standing in a field about 3 miles east of Medora, Jackson County. It has 

 been found in Lawrence County by Kriebel and in Knox County by 

 Friesner. 



X Quercus Deamii Trelease. This is believed to be a hybrid between 

 Quereus alba and Quercus Muhlenbergii. A tree was discovered in a woods 

 about 4 miles northwest of Bluffton, by L. A. Williamson and his son, E. B. 

 Williamson. About a third of an acre of ground on which this tree stands 

 was bought and donated to the state. The tree has borne viable nuts and 

 seedlings have been planted in the space about the tree to perpetuate it. 

 Graft wood has been distributed so that the identity of the tree will be 

 preserved. 



X Quercus Fernowii Trelease. This is evidently a hybrid between Quer- 

 cus alba and Quercus stellata. A tree was found by Carl M. Carpenter on 

 a wooded ridge along Fire Lane 9 in the Brown County State Forest about 

 10 miles southeast of Nashville, Brown County. 



X Quercus Jackiana Schneider. This is evidently a hybrid between Quer- 

 cus alba and Quercus bicolor. I found a specimen of this form in the woods 

 of J. M. Hopper about 2 miles northeast of Onward, Cass County. There 

 is another in the Deam Arboretum at Bluffton, Indiana, where it grew 

 from Indiana seed planted there. 



2. Quercus prinoides Willd. Dwarf Chinquapin Oak. Map 781. I 

 found this shrub in Elkhart County while inspecting the Cooley Lake 

 Club land in company with T. E. Shaw and Glenn B. Banks. The woods 

 is about 6 miles northeast of Elkhart and about a quarter of a mile south 

 of the Michigan state line. The shrub was plentiful in the north part of 

 a cut-over woods in the southeast quarter of section 10 where it was 

 growing in very sandy soil with black oak and white oak. I was not able 

 to ascertain how widely it is distributed. This species has been reported 

 from Cass County in Michigan which joins Elkhart County on the north.

3. Quercus bicolor Willd. Swamp White Oak. Map 782. This species 

 is more or less frequent throughout the state although there are no reports 

 from Benton, Jasper, and Newton Counties. In the northern part of the 

 state, it is usually found on a "gumbo" hardpan soil associated most com- 

 monly with pin oak. In the southern part of the state in the "flats," it is 

 found in hard, white clay soil with pin oak and swamp chestnut oak.

X Quercus Schuettei Trelease. This is believed to be a hybrid between 

 Quercus bicolor and Quercus macrocarpa. This hybrid is known from a 

 specimen collected by R. M. Kriebel from a single tree in Lawrence County. 



4. Quercus Muhlenbergii Engelm. Chinquapin Oak. Map 783. In 

 northern Indiana this species is called sweet oak. Infrequent to rare in 

 all parts of the state although Hill's report from Lake County is the
