Near D. dives, Kze, but the fronds mostly longer, + 30 — 45 c.M. long, 

 4 — 20 c.M. broad, lanceolate or subtriangular-lanceolate, deeply pinnatifid in 

 the upper, but pinnate in the lower half. Segments linear, bluntish or 

 acute, toothed or serrate, the higher ones conflent, the central ones confluent 

 or contiguous and some of the lowest pairs quite free and cordate or dis- 

 tinctly auricled, or even hastate at the base. Texture more or less coriaceous ; 

 surfaces naked. Sori oblong, straight or recurved, ± distant, in 1 — 2 rows 

 on each side, the inner rows not rarely at some distance from the midrib.

Sori oblong or linear-oblong, in 1 row on each side, parallel and nearly 

 close to the costa, immersed in cavities occupying the costal areolae. Indusium 

 of the same shape as the sorus, attached at the outer side, covering the 

 cavity like a lid, opening inwardly. 



R hiz o m e c rocti Stipes not articulate to the rhizome. Fronds pinnate or 

 2-pinnatifid; veins anastomosing to form 1 or more rows of areolae between 

 the midrib and the edge. Hk. Bk., Syn: Fil., tab. IV, fig. 36; Diels, in Engl.
