Kutschlin ; 1 in 4 at Kadaboj, Leoben, and Bilin ; one-tkird at 
(Eningen, and half in the Pliocene. [The list of fossil genera agree- 
ing witk tkose of the Mediterranean region contains 41 names.] 
Analogues of the floras of the Temperate regions have been met 
witk in every locality, from wkick Tertiary fossil plants have been 
obtaiued. They are divided into those which are common to both, 
and those which are peculiar to one of these, the European or 
American Temperate regions. Included in the former are the ferns 
Aspidiun i and Osmunda, and a number of genera of familiär trees 
and plants, as pine, oak, beech, elm, poplar, liolly, lime, etc., the 
Tertiary forras of which correspond witk species now living both 
in Europe and America. A number of fossils on the otker kand, 
belonging to genera now common to both kemispheres, resemble 
species peculiar to one or otker only. For instance, the species of 
Myrica are all of North American aspect, the European forms not 
being represented, whilst only European forms of Castanea have 
been met wnth. 
[Tkirty-five genera are mentioned, a large proportion of which are 
monocotyledons (4 aquatic), whose analogues existed in either one 
or otker Contineut, or which cannot be referred with certainty to 
either. The list includes 2 Gymnosperms, Juniperus and Taxus. The 
most remarbable of the dicotyledons are Castanea, Ainus and Sa/aa;.] 
As representatives of the Flora of the Temperate region of the 
Western Continent, there are 37 genera, besides those common to 
Europe, amongst which are Smilax, Sabal, Platanus, Magnolia, 
Sapindus, Carya, Rhus, Juglans, Spircea, Cassia, etc. 
The Flora of the Prairie region is represented by some analogues 
of species of Querem, Populm, and four otker genera ; the Cali- 
fornian Coast region by the genus Sequoia and species of Pinus, 
Quercus, Myrica. Fraxinus , Juglans, Salix, etc. ; the Mexican region 
by species of Querem, Ficus, Symplocos, and 5 otkers; the West 
Indies by species of Sabal, Dodoncea, Celastrus, Myrtus, Cassia, and 
9 others. 
More fully represented than any of these is the Vegetation of 
tropical South America, no less than 59 genera being found ; of these 
Andromeda, Aralia, Ccesalpinia, Jlimosa, Acacia, and Sapindus are 
familiär genera. 
The Ciiilian territory is represented by few, but distinctive 
genera [11, including Podocarpus, Celastrus, and ArbutusQ 
The Oceanic Island Floras are represented as follows : — Azores, 
Madeira and Canaries by 4 ferns, Aspidium, Cheilanthes, Pteris, 
Woodwardia, and by Laurus, Dracama, and 6 other genera ; Mada- 
gascar by Andromeda and Elceodendron ; Mascarenes by Erythroxylon, 
Celastrus and E teodendron ; Sandwich Isles by Metrosideros ; Nor- 
folk Isle by Pisonia, Elceodendron, Balogliia ; New Zealand by 
Hedycarya, Panax, Weinmannia and Edwardsia.
