The Quercus Arizonica is commonly known as the Arizona Oak as well as Arizona White Oak.
The currently accepted scientific name of Arizona white oak is Quercus arizonica Sarg. It is a member of the oak family (Fagaceae) . No infrataxa are recognized. Where distributions overlap, Arizona white oak hybridizes with gray oak (Q. grisea), Gambel oak (Q. gambelii), and Mohr shin oak (Q. mohriana) .Arizona white oak is distributed from central Arizona to southwestern New Mexico . Scattered populations occur in western Texas and northern Mexico. In Mexico, the range of Arizona white oak extends from the state of Coahuila westward to Baja California Sur . It occurs in fewer than 20 locations in Baja California Sur and is a species of concern in Mexico .Arizona white oak is found in diverse communities along elevation or moisture gradients from savannas, semidesert grasslands, and interior chaparral to Madrean evergreen woodland and pine-oak (Pinus spp.-Quercus spp.) communities . Arizona white oak is codominant with Emory oak (Q. emoryi) and gray oak in the encinal mixed woodland series and Madrean evergreen woodland series . Arizona white oak habitat series occur in savannas of New Mexico . Arizona white oak is an indicator species in dry Douglas-fir (Pseudotsuga menziesii), Chihuahua pine (Pinus leiophylla var. chihuahuana), ponderosa pine (P. ponderosa), and Apache pine (P. engelmanii) habitat and community types . Arizona white oak is dominant or codominant in open and closed-canopy pinyon-juniper (Juniperus spp.) woodlands . Occasionally, Arizona white oak is an important understory species in pinyon-juniper stands and Mexican pinyon (P. cembroides) forests . Isolated Arizona white oak occur infrequently in riparian woodland associations, such as Arizona walnut (Juglans major) and Arizona sycamore (Platanus wrightii) community types with permanent or semipermanent streams . Arizona white oak occurs on edges of interior chaparral of Arizona in communities such as the Arizona white oak-yellowleaf silktassel (Garrya flavescens)-Emory oak association . Some of the publications in which Arizona white oak is listed as a dominant or indicator species are: (1) Forest and woodland habitat types (plant associations) of Arizona south of the Mogollon Rim and southwestern New Mexico (2) Forest habitat types south of the Mogollon Rim, Arizona and New Mexico (3) Classification of mixed broadleaf riparian forest in Tonto National Forest (4) A series vegetation classification for Region 3 (5) A forest habitat type classification of southern Arizona and its relationship to forests of the Sierra Madre Occidental of Mexico (6) Vegetation of the Santa Catalina Mountains, Arizona: a gradient analysis of the south slope . Woody species associated with Arizona white oak but not previously mentioned in Distribution and Occurrence information include Arizona madrone (Arbutus arizonica), Arizona rosewood (Vaquelina californica), and coral-bean (Erythrina flabeliformis) .Some of the information provided here is attributed to:Pavek, Diane S. 1994.
