Many of the above are minute or obscure plants, and are 
closely allied to other European species with which they may 
have been confounded. We cannot therefore lay any stress on 
these individually as being absent from the continent of Europe 
so much of which is imperfectly explored, though it is probable 
that some of them are really confined to Britain. But there are 
a few — indicated by italics — which are in a very different 
category ; for they belong to genera which are altogether un- 
known in any other part of Europe, and their nearest allies are 
to be found in the tropics or in the southern hemisphere. The 
three non-European genera of mosses to which we refer all have 
their maximum of development in the Andes, while the three 
non-European Hepaticse appear to have their maximum in the 
temperate regions of the southern hemisphere. Mr. Mitten 
has kindly furnished me with the following particulars of the 
distribution of these genera : — 
Streptopogon is a comparatively small genus, with seven species in the 
Andes, one in the Himalayas, and three in the south temperate zone, besides 
our English species. 
Daltonia is a large genus of inconspicuous mosses, having seventeen 
species in the Andes, two in Brazil, two in Mexico, one in the Galapagos,
