1. f. typica. 



Rachis without buds; veins 9 — 10-jugafe, the lower 4 — 5 connivent to sinus; 

 only the anterior basal vein soriferous. Segments generally more acute than in 

 the following form. 



Hereto the type-specimen and the following: Sao Paulo: Rais da Serra, 

 Wacket nr. 224 (R) — Ins. S. Sebastian, Casaretta nr. 130 (Hb. Presl; B). 



2. var. Schiffneri n. var. (U. Schijfneri mihi in Herb. plur.). 



Rachis often gemmiferous. Veins 13 — 15-jugate; the lower 3 — 4 connivent to 

 sinus, about all soriferous. Segments often with rounded apices. Costæ less scaly. 

 I had described this variety as a new species, but I now consider it the fully 

 developed form of D. monosora.

Type from Ecuador, El Recreo, leg. Eggers nr. 15319 (B!). 



A weakly characterized species of the same general aspect as I), nephrodioides, 

 D. lugubris and allied species. From D. nephrodioides it differs by the absence of 

 stellate hairs on the leaf-tissue and by the presence of larpe, brown scales on the 

 erect rhizome and the basal part of the stems. From Ü. lugubris, which it resem- 

 bles closely, it differs by its erect rhizome, thinner texture, fewer veins and, espe- 

 cially, by the absence of scales on rachis and costæ beneath. A good character 

 is also the shape of the stellate hairs of rachis; they bear on a stalk 3—4 branches, 

 which are again forked. Lamina 7 8 dem long wilh 20- 25 pairs of pinnae, 15 

 cm long by 2 cm broad. Rachis densely pulverulent by short stellate hairs and 

 upwards furnished wilh several long, white hairs. Upper surface glabrous except 

 the strigose costæ and ciliafe margins, under-surface throughout finely pubescent 

 by simple hairs, the costæ besides densely stellato-pulverulent. Veins 10 — 12-jugate, 

 simple, the 2 — 3 lower ones connivent to sinus. Sori medial, the indusium sub- 

 persistent, setose by simple hairs. Sporangia glabrous or rarely furnished with a 

 few setæ. — From D. gemmulifera it differs by its denser pubescence of stellate 

 hairs, absence of gemmæ and by its lamina being shortly narrowed upwards, not 

 gradually tapering to the point. 



D. nutans Christ from Costa Rica is this species; the specimens are larger 

 than the original one, dark-green and less pubescent beneath. N. tetragonnm Sod.,
