Juniper ns thurifera occurs wild in South-eastern France, Spain, 

 Portugal, Sardinia, Morocco and Algeria. It is common on the 

 mountains of Central and Southern Spain, occasionally forming pure 

 open woods. 



This species was cultivated by Miller in 1752, but is rare now in 

 England, apparently only thriving in warm and sheltered situations. 



The photograph represents a specimen from a tree at Bayford- 

 bury. It was planted in 1841 and is now 32 feet high.
