On Fossil Plants from Washington Territory. 87 
as it seems so perfectly to agree with Oreodaphne Heerti, Gaud., 
that there is scarcely a doubt of the ey of the two spe- 
cies. But your leaf does not show mall holes or de- 
pressions marked in the axils of both the cater secondary 
nerves, You probably did not remark them. I beg you will 
again examine the specimen, and I feel confident that you will 
find there a small depression; if so, the identity of species is 
proved. The form and nervation of the leaves are truly pecu- 
- and already suffcient for identification. Oreodaphne Heerii, 
has been abundantly found in the upper Miocene and 
se Pliocene of Italy, but never till now on this side of the 
Alps. It much resembles Oreodaphne fetens of the Canary isl- 
a 
arched points. This is not marked in your drawing. These 
secondary nerves are somewhat too straight to belong to Quercus 
neriifolia.” 
“From these few species, we can ours see a near aan 
several 
Rhamnus Rossmaesleri or aoe a Smilax. easel paar there 
fore confirm our conclusion.” 
“ Another important deduction may be drawn from your 
plants, viz. that in the American tertiary flora, there are so 
Asiatic types which no longer belong to the American ware 
nent, namely Cinnamomum and Salisburi ; further an At- 
lantic type, the Oreodaphne. There is still an Oreodaphne in 
America; but the fossil species is related to O. feetens of the 
Canary Islands. A third conclusion taken also from the same 
_ plant is that fan-like Palm trees were growing at the same time 
in the same latitude with Sequoia and Yaxodium, and that there- 
fore we must admit of a warmer climate in North America at 
pres tepoch. And now from this fact that a flora of the same 
racter occurred at the tertiary epoch in Northern Europe and 
North America, it follows that both parts of the argh had a 
_ like warmer climate. It is a new and very important confirma.
