Prof. Dr. von Ettingshausen— Tertiary Flora of Australia, 155 
fossil plants from Risdon, Geilston Quarry, and Shoebridge’s Lime 
Kiln, ete., near Hobart Town. The first is one of the best localities for 
the Travertin containing the leaves. In the British Museum there isalso 
preserved a series of fossil plant-remains which are labelled “ Hrebus 
and Terror,” and were collected during the exploring voyage of those 
vessels to the Antarctic Seas, by Dr. C. McCormick, who was attached 
as Surgeon and Naturalist to the “Erebus.” The fossil plants I 
examined came from the Tertiary Travertin which is so extensively 
developed in the neighbourhood of Hobart Town. Finally I have 
also examined the figures in R. M. Johnston’s Paper No. 5, with the 
view of enlarging the knowledge of this interesting fossil flora. 
It contains till now 35 species, which are distributed into 21 genera 
and 17 families. Of the species I have to mention :—Araucaria 
Johnstoni, v. Muell., Myrica Eyrei, closely allied to M. salicina of the 
European Miocene ; Betula Derwentensis corresponding to the Miocene 
B. Brongniartii ; Alnus Muelleri, nearly allied to the Miocene A. 
gracilis; Quercus Tasmanii like the Q. Palgococcus of the fossil flora 
of Radoboj; Fagus Risdoniana, nearly allied to F. Deucalionis ; Salia 
Cormickit closely allied to S. varians; Cinnamomum Woodwardit, 
allied to the Miocene C. Scheuchzeri; Lomatia pre-longifolia, allied 
to L. borealis of the European, and to L. Torrey: of the American 
Tertiary flora; as well as to the living Australian L. longifolia ; 
Dryandroides Johnstoni, referring to living species of Banksia and 
Dryandra; Coprosma pre-cuspidifolia, the ancestral species: of the 
living C. cuspidifolia, of Australia; LHchitonium obscurum allied to 
E. macrospermum of the European Miocene Flora; Elgocarpus Bassit 
nearly allied to the Miocene EH. Albrechti; Sapindus Tasmanicus 
allied to S. falcifolius of the European Miocene; Cassia Flindersit 
allied to C. ambigua of the same strata. Besides these species of 
Apocynophyllum, Cordia, Premna, Sapotacites, and Ceratopetalum occur. 
This flora contains more characteristic genera referable to the living 
Australian flora than that of Dalton, in New South Wales, especially 
such genera as Lomatia, Dryandroides, Coprosma, Ceratopetalum, but 
with a great number of genera occurring in the Tertiary flora of 
Europe, North America, and North Asia. The species are mostly 
allied to Miocene, and therefore the leaf-beds of the Tertiary 
Travertin belong, I believe, to the Miocene formation. 
The result of my report is as follows. I find that the Tertiary 
flora of Australia is far more nearly allied to the Tertiary floras of 
the other Continents than to the living flora of Australia. It seems, 
therefore, that the numerous forms which characterize the latter have 
been developed out of Pliocene or Post-Tertiary forms of plants till 
now unknown to us. The recent flora of Australia contains also 
genera which characterize other floras, but not the Australian. It 
was till now enigmatical how they came to form part of this recent
