Type from Columbia, leg. Lehmann n. 557 (HB!). — Peru: Lima, Gaudi- 

 chaud (HB). 



In his excellent description the author says: "(pinnis) infimi paris auriculi- 

 I'ormibus"; he has overlooked that below IJiis pair two other pair of very small, 

 nearly glanduliform, distant pinnæ are I'ound. The sj)ecimcn from Peru agrees 

 very well with the original one, but it bears 8 pairs of auriculil'orm pinnæ. The 

 species resembles in shape of lamina a member of the group of I). Sprenyelii, but 

 in size and number of veins (8 — 9) it shows alTmily with D. Lindigii, Ü. oliyocarpa 

 and other species of this group.

In habit, size and texture this species comes very near to Ü. oligocarpa, but 

 with the exception of the costæ, which are hairy above, it is nearly quite glabrous 

 having onlj' a few deciduous hairs on the rachis, costæ and veins. It has several 

 (3 — 4) pairs of gradually reduced pinnæ, the lowermost being auriculiform, often 

 trilobed. 



Rhizome of the original specimen oblique, ca. 1 dem. long by 1 cm. thick, 

 covered with numerous bases of stipes of old leaves and at the apex with a few 

 brown, thin scales; the leaves fasciculated at its top. Stems slender, stramineous, 

 towards their base blackish, glabrous or very sparingly pubescent, with a few 

 thin scales at base. Pinnæ opposite, the lower non-reduced reflexed, articulated to 

 the rachis. Basal segments not enlarged. Veins 4 — 6 to a side; sori medial or a 

 little above the middle of the vein; indusium not seen. 



The specimen from Costa Rica referred to was determined by Christ as 

 0. cdiicaensis, which is a widely dillerent species; it differs in habit very much 

 from the normal form, having the outer half of the pinnæ pendent and their 

 anterior segments reflexed and overlapping the posterior ones, in about the same 

 manner as in Lindsaya dubia Spr., but in the essential characters I see no difference. 

 A single leaf of Lindig n. 321 shows partly the same peculiarity, and I have no 

 doubt that my determination is the right one.
