KEW HOLLAND IN EUROPE. 43 
several species, easily recognizable, have been discovered at Harin<? in 
the Tyrol, and in the lignite deposits of the lower Rhine. Closely re- 
lated 'to these leafless shrubs is the Australian Cherry {Exocarpus), 
which, strange to mention, is found amongst the fossils at Radoboj. 
Nor must we omit to enumerate the genus Laiirelia, which is peculiar 
to New Zealand and the mountains of southern Chili, and of which we 
possess highly characteristic fragments. All these specimens, imper- 
fect though they be, make it evident that the flora of the Eocene period 
bore the characteristic features of the present Australian vegetation. 
But what am I to add about the Coniferce, CnpnUfem, Casmr'mea, 
Jraliacecp, leffitmlnos^, etc. ? Amongst the most common fossils of 
Sotzka and Hjiring are the branches of a coniferous plant which has 
its exact counterpart in the genus Jraucaria ; and Jrancarla, as is well 
known, belongs exclusively to the Southern Hemisphere, New Holland 
and Norfolk Island possessing three [five] species. Pofhcarpns, Li- 
hocedrus, and Callltrls may also be named as natives of the same 
hemisphere, and fragments of them Jfre found in nearly all localities of 
the Eocene formation. Who does not know the Casnarinas of our 
greenhouses, and that those leafless, Equisetum-like, shadeless, and 
..eeping trees are almost exclusively found in New Holland? They 
also scan to have been represented in prehistoric ages, although every 
doubt respecting their former existence is not yet removed. It is 
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 vegetation, and that the dwarf Beeches of Tierra del Euego, 
Chili, Van Diemen's Land, etc., of the present day probably also ex- 
isted'formerly. I could cite many more instances ; but I will content 
myself with casting a look upon the widely-diffused and polymorphous 
class of Legnnwmcs. 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 Balhergie<£ and Ccesalpine^ are only met with m 
the tropics ; the Mimose^B form a considerable portion of the tree-vege- 
tation of New Holland; Amongst the fossils of the Eocene formation, 
we have corresponding with them the genera Plerocr.rpus, Brepano- 
carpm, CentroloMum, Balbergia, Cassia, Cmolpmta, BauJi ma, Copai- 
fera, Enlada, Jcacia, Mimosa, and Inga,— Acacia being perhaps most 
:iumerously represented.
