SCHOUW'S PHYTO-GEOGRAPHIC REGIONS. 577 



number of species belonging to these two genera, by the great variety 

 of Oaks and Firs, the small number of Cruciferce and Umbelliferce, Ci- 

 t-horacece, and Cynarocephalce, the total absence of the genus Erica, or 

 heath, and the presence of more numerous species of Vaetinium, or 

 whortleberry, than are to be met with in Europe. It comprehends 

 the whole of the eastern part of North America, with the exception of 

 what belongs to the first region. It has been divided into two pro- 

 vinces: 1. That of the south, which embraces the Floridas, Alabama, 

 Mississippi, Louisiana, Georgia, and the Carolinas. 2. That of the 

 north, which includes the other states of North America, such as Vir- 

 ginia, Pennsylvania, New York, &c. Mean temperature, 54 to 72. 

 In the northern districts, down to the parallels of 55 or 50, there is 

 no cultivation. South of this line, the cultivation is the same as in the 

 second region. Maize is cultivated to a greater extent in North 

 America than in Europe. 



5. The Region of Magnolias, comprising the most southern parts of 

 North America, between 36 and 30. The tropical forms which show 

 themselves more frequently than on a similar parallel of the old con- 

 tinent, are the chief feature in the vegetation. Thus we meet with 

 Anonacece, Sapindacece, Melastomacece, Cactacece, and Zingiberacea: 

 This region has fewer Labiatce and Caryophyllacece than occur in cor- 

 responding latitudes in the Old "World. It presents more trees with 

 fine blossoms, and shining, sometimes pinnated, leaves, as Mangoli;i, 

 Tulip-tree, Horse-chestnut, Eobinias or False Acacias. Mean temper- 

 ature, 59 to 72. The same plants cultivated as in the third region. 

 Rice is much cultivated. In the southern district, the Sugar-cane is 

 productive ; and, in the eastern districts, Cotton is grown to a great 

 extent. 



6. The Region of Caiwlliacece and Celastracece, or the Japanese re- 

 gion. This region is as yet too little known to enable us to determine 

 accurately its characteristic features. It embraces the eastern temper- 

 ate part of the old continent, namely Japan, the north of China, and 

 Chinese Tartary, between lat. 30 and 40 north. Its vegetation ap- 

 pears to occupy a middle place between that of Europe, and that of 

 North America, approaching more to the tropical than to the European. 

 It has an affinity to the Indian Flora, as shown by the occurrence of 

 Bananas, Palms, Zingiberacece, Anonacece, Sapindacece, and Cycadacece. 

 We meet with Eriobotrya japonica or Loquat, Tea, and various species 

 of Citrus. Mean temperature, 54 to 68. The cultivated plants are 

 Rice, Wheat, Barley, Oats, Millet, Buckwheat, Apple and Pear, 

 Quince, Plum, Cherry, Apricot, Peach, Loquat. Orange and Shaddock, 

 Melon, Tea, Hemp, Paper-Mulberry, Cotton, and False Sago. 



7. The Region of Zingiberacece, or the Indian Flora. Zingiberacea 

 here are much more numerous than in America, as well as Leguminosa:, 

 Cucurbttacece, and Tiliacece, although in a less degree. In consequence
