GIBRALTAR PLANTS. 145 



PHYTOLACCE^l, R. Brown. 



Phytolacca dioica, L. 



Vulg. Bella sombra, Sp. 

 Hab. South America. 



OBS. This is one of the many foreign plants introduced into 

 Gibraltar by General Don. This tree arrives at great perfection 

 on the rock, and, from its thick foliage affording so much shade, 

 it is a very valuable tree in that climate. It has likewise been 

 introduced into Malaga. There is also a very healthy^specimen 

 of the P. decandra in the garden of the Colonel of Engineers ; 

 and it grows almost wild on the hills of Ronda. The term 

 pepper-wood or pepper-tree is not applied (as Boissier states) to 

 the P. dioica, but to the Schinus molle.
