terminating in the leaf-tissue in a clavate apex, not reaching the margin and, in 
some species, irregularly anastomosing. In lack of simple hairs and in the structure 
of the scales Stigmatopteris resembles Eudryopteris, but the venation and the exindusiate 
sori are quite different. I am fully convinced that Stigmatopteris is a very natural 
genus (perhaps even not a member of the Dryopterideae), but as the same can be 
said of several other subgenera of Dryopteris dealt with in this paper it is best 
for the sake of uniformity of treatment to place Stigmatopteris here among the 
other subgenera. 
Since the publication of my paper on Stigmatopteris I have seen some other 
species, which belong here. It is very interesting to note that some of these 
species are indusiate, but the indusia are not reniform as in Dryopteris but 
peltate, large and circular, fixed at the centre, as a rule coriaceous and glabrous, 
the edges often upcurved. Species with such indusia have commonly been referred 
to Polystichum, but there exists no species of true Polystichum haying a similar 
habit. In general habit the species here in question do not differ from Stigmatopteris 
rotundata and allied species, and as to all other characters they fully agree, infer 
alia also in the variable venation and in the presence of immersed glands. FEE 
has named provisionally a plant from Guiana Peltochlaena nephrodiiformis, which 
no doubt belongs here. I can not say definitely what his species may be, but I 
use here his name Peltochlaena for a section of Stigmatopteris including those 
species having peltate indusia. It must be remembered that the very large indusia 
soon fall, and a fertile leaf with all indusia fallen could as well be referred to 
Eustigmatopteris. 
The genus (subgenus) thus can be divided into two groups: 
1. Eustigmatopteris. Sori exindusiate. Leaves as a rule thin. 
2. Peltochlaena (Fée). Sori furnished with large, circular, peltate indusia. 
Leaves generally papyraceous to coriaceous. 
In my former paper I have exclusively dealt with the species of the former 
group and I have there mentioned and illustrated 12 species. Since then I have exam- 
ined the type-specimens of some species described by Hooker and Baker, and the 
number of species known to me is now 17, which are all enumerated below and 
arranged in a key. For descriplions, synonymy and distribution of the 12 species 
I refer to my former paper. 
Key. 
1. Sori exindusiate. Lamina of most species herbaceous or membranous. 
Eustigmatopteris. 
2. Pinnz nearly entire, serrated or lobed not more than '/» of the way 
down to the midrib, seldom a little more. 
3. Sori round, not confluent; veins free. 
4. Only the uppermost pinnze with a shortly decurrent base.
