This would shew that parity of conditions does not lead to a parity of productions so exact as to include identity of species, or even genera. Besides the various iso- lated regions here enumerated, there are some others indicated by naturalists as exhibiting a ve- getation equally peculiar. Some of these are iso- lated by mountains, or the interposition of sandy wastes. For example, the temperate region of the elder continent is divided about the centre of Asia, and the east of that line is different from the west. So also is the same region divided in North America by the Rocky Mountains. Abys- sinia and Nubia constitute another distinct bota- nical region. De Candolle enumerates in all twenty well-marked portions of the earth’s surface which are peculiar with respect to vegetation; a number which would be greatly increased if re- mote islands and isolated mountain ranges were to be included.
