I. GENERAL. 



Those parts of the temperate zones bordering on the tropics and alone 

 meriting the appellation subtropical exhibit scarcely marked characteristics, 

 and ally themselves with tropical districts when the climate is very humid, 

 and with the true temperate districts when it is dry. With increasing 

 distance from^th£ tropics_a_new factor intervenes, the cold of winter, which, 

 tHough acting more indirectly than atmospheric precipitations and sub- 

 ordinate to them, assists in determining the differentiation of the vegetation 

 in oecological districts. It is no longer, as in the tropics, a matter of 

 indifference whether the rainy season occurs in summer or in winter, but the 

 rainy season is responsible for an essential distinction in the oecological 

 conditions of the vegetation. 



Excluding the less characteristic subtropical districts, the warm temperate 

 districts may be subdivided into three groups, namel}', those without any 

 dry season, those with a moist summer, and those with a moist winter. 

 Intermediate districts, usually of slight extent, with spring or autumnal 

 rains, sometimes ally themselves more to districts with a moist winter and 

 at other times to those with a moist summer. 



2. SUBTROPICAL DISTRICTS. 

 Temperate districts bordering on the tropics, up to about 30° latitude, are 

 chiefly occupied by desert. In them high-forest districts prevail over only 

 a limited area. Concerning the climatic condition of these high-forest 

 districts I cannot give a satisfactory account from the literature before me ; 

 a rainfall of 130-150 cm., with the corresponding atmospheric humidit}-, 

 appears sufficient for fairly rich forest growth. Nevertheless, countries with
