A Brazilian representative of the Andine D. refulgens and together with that 

 species dilYerent from all other species of the subgenus by the pinnæ being incised 

 scarcely more than halfway to the costa. From D. refulgens it differs 1) by the 

 dark-green leaf, which is 20 — 25 cm broad; pinnæ 2'/3— 3 cm broad, 2) pinnæ from 

 a truncate base oblong-linear with parallel edges suddenly narrowed into a short, 

 acute apex; segments close, 4 mm broad, truncate and often emarginate at the 

 apex; veins 7 — 9, the lower 2—4 running to Ihe sinus, all reaching the margin, or 

 often the lower-most pair do not reach the sinus but end in the leaf-tissue below 

 the sinus, 3) rachis and costæ beneath sparingly scaly; scales small, dark reddish- 

 brown, mostly ovale with a short apex and shortly toothed margins; cell-walls
