TAXONOMY : 
The currently accepted scientific name of pignut hickory is Carya glabra
(P.Mill.) Sweet.  It is a member of the walnut family Juglandaceae.
Three varieties are commonly recognized [25]:

      Carya glabra var. glabra
      Carya glabra var. hirsuta (Ashe) Ashe
      Carya glabra var. megacarpa (Sarg.) Sarg.

The variety hirsuta, or alternately a fourth variety identified as Carya
glabra var. odorata (Marsh.) Little, is frequently considered synonymous
C. ovalis, red hickory [6,32,51].  The taxonomic relationship between C.
glabra and C. ovalis is particularly difficult [32], and many
taxonomists prefer to treat these sympatric taxa as a complex [51].  A
few authorities delineate red hickory as a separate species, C. ovalis
(Wang.) Sarg. [10].  Principal differences are in the morphology of
husks or fruit; distinctions between the two entities become apparent
only during the fall [51,55].  Many intermediates have been reported;
some authorities treat C. ovalis as an interspecific hybrid between C.
glabra and C. ovata [32,51].

C. leiodermis Sarg., swamp hickory, is now placed in synonymy with C.
glabra [51].  Pignut hickory hybridizes with butternut hickory (C.
cordiformis) [54].  Demaree hickory, C. X demareei Palmer, is a hybrid
product of pignut hickory and butternut hickory.
