CUPU LI FERAE 129 



lOE. Frequent, but not abundant except in Dale County, 

 low. Rare, mostly on Buhrstone ridges. Wilcox, Monroe and Choc- 

 taw Counties.

12. Common throughout. 



13. Very common. 



Quercus Marylandica, Muench. (Q. niyra of most 19th cen- 

 ttiry authors. Q. fcrruginca, Ait.) 



(Round-leaf) Black-jack. (Dollar-leaf Oak) 



(Fig. 31) 



A well-known rugged-looking tree of medium size, ranging 

 from scarcely more than a shrub to a foot or two in diameter. In 

 late winter when its leaves are off it looks much like the other 

 black-jack, Q. Caicsbaci. Like that species, its principal use is 

 for fuel. 



If there is any tree that specially prefers ferruginous soils (a 

 point not yet demonstrated, however), this is it. Its rusty-looking 

 leaves and black bark suggest iron, and it grows especially on red 

 clay hills, and in other very dry soils, but not in quite sttch poor 

 soils as the preceding, though the two are often associated. It 

 seems to be almost as indifferent to fire as Q. Catcshaci is.
