sessilibus, horizontalibus, lanceolatis, breviter acuniinatis. Laciniis 20 — 25 jugis, ala 

 1 mm. lata connectis, subfalcatis, acutis vel subobtusis, versus apicem leviler creiiato- 

 dentatis, basalibus aequalibus. Venis indivisis, 9 — 10 jugis. Soris margini magis 

 quam costulae approximatis, parvis. Indusiis parvis, cilialis, mox deciduis. Spo- 

 rangiis glabris. 



Intermediate between D. concinna and D. oligocarpa. It resembles the former 

 in habit and in the very short pubescence of rhachis, bul the sporangia are gla- 

 brous and besides the very short hairs found throughout on the lamina, the veins 

 on the upperside are furnished with solitary, longer and more rigid hairs. From 

 D. oligocarpa it differs by the short pubescence of the rachis without long hairs, by 

 the length of the lamina and by the distant pinnæ. It is no doubt this species 

 Mettenius has named Aspidium socium on the labels to some specimens in HB 

 from Venezuela: Caracas, Moritz n. 36, Karsten & Moritz; the same form also 

 from Trinidad, Fendler (HB). Unfortunately I had returned the specimens so- 

 named, as I received D columbiana from Dr. Chiust.

Rhizome wanting. Very near Ü. columbiana, but texture firmer and without 

 the long setæ on the veins above; segments sub-patent, obtuse, with a considerable 

 space between them. Sori supramedial, exindusiate; sporangia glabrous.
