This BioProvince (as defined by Armen Takhtajan) includes the Mongolian Altai Mountains, the basin of the Great Lakes between the Altai and Hangayn mountains, the Ala Shan, Gobi and Taklimakan deserts, the Ordos Plateau, the Tsaidam and Tarim basins and the Lob Nor depression. The Ordos Plateau situated in central-north China could be regarded as a bioprovince or sub-bioprovince in its own right and has recently been defined as one of the eight floristic endemic centers of China. Much of the northern areas of the BioProvince as whole consist of Upper Proterozoic igneous and metamorphic rocks while southern areas include Upper Ordovician fossiliferous limestone, Devonian intrusives, Permian volcanics and sandstone, and Jurassic conglomerates. The area has an arid continental climate with low levels of precipitation and wide variations in seasonal temperature. Winters are extremely cold and dry and can be virtually devoid of snow. Most of the year's precipitation occurs in summer as a result of southeasterly monsoons. Its ancient flora includes various taxonomically and geographically isolated taxa.
