Pig hickory or pignut are names used in several states, but without good reason.
As a name for this tree, smooth hickory would be preferable to pignut.
Besides, pignut is the accepted name of another species (Hicoria glabra).
Elsewhere the pignut and the mockernut are called "hickory."
The grafts of Davis grew on pignut stocks, are still alive and doing fairly well.
The pignut deserves the better name, "smooth hickory," a more ingratiating introduction to strangers.
The thin outer husk of the pignut is not much larger than the nut.
Country boys scorn the pignut trees, leaving their fruit for eager but unsophisticated nut-gatherers from the towns.
For my part, I never fail to show him the pignut hickory where my first golden-winged warbler spoke to me one May morning.
Grafts of all other varieties which were on the pignut stocks died the next spring.
