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 photograj^h of a specimen growing in Hayden's ravine near 

 Columbus. 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 jDhotograph of a large tree 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.
