SOUTHERN LIMIT OF CHESTNUT OAK ^-'' 



RT-fH 1926 



AIap 13. Southern limit of Oucrcus iiwtitaiia. 



6B. Tuscaloosa, Hale and Bibb Counties.

Qiicrciis Bcrnardicnsis, Wolf (Torreya 18:161-162. 1918), 

 described from Cullman County, is now believed by its author to 

 be a hybrid between Q. montaua and Q. stcUata. I have seen what 

 I took to be the same hybrid, in company w-ith both parents, at the 

 type-locality (192T). on rocky hills near the Warrior River about 

 twelve miles above Tuscaloosa (1926), in a ravine between Maud 

 and Trio, Bibb County (1924, and seen from train in subsequent 

 years), and at Tallassee (1906). 



What appears to be a hybrid between Q. alba and Q. moutana 

 (Q. Saulci, Schneider?) grows on a stratum of sandstone between 

 limestones on the northwest slope of Lookout Mountain near Val- 

 ley Head, DeKalb County.
