SUPPLEMENTARY NOTE ON LOCALIZED FLORAS. 
Herr Gothan in one of the German scientific journals, pre- 
sents evidence of dry- and of moist-climate areas in Europe dur- 
ing the Carboniferous time. He eliminates from consideration 
the cosmopolitan species of the Coal flora, which are very num- 
erous, and turns his attention to certain characteristic species of 
local distribution ; he thus establishes the range of a series of 
coal basins in a region that had a moist climate, ranging from 
Great Britain to Belgium, the Lower Rhine, and thence to Upper 
Silesia. To the south of this range of coal basins there were 
basins, as those in the valleys of the Saar and Zwickau and in 
the mountains of Saxony and Bohemia, which had a dry climate, 
as is shown in the floras of their coal basins. 
One of the plants mentioned as indicating a wet climate is 
the filicoid genus Lonchopteris, which differs from Alethopteris 
in having a reticulate in place of a forked venation in the leaves ; 
while on the other hand one which marks a dry climate is the 
net- veined Neuropteroid form Linopteris ; he mentions three other 
forms that are especially characteristic of a dry climate 
A parallel condition to this is that of the flora in the group of 
strata that underlies the Lower Carboniferous limestone in south- 
ern New Brunswick. At Perry, in Maine, it has a flora which 
has been pronounced Upper Devonian by Sir William Dawson 
and Mr. David White, in the Kenebecasis valley the flora is 
that of the “Lower coal measures” of Sir Wm. Dawson, which 
^Messrs. Ells and Fletcher found to be in Upper Devonian rocks. 
But on the shores of the Bay of Fundy the same formation 
contains abundant Catamites, and the genus Neuropteris, 
showing the existence of moist conditions of climate that encour- 
aged the growth of water-loving plants. On the opposite slope 
of the ridge in the Kenebecasis valley, ten miles away, flour- 
ished Lepidodendraceae in great numbers, with the fern-like 
Aneimites, while the Equisetaceae are rare and Neuropteris 
fern-like forms wanting.
