D. dasyphylla is closely related to D. pilosa var. pubescens and I have been 
inclined to consider it the same plant; still it is much more hairy, the lamina 
upwards suddenly narrowed into a pinnatifid apex and with 6—8 pairs of opposite 
or subopposite, sessile or very short-stalked pinne, about 8 em long by 2!/,—2!/» 
em wide, the lower ones not reduced but narrowed towards their base, all cut 
about halfway down into close, broad subacute segments. Veins 6—7 to a side, 
simple. Sori short, often nearly round, the sporangia setose. Rachis, coste and 
veins of both sides with many long, soft, pluricellular hairs.

Type from Brazil, Rio, RApp: (not seen). The following specimens seen are 
all from the mountains of Rio and are very uniform. MosÉw nr. 2656 (H, Rg, S);

In colour, cutting and shape of pinnz very similar to D. monosora of the 
subgenus Goniopleris and also resembling D. alsophilacea of the subgenus Clenitis, 
still very different by the oblong to linear sori and the setose sporangia. The 
creeping rhizome is naked and the whole leaf practically glabrous, only the costze 
and costule are finely downy beneath. Lower pinnz with a short, cuneate, entire 
base, acuminate, at both sides equally incised about */; of the way down to the 
midrib into broad, obtuse, subfalcate segments; veins about 10 to a side, the lower 
two running to the sinus. 
Subgenus 9. Goniopteris (Presl) C. Chr. 
Biolog. Arbejder tilegnede Eug. Warming pag. 83. 1911. 
A large subgenus including about sixty good species and not closely allied to 
other Dryopterides. Its best and most constant character is the presence of unicellu- 
lar, forked or stellate hairs. Such hairs are to be found always on the scales 
of the rhizome and lower part of the stipe and in most species they also cover 
the rachis, especially upwards and above, and the coste beneath. In some species 
(D. nephrodioides and ils relatives) the rachis is very densely but very shortly pul- 
verulent by stellate hairs, in others (D. sclerophylla, D. asterothrix, D. reptans and 
others) the surfaces (veins and leaf-tissue) bear minute hairs with horizontal bran- 
ches. The stellate hairs are, as far as I have found, never sessile but consist of a 
short stalk, which bears at the point 2—6 branches. “The shape of the branches
