The wood of this species being far inferior to the true Q. Robur in 

 quality, it is highly important to distinguish them, though long 

 considered as varieties. The leaves of the present have longer, 

 more slender, footstalks, and are more equally and regularly 

 pinnatifid -, in the variety |3 they are downy underneath, and 

 generally thought more lasting, or inclined to be evergreen. 

 The most clear and indisputable specific character, noticed by 

 the older writers, consists in the fertile Jlowers having little or 

 no stalks, which difference exists likewise in the Acorns. Those 

 writers however do not appear to have been aware of the infe- 

 rior value of the timber. Professor Martyn has given some re- 

 marks on this subject, highly worthy of notice.
