Black Oak. 



Yellow-barked 



Oak. 



Red Oak. 



Inner bark reddish; scales of involucre, brown, glabrate, appressed. In 

 the C, this species blossoms and puts forth its leaves about two weeks 

 earlier than the next, and the leaves are smooth and glossy before the 

 leaves of the next have become well divested of their reddish down. 



Frequent. 



1008. tinctoria, Bartram. ( * ) 



Inner bark bright yellow; scales of involucre yellowish-canescent, some- 

 what squarrose; leaves less pinnatilid, more obovate in outline and less 

 glossy-green than those of Q. coccinea. This species and the preceding 

 occur together in the C. and are seldom large— usually 40-50 ft., and 12- 

 15 inches in diameter. Considerable study has shown no gradations be- 

 tween the two forms, except one anomalous specimen, with very 

 long acorns, and some characteristics of both species. 



1009. rubra, L. (***) 



Th. 



Wood reddish, coarse; used chiefly for fence rails and fuel. In the C. & 

 S., a large tree; in the N. either a very large tree, (Emmet Co.— 

 Winchell), or, at Petoskey, a low tree or tall shrub(!); in U. P., along 

 the shore, a low shrub or scraggy tree (the common form), or, in Onton- 

 agon valley, a good-sized tree— VVhitney. Q. ambigua, Mx., apparently 

 belongs here.— (See Engelm. " Oaks of the U. S." Tr. Ac. Sc, St. Louis, 

 Vol. III.) "One of the most variable of the Atlantic species."— Engel-
