l P uetc^boreaUs Michauxm? Michauffis originally described this oak as Quercus ambigua (Histoire 

 des trbreS ^ forLtierS Sl^mfrique septentrionale, II, 120, pi. 24, 1812). Later discovering, as seems to 

 be shownln the English translation of the French edition of Michaux's book, that Humboldt and Bonp- 

 land hid previously used the name Quercus ambigua for a Mexican oak, Michaux appears to ha^esub- 

 Btftuted in P Srfflsh edition QuercuZ borealis for Quercus ambigua The common name > M, ^" JPg^ 

 to Quercus borealis is "Gray Oak," but as this name is now generally unknown .and as ; the tree is the most 

 northern form of the Red Oak, an appropriate common name for it would be Red Oak 

 « C S Sargent (1. c.) states that a specimen of Quercus borealis was collected in St. Tammany Parish, La.
