Obs. It has been the late of this remarkable tree to have been 

 overlooked for more than 200 years after the time of Clusius, and then 

 to have been almost simultaneously rediscovered , and described un- 

 der a multitude of names by various authors. This too is the more 

 singular as regarding a tree which produces an object of primary 

 importance, namely ihe gallnuts of commerce. Clusius indeed re- 

 marks « galli autem extremis ramulis nascuntur , iis quae in ofiicinis 

 venales reperiuntur, perquam similes; » and in fact when compared 

 with the quercus infectoria , both as originally collected by Olivier, 

 and as found hy Labillardiere in Syria, and by myself and Mr. Parolini 

 in Phrygia, the Spanish plant turns out to be identic with the levant 

 species, whose product is so universally employed. This oak begins to 

 appear both in the eastern and western portion of the old world between 

 the 41 and 42 degrees of northern latitude. It does not seem to pass 

 the Pyrenees in the west, and in the east I found it to the north of 

 Constantinople in the valley of Domouz Dereh which opens on the 

 Black sea. How much further northwards it mounts in this direction 

 I am unable to say. It descends as far south as Syria, but how far it 

 follows in the west the chain of Mount Atlas cannot be yet ascertained. 

 It is not indigenous in the Canaries, but as well as the chestnut has 

 been introduced by the Spanish colonists. 



Like all its congeners this species is exceediugly variable , yet its 

 variations may be followed from the eggshaped subspinous leaves
