evidently been along the southern flank of the Tibetan plateau and along the 
range which, running out from it in an easterly direction, forms the water- 
shed between the great river-systems of. S. China, the Yangtze and the West 
River. 
The fourth section, Vestitz, distinguished by the often dense strigose or 
woolly clothing of the leaves and stems, is richer in species than the other 
three combined. АП the species are connected morphologically and 
geographically with A. chinensis, which is locally common in the mountains 
of West Central China. Three closely allied species * are found in Yunnan 
at the extreme south-west of its area, while six others f are congregated along 
the coastal provinces which form its eastward limits. A. Championi, which 
occupies a unique position in this section, and, in fact, in the genus, by reason 
of its elaborate inflorescence, holds likewise an extreme geographical area 
along the south-eastern borders of the generic area from Formosa to 
Sumatra. 
The area of the whole genus thus extends from about the 50th degree 
№. latitude in Sachalien to the 8th S. latitude in Java, and from the 78th 
E. longitude in Kumaon to the eastern coasts of the continent and Japan.

dependence of the species are shown graphically in the following scheme :—
