series, of »new species», evidently without having knowledge 
of species from other regions with which the proposed new 
ones should have been compared. Very few of PHILIPPI's 
new species will appear to be valid ones, but unfortunately 
it is rather impossible to decide with certainty from his 
descriptions alone, what his »species» may be. 
Examining more closely the specimens collected by Dr. 
SKOTTSBERG I quickly found, that not a few new observations 
could be gained for the right understanding of several species, 
and therefore I undertook a critical examination of the whole 
material with extent use of all the literature, to which I had 
access, and, continually and minutely comparing the specimens 
with others of the same species from different regions, as 
well as with related species. My results are laid down in 
this small paper, wherein only such species are dealt with, 
for which I have found new characters, or which, as I think, 
were misunderstood by some authors. 
Besides the new species Polypodium patagonicum I here 
describe two more, which, however, were known previously 
but wrongly identified with old species, viz. the new Fuegian 
Hymenophyllum, H. Skottsbergii, a remarkable near ally of 
the tropical H. abruptum, and the curious Blechnum longi- 
cauda from Juan Fernandez, which was detected by Jonow 
and identified by him with the Malesian Asplenium longissi- 
mum Bl. 
No new species is added to the flora of Fuegia or Southern 
Chile, but not a few to the flora of Juan Fernandez and the 
Falkland Islands. JoHow considered! 45 species as indigenous 
in Juan Fernandez. I fear that this number must be 
reduced, as some of the species enumerated seem to be forms 
of others also found in the islands. Dr. SKOTTSBERG has 
detected three species new to the islands, viz. 
Cystopteris fragilis (L.) Bernh. 
var. canariensis (Willd.) Milde from Masafuera 
Hymenophyllum peltatum (Poir.) Desv. from Masafuera. 
Serpyllopsis caespitosa (Gaud.) C. Chr. from both Masatierra 
and Masafuera. 
To these should be added Hymenophyllum tunbridgense (L.) 
Sm., Masafuera, which species JoHow mentioned as doubtful
