§ VII. THE GARDEN OF NATURALIZATION. 



Adjoining the Seed-garden and on the same le- 

 vel is that for the naturalization of foreign plants, 

 which is 1 32 feet long, and of the same breadth 

 as the preceding at the entrance, but narrower 

 towards the other extremity. On the eastern 

 side, which is sheltered from the north and west 

 by the walls and by the arbor-vitae hedge, are 

 exposed, during the summer, the greater part of 

 the trees and shrubs from New Holland, which 

 have passed the winter in the green-house, the 

 metrosideros, the melaleuca, the leptospermum, 

 the eucalyptus, the banksia, the embothrium, etc. 

 Under the walls of the three remaining sides, 

 which are i5 feet in height, are placed different 

 trees and shrubs according to the exposure ; thus 

 on the south we see the pistacia-tree, the zizi- 

 phus, the pomegranate, the ephedra altissima(\), 

 brought from Barbary by M. Desfontaines, a 



(i) A leafless shrub, with slender, pendent, ever-green branches, 

 which climbs upon other trees, aud covers them with thick tufts.
