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, 

 scarcelj' pubescent. Pinnæ opposite, 15 cm long, 2'/-' cm broad, coriaceous, glabrous 

 above (the sparsely setose costa excepted), margins, costæ and costulæ beneath 

 rather densely soft-hairy by very long, tliin, 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, W'hich 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.).

(Ecuador, Spruce nr. 5300, Kew! RB; nr. 5299 and 5301 quoted by 

 Hooker I refer to D. pachyrachis).
