southwestern part of the State. Dr. Schneck reported it from 

 Gibson and Posey counties as very rare. Rid^way reports it from 

 Gibson County as common in clayey and poor soil but rare in rich 

 soil. He remarks that the bark of the specimens found in rich 

 soil was light and scaly, like that of the white or chinquapin oaks, 

 while the bark of those found on clayey soil was darker and re- 

 sembled that of the true black oaks. In Point Township in Posey 

 County, in which Dr. Schneck did not work it is the most common 

 oak. It is usually found in low ground and is associated with 

 Quercus bicolor, Quercus palustris, Quercus Schneckii, Quercus 

 stellata and Quercus velutina. The whole of this township is low 

 and a peculiar feature is to find the preceding oaks intimately 

 associated. In this locality it is one of the largest trees, frequently 

 attaining a diameter of 10 dm. (40 inches). Sometimes the lower 

 branches shade off tardily which gives the tree the appearance of 

 the pin oak. 



This is the Spanish oak of text books, but no [one in this State 

 was found who recognized it by that name. A majority of the 

 persons questioned answered that it was a ^'kind of a black or red 

 oak." 



This species by some authors has been divided into two species, 

 but it is believed the characters on which the division is made are 

 not constant. A study of hundreds of trees in the lower part of 

 Posey County in May, September and November shows that the 

 bark will vary from a light to a very dark gray; that the leaves on 

 the same tree will sometimes vary from 3-lobed to 11-lobed, and 

 the bases from rounded or truncate to wedge-shaped. Trees that 

 have the 3-5 lobed type of leaves with a rounded base on the lower 

 branches will also have in the top the more characteristic 7-9 lobed 

 leaves with a wedge-shaped base. 



The published records of the distribution are as follows: Foun- 

 tain (Brown); Gibson (Ridgway) and (Schneck); Posey (Schneck). 



Additional records are: Posey (Deam).

 Peach Oak. Jack Oak. Water Oak. Plate 59. Bark on the

 nearly black; branchlets at first hairy, becoming smooth, gray, 

 reddish or a dark brown; winter buds ovoid, pointed at the apex, 

 about 3 mm. (J^ inch) long, reddish brown, scales ciliate; leaves 

 elliptic to oblong-lanceolate, sometimes somewhat falcate, 8-16 cm.
