AUSTRALIA AND EUROPE FORMERLY ONE CONTINENT. 21 
have found of them different leaves, fruit, and seed, and are 
in a position to make out even certain genera, such as BanJcsia 
(fig. 13), Dryanclra , Hakeci, Embothrium (fig\ 12), Gh'evillea (fig. 
10), Lomatia , Persoonia, Petrophyllum, &c. Thus it would 
•appear that the Proteacece now constituting the bulk of 
the New Holland vegetation played a similar part during a 
former geological epoch of Europe. Greater stress has, 
however, to be laid — because the character of New Holland 
and the Southern Hemisphere is more especially determined 
by them — upon the presence of the Santalacece } Antliobolece , 
and Monimicicece, particularly the genus Leptomeria, of which 
several species have been discovered in the Tyrol and in 
the lignite deposits of the lower Rhine. Closely related to 
these leafless shrubs is the Australian Cherry ( Exocarpus , 
fig. 9), which, strange to mention, is found amongst the 
fossils at Nadoboj (fig. 8). Nor must we omit to enumerate 
the genus Laurelia, which is peculiar to New Zealand and the 
mountains of Southern Chili. All these fragments make it 
evident that the flora of the Eocene period bore the character 
of the present Australian vegetation. But what are we to add 
about the Gonifercc , Cupuliferce, Gasuarinem, Araliacece, Lcgn- 
minosce, &c. ? Amongst the most common fossils of Sotzka 
and Haring are the branches of a coniferous plant which 
has its exact counterpart in the genus Araucaria ; and 
the latter, as it is well known, belongs exclusively to the 
Southern Hemisphere, New Holland and Norfolk Island pos- 
sessing five species. Podocarpus, Libocedrus , and Gallitris, 
may also be named as natives of the same hemisphere, and 
fragments of them are found in nearly all localities of the 
Eocene formation. Who does not know the Gasuarinece of our 
greenhouses, and that those leafless, equisetum-like trees 
are almost exclusively met with in New Holland ? They 
also seem to have been represented in pre-historic ages. 
It is also worthy of remark that amongst the numerous 
fossil-oaks of the Eocene period, there is one with the 
type peculiar to the Javanese ones of the existing vegeta- 
tion ; and that the dwarf Beeches of Tierra del Fuego, 
Chili, Van Diemen's Land, &c., of the present day (figs. 
2, 3, 4, 6, and 7) probably also existed formerly (figs. 1 
and 5). Many more instances could be cited, but we may 
content ourselves with casting a look upon the widely- 
diffused and polymorphous class of Leguminosce. As is well 
known, it is divided into several tribes, every one of which, 
preferring a certain climate, has selected this or that country 
as its principal dwelling-place. Amongst those with pea- 
flowers the Ealbergiece and Ccesalpinece are only met with in 
the tropics ; whilst the Mimoscce form a considerable portion of
