Professor Greene considers the Washington-British Columbia form as a different species 

 from that of California, but if this is so, it is the California plant that should have its name 

 altered, as all the above names belong to the northern plant. Quercus gilberti is the low, 

 often prostrate, oak occurring alx>ut the Gulf of Georgia and locally known as vino oak. It 

 is remarkably variable in foliage, but no fruiting specimens have been found. In sheltered 

 places it assumes the ordinary form of Q. garryana. 



For an illustration of this species see Plate IX, facing page 42.
