61. Quercus imbricaria Michx. 



Shingle oak . A very large valuable tree mostly confined to the central part of 

 the State, where it reaches its greatest development. In the early days much used 

 for making fchingles, wherce the common name. It is found in Adair, Bollinger, 

 Boone, Butler, Cape Girardeau, Carroll, Cass, Clark, Clay, Clinton, Daviess, 

 Dunklin, Greene, Howell, Jackson, Jeflerson, Linn, Livingston, Madison, Miller, 

 Oregon, Pike, Ray, Scotland, St. Francois, St. Louis, Stoddard, Sullivan, Wash- 

 ington, Wayne and Webster counties. 



62. Quercus imbricaiiaXcoccinea Engelm. 



A hybrid between the Shingle-oak and the Scarlet-oak. This has undoubtedly 

 been found in the State, and I question very much if one of the supposed parents 

 is the Scarlet-oak. Has been found in Butler, Pettis, St. Louis and Wsshington 

 counties. This is Quercus Leana Nutt. 



€3. Quercus imbricaria Xpalustris Engelm. 



A hybrid between the Shingie-oak and the Pine-oak ; has been found in St. 

 Louis county.

A hybrid between the Shingle oak and the Red-oak ; has been found in Jack- 

 son county. 



65. Quercus lyrata Walt. 



Overcup-oak. A large valuable tree in the lowlands of the southeastern part 

 of the State, where it has been found in Butler, Cnpe Girardeau, Dunklin, Missis- 

 sippi, New Madrid, St. Louis and Wayne counties. 



66. Quercus macrocarpa Miclix. 



Bnr-oak. One of our largest, and next to the White-oak, the most valuable of 

 our oaks. Distributed over the whole State, but most abundant along the Missouri 

 river in the bottoms. A pretty fair idea of its range in the State may be had, 

 when we know that it has been found in Adair, Andrew, Atchison, Cape Girar- 

 deau, Cedar, Clark, Clay, Clinton, Daviess, Dunklin, Greene, Howard, Jackson, 

 Jasper, Lawrence, Madison, McDonald, Mississippi, New Madrid, Oregon, Pike, 

 Platte, Ray, Scotland, Shannon, St. Louis, Sullivan, Vernon and Wayne counties. 



67. Quercus macrocarpa oliyseformis (Micbx. f. ) A. Gray. 



Dwarf bur-oak. A very much dwarfed variety of the last, with smaller oblong 

 acorns and densely pubescent twigs and leaves, which has been found on the sides 

 and tops of the peculiar loess mounds in Atchison county. A small bushy tree 8 to 

 18 feet in height. 



68. Quercus macrocarpa XMublenbergii B. F. Bush. 



A hybrid between the Bur-oak and the Chinquapin oak, of which two trees 

 are found in Jackson county.
