Anatolia] in jugo Cassio [Jebel Akra] Syrie borealis, Boissier (G). [Plate 30]

Common name:

Cyprus Oak; אלון התולע


Forests and maquis; usually preferring higher altitudes or sites with colder winters. Occurs in association with Quercus caIliprinos but sometimes also in pure stands.

Area distribution:

E. Mediterranean and W. Irano-Turanian.


In contrast to the two other local oak species, Quercus boissieri is rather uniform in its fruit characters. Outside Palestine it is exceedingly polymorphic as to its leaves, and crosses readily with other species. 

  A few wood remains of Q. boissieri were found at 4 sites in the Upper Galilee and the Golan Heights, and in Hebron (Judean Mts.) [Lophschitz 2007].
