ON THE TERTIARY FLORA OF THE ARCTIC REGION, 83 
in Schosnitz; it might be figured on account of the variability to which 
the form of the willow-leaf is subject, but could hardly be made a dis- 
tinct species. 
c. A willow-leaf, the lower and visible surface of which is covered 
with numerous, thin, longitudinal strize, which conceal the veins, but 
are in their distribution quite independent of them; these strie may, 
in my opinion, be caused by hairs, in which case the leaf would belong 
toa new species, a hairy willow-leaf in a fossil condition having as yet 
not been met with.—Salix pilosula, Geepp. 
d, e, f, g, h. Alnus pseudoglutinosa, Goepp., three imperfect speci- 
mens, but two of them with the obtuse point of two isolated female 
catkins, which may perhaps belong to them. 
i. Caulinia levis, Gœpp., described by me from the Miocene lignite 
formation at Striese in Silesia,* belongs perhaps to Phragmites 
ingensis, which since then I have found undoubtedly near Griin- 
berg in Silesia, also in Miocene. From the same stratum as No. 2 
and in the same situation, but according to the schedule close to a so- 
called “ coal-conflagration,” two specimens of red-burnt clay, one of 
them with a leaf of Taxodium dubium, the other, unfortunately only 
partially preserved, but still with an impression deserving to be figured, 
similar to an evergreen Oak,—a genus to which we have been com- 
pelled to refer, from want of flowers or fruit, so many a leaf probably 
belonging to a very different source. Taxodium dubium, very close 
to the T. distichum of the existing flora, belongs like Sequoia Langs- 
dorfii to the most widely diffused plants of the whole Miocene forma- 
tion, being met with in Vancouver Island, Bellingham Bay in the 
Washington territory, probably also in Kamtebatka (see above), in 
eastern Prussia, Schosnitz in Silesia, at Bilin in Bohemia, Parschlug 
in Styria, Seesen near Beyreuth, on the Hohen Rhonen, Schangnan, 
Eriz im Sandstein von Rallingen, Lausanne in Switzerland, Oningen, in 
Baden, in the Arno valley and Sinigaglia in Italy, and in the Kirgise 
steppe. :
