576 SCHOUW'S PHYTO-GEOGRAPHIC REGIONS. 



2. The Region of Umbelliferce and Cruciferce. These tribes are here 

 in much greater number than in any other region ; Rosacece, Ranun- 

 culacece, Fungi, Amentacece, and Conifera?, likewise very numerous; the 

 abundance of Carices, and the fall of the leaves of almost all the trees 

 during winter, form also important features of this division. It may be 

 separated into two distinct provinces: 1. The province of the Cichor- 

 acece, which embraces all the north of Europe, not comprehended in 

 the preceding region, namely, Britain, the north of France, the Nether- 

 lands, Germany, Denmark, Poland, Hungary, and the greater part of 

 European Russia, 2. The province of the Astragali, Halophyta, and 

 Cynarocephalce, which includes a part of Asiatic Russia, and the coun- 

 tries about the Caucasian and Altai mountains. Mean temperature, 

 36 to 57. The cultivated plants are Rye, Barley of different kinds, 

 Oats, Wheat and Spelt, Maize, Millet, the Potato, Buck-wheat, Apple 

 and Pear, Quince, Cherry, Plum, Apricot, Peach, Mulberry, Walnut, 

 Vine, Gooseberry and Currant, Strawberry, Cucumber and Melon, 

 Cabbage, Mustard, Pea, Bean, Beet, Spinach, Carrot, Flax, Hemp, 

 Trefoils and Vetches, Rye-grass, &c. 



3. The Region of Labiates and Caiyophyllacece, or the Mediterranean 

 Flora. It is distinguished by the abundance of the plants belonging 

 to these two orders. Composites, Galiacece, Boraginacece also occur in 

 considerable quantity. Some tropical families are also met with, such 

 as Palms, Laurels, Aracece, Anacardiacece, grasses belonging to the 

 genus Panicum (millet), and some Cyperacece. Solanacece, Malvacea>, 

 Leguminosce, Urticacece, and JEuphorbiacece increase. The forests are 

 composed chiefly of Amentacece and Coniferce, as birches, oaks, firs, 

 &c., the copses, of Ericaceae (the heath tribe,) and Anacardiacece, as 

 the mastich. We meet in this region with a great number of ever- 

 green trees. Vegetation never ceases entirely, but verdant meadows 

 are more rare. Schouw divides this region into five provinces : 1. 

 The province of the Cistuses, including Spain and Portugal. 2. The 

 province of the Salvice and Scabiosce, the south of France, Italy, and 

 Sicily. 3. The province of the Shrubby Labiates, the Levant, Greece, 

 Asia Minor, and the southern part of the Caucasian countries. 4. The 

 Atlantic province, the north of Africa, of which he does not yet know 

 any distinctive character. 5. The province of Semperviva, the Canary 

 Isles, and probably also the Azores, Madeira, and the north-west coast 

 of Africa ; many Sempervivums, and some Euphorbias with naked and 

 spiny stems particularly characterize this province. Erica arborea, 

 and Pinus canariensis are found here. Mean temperature, 54 to 72. 

 Cultivated plants are the same as in the second region, with the addi- 

 tion of Rice, Guinea Corn, Italian Millet, Fig, Almond, Orange and 

 Lemon, Water Melon, Olive, Cotton. Rye and Buck- wheat are only 

 cultivated in the mountainous regions. 



4. The Region of Asters and Solidagos. This is marked by the great
