•'"' The rock chestnut oak, commonly called Q. Prinus. 



•5 Commonly written Q. M or elms, but evidently an adjective name based 

 on Moreh — the Scriptural " land of Moriah," and consequently to be brought 

 into agreement of gender with the feminine tree name Qucrciis. 



' Though pagodccfolia, applied bj^ Ashe to this species, has priority in 

 varietal use, it gives way under the international rules to Rafinesque's spe- 

 cific name Pagoda.
