Kutschlia ; 1 in 4 at Eadaboj, Leoben, and Bilin ; one-third at 

 GEuingen, and Lalf in the Pliocene. [The list of fossil geneva agree- 

 ing with those of the Mediterranean region contains 41 names.] 



Analogues of the floras of the Temperate regions have been met 

 with in ever^' locality, from which Tertiary fossil plants have been 

 obtained. 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 

 Asjjidium and Osmimda, and a number of genera of familiar trees 

 and plants, as pine, oak, beech, elm, poplar, holiy, lime, etc., the 

 Tertiary forms of which correspond with species now living both 

 in Europe and America. A number of fossils on the other hand, 

 belonging to genera now common to both hemispheres, resemble 

 species peculiar to one or other 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 with. 



[Thirty-five genera are mentioned, a large pi-oportion of which are 

 monocotyledons (4 aquatic), whose analogues existed in either one 

 or other Continent, or which cannot be referred with certainty to 

 either. The list includes 2 Gymnosperms, Janiperus and Taxus. The 

 most remarkable of the dicotyledons are Castanea, Alnus and Salix.'] 



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, Sahal, Platanus, Magnolia, 

 Sapindus, Carya, Rhus, Juglans, Spircsa, Cassia, etc. 



The Flora of the Praikie region is represented by some analogues 

 of species of Qmrcus, Populas, and four other genera ; the Cali- 

 FORNiAN Coast region by the genus Sequoia and species of Pinm, 

 Qaercus, Myrica. Fraxinus, Juglans, Salix, etc. ; the Mexican region 

 by species of Quercus, Ficus, Symplocos, and 5 others; the West 

 Indies by species of Sahal, 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, Mimosa, Acacia, and Sapindus are 

 familiar genera. 



The Chilian territory is represented by few, but distinctive 

 genera [11, including Podocarpus, Celastrus, and Arbutus.^ 



The Oceanic Island Floras are represented as follows : — Azores, 

 Madeira and Canaries by 4 ferns, Aspidium, Cheilanthes, Pteris, 

 Woodwardia, and b}'- Laurus, Braccena, and 6 other genera ; Mada- 

 gascar by Andromeda and Elcsodendron ; Mascarenes by Erythroxylon, 

 Celastrus and E'ceodendron ; Sandwich Isles by Metrosideros ; Nor- 

 folk Isle by Pisonia, El(Bodendron, Baloghia ; New Zealand by 

 Hedy carya, Panax, Weinmannia and Edwardsia.
