TAXONOMY:

The fully documented scientific name of shrub live oak is Quercus turbinella Greene (Fagaceae) [32,39,40,91,101]. It is a member of the white oak subgenus Lepidobalanus or Quercus [41,64,77,]. Varieties are as follows [40,91,101]:

Quercus turbinella var. californica (Tucker) L. Benson   California shrub live oak
Quercus turbinella var. turbinella   shrub live oak

Shrub live oak hybridizes with Gambel oak (Q. gambelii): The hybrid is described as Q. × pauciloba Rydb. [49]. Shrub live oak-Gambel oak hybrids are particularly evident in northern and southwestern Utah and in central Colorado [13,14,21,91,92,93]. Alvord oak (Q. × alvordiana Eastw.) results from hybridization of shrub live oak and blue oak (Q. douglasii) [49]. Shrub live oak also hybridizes with sand shinnery oak (Q. havardii), Nuttall's scrub oak (Q. dumosa), gray oak (Q. grisea), and valley oak (Q. lobata) [14,30,49,67,92,93,99,102].

Welsh [99] divided Utah oaks into 3 complexes, one of which he identified as the shrub live oak (Quercus turbinella) complex. According to Welsh [99], there are "no apparent barriers to hybridization and intermediates are known between nearly all (species)" within the complex.
