I have thought it advisable to adopt the characters of our sup- 
posed three oaks as given by the lamented Prof. Don in Leighton's 
Shropshire Flora and must refer to that excellent work for a de- 
tailed account of them. See also a highly valuable paper by 
Dr. Greville in Trans. Bot. Soc. Edin. i. 69.
