The northern provinces of China, Mr. Royle observes, are more European 

 in their flora than any parts of the plains of India ; and the flora of the moun- 

 tains has an almost universal identity of genera with that found covering the 

 elevated belt of Himalaya. From these and other remarks we conclude that 

 many species of trees and shrubs in China, now wholly unknown to us, will at 

 some future time be added to the British arboretum. 



The Chinese, through the European residents at Canton and other sea- 

 ports, have become possessed of various of our ornamental ligneous plants. 

 Mr. Reeves (Gard. Mag., vol. xi. p. 437.) mentions that Magnolia grandiflora 

 was introduced at Macao by Mr. Livingston, previously to 1830; and M. 

 acuminata, glauca, and tripetala, soon afterwards. The recent discovery of 

 the tea shrub in the province of Assam, through an extent of territory which 

 occupied a month's journey, shows how little of the ligneous flora of that part 

 of the world is yet known. (See Dr. Wallich, in Gard. Mag., vol. xi. p. 429.) 



Sect. II. Of the Indigenous and Foreign Trees and Shrubs of 



Africa, 



The number of ligneous species which the British arboretum has obtained 

 from Africa, including the Canary Isles, appears to be 23 ; a number larger 

 than might be expected, considering the tropical situation of this part of the 

 world, and that its mountains are less elevated than those of Asia. Barbary 

 has supplied 13 of these 23 species; because, being situated on the shores of 

 the Mediterranean, its climate is comparatively temperate. More may, per-
