1. Miocene Flora of the Polar Regions.—We have heard much 
of late of the extensive collections of fossil plants from various 
pre of the arctic regions, which have recently been studied by 
of. Heer. We have not seen his Flore Fossile de Régions Polaires, 
but an article in the. Bibliothéque Universelle, translated for 
" i 
the Annals and Magazine of Natural History, gives an interesting 
_ Summary of the striking results 
The arctic fossil flora counts 162 known species, of which 18 are 
Cryptogamic, 9 of them Ferns of large size. There are 31 Co- 
nifer, 14 Monocotyledons, and 99 Dicotyledons a al Seventy- 
8 
Iceland, and Spitzbergen, no less than of Arctic America, mostly re- 
semble existing North American species. There is a Spruce very 
ern trees, Seguota or Redwood, now represented in California only, 
in two species, had four species in the Miocene po , three of 
which occur at the same level in Central Europe. One of these 
t 
the S. gigantea. A third, from Greenland, is intermediate between 
these two. The bearing of facts like Sip is obvious, as also that 
cies being from Japan. The Cypress family is represented b 
Taxodium and the allied Glyptrostrobus, also by Thujopris, a 
H wer 
all three approaching certain United States species. There were 
then, in these now icy regions, forests of various deciduous or ever- 
green broad-leaved trees, as we oniferse of various forms, 
“vines and ivy entwined these with their branches, and beneath 
their shade grew numerous shrubs and elegant erns. A. Ge.
