This is one of our largest species of Oak, growing in the rich high land 

 ^ the upper country, 60 — 70 feet iiigh, and 3—4 feet in diameter^ covered 

 with a very dark-coloured bark, frditi whence it has derived its common' 

 name of Black Oak. Leaves on petioles about an inch long, obovate, angled^ 

 slightly and obtusely sinuate^ mucronate; glabrous on the upper surface, when 



young slightly pubescent or pulverulent on the under, afterwards only pu- 

 bescent in the axils. Nut depr^ssetf ovate, rather large. Cup deep, sessile. 



This tree appears to vary much; besides the var, Sinuosa figured by Mi- 

 chaux the elder, t. 25. and which evidently belongs to tliis species, the piatc 

 of Michaux the younger, arb, for. 2. p. 110. t. 22. seems to represent an en- 

 tirely distinct species. I have specimens of this latter variety or species sent 

 nie from Philadelphia by^Mr. Kim, as the Q. Tinctoria, which agree exactly 

 ^vith Michaux^s figur6; tliey would be Q. discolor, but they are glabrous un- 



'lerneath, and are not discoloured. 

 Gr6ws in the rich uplands of the upper country, rare along the sea-coast.
