TAXONOMY : 
The currently accepted scientific name of post oak is Quercus stellata
Wangenh. [30,47].  Post oak has been placed within the subgenus
Lepidobalanus, or white oak group [59].

The following three varieties are recognized [30]:

         Q. s. var. stellata
         Q. s. var. margaretta (Ashe) Sarg. (sand post oak)
         Q. s. var. paludosa Sarg. (Delta post oak)

Identification of post oak is difficult because of its many growth
forms.  At times, local populations have been given species or varietal
status.  A rhizomatous dwarf post oak that grows near Lufkin, Texas, is
called Boynton post oak (Q. boyntonii).  Drummond post oak, which grows
in deep sands of Texas, is thought to be a hybrid between post oak and
sand post oak [46].  It has also been considered a species (Q.
drummondii) by some authors [13,46].

Post oak hybridizes with the following species [30]:

  x Q. alba (white oak):  Q. X fernowii Trel.
  x Q. bicolor (swamp white oak):  Q. X substellata Trel.
  x Q. durandii (Durand oak):  Q. X macnabiana Sudw.
  x Q. havardii (Havard oak)
  x Q. lyrata (overcup oak):  Q. X sterrettii Trel.
  x Q. macrocarpa (bur oak):  Q. X guadalupensis Sarg.
  x Q. minima (dwarf live oak):  Q. X neo-tharpii A. Camus
  x Q. mohriana (Mohr oak)
  x Q. prinoides (dwarf chinkapin oak):  Q. X stelloides Palmer
  x Q. prinus (chestnut oak):  Q. X bernardiensis W. Wolf
  x Q. virginiana (live oak):  Q. X harbisonii Sarg.
