LEA’S OAK. 
leaves larger and more obtuse at base. These modifi- 
cations (if it is a hybrid) may be derived from the long 
petioles and -larger leaves of the Black and Scarlet Oaks. 
I think it does not partake of Quercus phellos, (Willow 
Oak,) a species that does not grow, to my knowledge, 
within several hundred miles of this place (Cincinnati).” 
“I saw two individuals of Q. phellos in the Bartram 
garden, which Colonel Carr assured me were propagated 
from the seed of the original Bartram Oak. Certainly 
our plant is very like Michaux’s figure; but as that 
appears to be a hybrid of Q. phellos , I think they must 
be considered distinct. If ours be a hybrid, it most 
likely comes from Q. imbricaria and Q. tinctoria , or 
coccinea” 
“I have found but a single stock of this (about five 
years ago). It grows three miles north of Cincinnati.” 
I confess I see too little resemblance in our plant 
with Q. imbricaria , to agree with my friend Mr. T. Lea, 
as to any hybrid connection with that remotely allied 
species. Betwixt the Grey Oak, (Q. ambigua, Mich.,) 
and Q. tinctoria , I perceive a nearer resemblance. The 
fruit appears to be wholly that of the Grey Oak. The 
gland in both is striated, and with a small conic projec- 
tion. In our plant, however, the base of the gland and 
that of the cup are yellow, indicating its alliance to Q. 
tinctoria. The leaf differs wholly from both in its simple 
undivided lobes, though the long petiole and rounded 
base is that of tinctoria. Scarce as this species yet 
appears to be, under the present circumstances, I am 
inclined to believe it of a distinct race, with features as 
distinct as any species in the genus. For the Grey Oak 
being, I believe, unknown in Ohio, is again out of the 
question. I suspect it is in all physical respects allied 
to tinctoria , and would equally afford a yellow dying 
material.
