Querqus acuminata. — The Chestnut or Yellow Oak (name 
in Gray’s Manual Quercus Muhlenbergii) is described as “a tall tree 
with thin flaky bark” (Gray), or “ a tree with gray flaky bark” 
(Britton); and in fact many of the White Oaks are said to have 
“ flaky ” bark. The Quercus acuminata is very abundant in central 
Ohio and is of common occurrence in many parts of the State. It is 
rare that the “flakiness” of the bark or a tendency to separate in 
plates, is pronounced or conspicuous in our Chestnut Oak trees. The 
single good example I have found is here shown in Fig. 1 reproduced 
Fig 1. Fig. 2. 
from a photograph of a specimen growing in Hayden’s ravine near 
Columbps. Both trees shown are the same species but the smaller 
one has merely furrowed, not flaky, bark, and it is a fair represen- 
tative of the trunks of this Oak as they occur in our vicinity. The 
usual form of bark is perhaps more clearly shown in Fig. 2, which 
is from a photograph of a large ti’ee standing near the Horticultural 
Hall of the Ohio State University. This specimen has leaves re- 
markably narrow for Q. acuminata but the trunk is similar in 
appearance to the trees which have broad leaves.
