48. JASMINACE^. 165 



Native. Rupestral, Sylvestral, &c. The Privet is so 

 frequently planted for hedges, or for ornament in shrub- 

 beries, that its natural limit in Britain can now scarcely be 

 traced with certainty. Mr. R. B. Bowman and other 

 botanists have deemed it truly wild on the coast of Dur- 

 ham ; and Mr. Tatham says that it is abundant on lime- 

 stone cliffs about Settle. Judging by the altitude of Settle, 

 this shrub must rise almost to the superagrarian zone, and 

 may perhaps thrive in a lower temperature than the de- 

 gree of 47 indicated above.

Native. Sylvestral, Septal. Although this tree grows 

 well even to the north of Sutherland, I did not observe it 

 either in that county or Caithness, except in spots where 

 it appeared to have been planted. Balfour and Babington 

 enumerate the Fraxinus among the species seen by them 

 in the Hebrides, though as seen only in the glen of 

 Roddal, in Harris. But at page 7 of their Remarks intro- 

 ductory to their list of species, they observe, " In the glen 

 at Roddal, there is an extensive plantation of Fraxinus 

 excelsior, Qucrcus Robur, Pyrus aucuparia, and Acer 

 Pseudo-Platanus." It is impossible to decide from these
