An entirely newlight was thrown on many problems, and the headquarters ofseveral genera, such as, for example, Rhododendron, Lilium,Primula, Pyrus, Rubus, Rosa, Vitis, Lonicera, and Acer,heretofore attributed elsewhere, was shown to be China. This extraordinary wealth of species exists, notwith-standing the fact that every available bit of land is undercultivation. Below 2000 feet altitude the flora is every-where relegated to the roadsides, the cliffs, and other moreor less inaccessible places. It is impossible to conceive theoriginal floral wealth of this country, for obviously manytypes must have perished as agriculture claimed the land,not to mention the destruction of forests for economicpurposes. In order to summarize the account of this wonderful flora. THE FLORA OF WESTERN CHINA 5 it is convenient to divide the region into altitudinal zonesor belts. The mountainous nature of the country lends itselfadmirably to such an arrangement, and it is perhaps the onlyfeasible way of dealing with a subject so vast and chart (p. 7) represents an ideal section of the region andmay possibly convey a clearer idea of the subject than thetext which follows :— Division i.— The belt of cultivation—2000 feet climate of the Yangtsze Valley, up to 2000 feet altitude,is essentially warm-temperate. Rice, cotton, sugar, maize,tobacco, sweet potatoes, and legumes are the principal summercrops; in winter, pulse, wheat, rape, hemp, Irish potato, andcabbage are generally gro^^^l.
