 dioecious, bearing petals in both sexes. (Don's Mill.) A deciduous, sub-

The root fixes itself so firmly in the fissures of the 

 rocks, that the plant can scarcely be pulled up. The 

 stem divides immediately into branches, that are very 

 much subdivided, and form a very close head, the 

 shoots having numerous spines, both terminating and 

 lateral. The berries are used for dyeing leather yel- 

 low ; and the Turkey leather, or yellow morocco, is 

 generally supposed to be coloured by them. Zdl - h mnus s
