tected in temperate South America. Other instances are 

 Camellia, Deutzia, Hydrangea, Viburnum, several Cornea, and 

 Houttuynia. 



The recent able investigation of the Hongkong Flora by 

 Major Champion and Mr. Bentham has materially increased 

 our knowledge of the intimate relationship between the 

 Floras of China and the eastern parts of India ; amongst 

 many instances, we may select the remarkable genus of Ferns, 

 Bowringia*, found in Hongkong and in the Khasia moun- 

 tains ; Wikstroemia, a genus of Baphnece ; Bucklandia, Enki- 

 anthus, Henslovia, Scepa, Antidesma, Benthamia, Goughia, 

 Myrica, and very many others ; in fact, there is scarcely a 

 genus in the whole Hongkong Flora that is not also Indian. 

 Euryale ferox, which is wild in the Gangetic delta, and is 

 found as far westward as Kashmir, is abundant in China ; and 

 Nepenthes phyllamphora, a native of the Khasia mountains, 

 is also found at Macao, and eastward to the Louisiade Archi- 

 pelago. 



4. The Siberian type. — This is characteristic of the colder 

 temperate parts of Asia, and is very fuUy represented in the 

 upper temperate and alpine regions of the Himalaya, de- 

 scending in the north-western and drier parts of the chain to 

 very low levels. It approaches, in many respects, to the 

 South European vegetation, but is characterized by the pre- 

 dominance of FuniariacecR, Potentilla, Legmninosm, especially 

 Hedysarum and Astragalece, of Umbelliferce, Lonicera, Arte- 

 misia, Pedicularis, and Boraginece ; and by the rarity or total 

 absence of certain groups or genera which are especially 

 abundant in Europe, such as Cistacem, Rosa, Rubus, Trifolium, 

 Erica, Ferns, and other cryptogams. As the Alps of Central 

 Asia rise gradually from the elevated tracts of Southern Sibe- 

 ria, and possess a very similar climate, the increasing elevation 

 compensating for the diminution of latitude, a very Siberian
