As compared with the vegetation of the Ulex europmus areas, it 

 will be seen that the U. Gallii ground does not show any appreciable 

 diminution as regards the total number of species present ; the most 

 marked change is the smaller stature of the plants, the absence of tall- 

 growing species, and of such as have large leaves; in short, a tendency 

 to more pronounced xerophytism in character.
