Dict. ed. 8, 1768) appears to have been the a post- pr sor 
botanist to regard the two as distinct species: he, ever, 
erroneously applied the name Q. Robur t goths sessile- truited 
species ; in this error he was followed rm Roth, Willdenow, 
and others. Hudson (Fl. Angl. 1762) simply followed the Flora 
Suecica; whilst Martyn gave the varietal name sessilis to the 
Sessile-fruited Oak. If, therefore, the latter tree be regarded 
merely as a variety, it should be cited under Martyn’s name.
