This was founded on a fragment, the upper part of a leaf. but I have no 
doubt that it is a very distinct species allied to D. multiformis and that its proper 
position is here. 
Rachis stramineous, trisulcate above with light brown scales in the furrows, 
scarcely pubescent. Pinnz opposite, 15 cm long, 2'/ cm broad, coriaceous, glabrous 
above (the sparsely setose costa excepted), margins, coste and costule beneath 
rather densely soft-hairy by very long, thin, whitish, pluricellular, patent hairs and 
with several light-brown thin scales. Segments rather close, linear-falcate, obtuse, 
the basal ones reduced and auricled at the inner side. Veins simple, 15—17-jugate. 
Sori about medial, exindusiate.

The Andine forms of this most distinct species do not agree perfectly with 
the Brazilian type, still I can not make them a separate species. The differences 
are only small; perhaps the most constant is the presence of an auricle on the 
inner side of the lower basal prolongated segments, which overlaps the rachis 
above; in the Brazilian form this auricle is very small or absent. As to pubescence 
and glandulosity the Andine forms are somewhat variable. They have been 
described under several names, but I cannot see any clear difference between the 
forms, and I refer them all to a single variety: 
var. resinoso-foetida (Hook.).
