FOSSIL LEAVES OF PALM TREES.

of a warm temperature, seems to indicate that 
the climate of Europe during the Tertiary period, 
tvas warmer than it is at present. 
Fossil Palm leaves. 
We have seven known localities of fossil Palm 
leaves, in the Tertiary strata of France, Switzer- 
land, and the Tyrol ; and among them at least 
three species, of flabelliform leaves, all differing 
aot only from that of the Chamcerops liuniilis, the 
only native palm of the South of Europe, but also 
Irom every known living species.* These leaves 
are too well preserved to have endured transport 
l^y water from a distant region, and must appa- 
I’ently be referred to extinct species, which, in 
the Tertiary period, were indigenous in Europe. 
No pinnated Palm leaf has yet been found in 
the Tertiary Strata, although the number of these 
loi’ms among existing palms, is more than double 
that of the flabelliform leaves. i 
* The leaf represented in PI. 64. tig. 1. is that of a fiabelli- 
fortn Palm (Palmacites Lanianonis), from the Gypsum of Aix in 
E'ovence; similar leaves have been found in three other parts of 
^ ranee, near Amiens, Mans, and Angers, all in strata of the 
tertiary epoch. Another species (Palmacites Parisiensis) has 
aen found in the Calcaire Grossier, near Versailles {Cuvier and 
^''Ongniart, Geognosie des Environs de Paris, PI. 8, fig. 1. E.) 
■'t third species of Palm leaf (Palmacites flabellatus) occurs in 
'^t'e Molasse of Switzerland, near Lausanne, and in the Lignite 
'rf Hoering, in Tyrol. See PI. 1. figs. 13. 66. 
t The Date, Cocoa-nut Palm, and Arena are familiar exam- 
ples of Palms having pinnated leaves. .See PI. 1 . figs. 67. 68.
