 Britt. 



Range : 16, 20, 22, 25, 29, 30.

A large tree ; taproot short, root system spreading ; usually occurs on fertile 

 soil; comparatively rapid growing (fora hickory), long-lived; ability to stump 

 sprout decreases with age ; easily frost-damaged ; somewhat injured by bark 

 beetles ; wood much inferior to other hickories, unimportant commercially 

 although somewhat used for fuel ; nuts probably do not mature northward 

 because of frost ; difficult to transplant ; most cultivated forms, of which there 

 are about 100 named varieties, have larger nuts with thinner shells than the 

 wild species; 100 seeds per pound, germination about 85 percent; about 35 

 usable plants per pound of seed ; a hybrid between this and C. laciniosa is 

 recognized as the Nussbaumer hickory and between this and C. cordiformis as 

 Brown's hickory.

 of birds including wild turkey ; bassariscus, peccary.
