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

 tufted, naked, rufo-stramineous, to + 4S 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 



S short-stalked, ± 14 c.M. long or longer, 1 — 1\ c.M. broad, cut to '/s-^ay 



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



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



% decumbent, + 3 m.M. long, subobtuse. Texture subcoriaceous ; surfaces naked 



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

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

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

 caudate. Pinnae ± 12 on each side, + 3 c M. long, ± '/^ c.M. broad, sessile, 

 the base nearly hastate or aui-iculate on lith 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 lowesf veii s anastomosing irregularly. Sori
