TAXONOMY : 
The currently accepted scientific name of interior live oak is Quercus
wislizenii A. DC [5].  Interior live oak is a member of the black or red
oak subgenus Erythrobalanus [2,7].  It readily hybridizes with other
sympatric oaks including California black oak (Q. kellogii) and
California live oak (Q. agrifolia) [2,3,4,10].  The oracle oak (Q. x
morehus) is believed to be a product of interior live oak and California
black oak hybridization [9,10].

Interior live oak is described as morphologically "diverse," and a
number of recognizable varieties or forms have been reported [9].  These
taxa differ in such characteristics as leaf and acorn morphology, and
general growth habit.  Currently recognized varieties are as follows
[3,5,6]:

          Quercus wislizenii var. frutescens Engelm.
          Quercus wislizenii var. wislizenii
          Quercus wislizenii forma extima Jeps.
