomosing irregularly. Sori
