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. PnEsr; B). 
2. var. Schiffneri n. var. (D. Schiffneri 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. Coste 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. EccEns nr. 15319 (B!). 
A weakly characterized species of the same general aspect as D. nephrodioides, 
D. lugubris and allied species. From JD. nephrodioides it differs by the absence of 
stellate hairs on the leaf-tissue and by the presence of large, brown scales on the 
erect rhizome and the basal part of the stems. From JD. 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 coste 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 dcm long with 20— 25 pairs of pinnz, 15 
cm long by 2 cm broad. Rachis densely pulverulent by short stellate hairs and 
upwards furnished with several long, white hairs. Upper surface glabrous except 
the strigose costz and ciliate margins, under-surface throughout finely pubescent 
by simple hairs, the costze 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 sete. — From JD. gemmulifera it differs by its denser pubescence of stellate 
hairs, absence of gemmsze 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.,
