Shingleottk. A very large valuable tree mostly cODfloed to the central part of

 ington, Wayne and Webster counties. 



€2. Qnercns imbiicaiiaXcoccinea 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 Quereus Leana Nutt.

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

 IS feet in height.
