Interior live oak (Quercus wislizeni)

Description

It is a large shrub or tree growing to 22 meters (72 feet) tall, although where it is common in the low elevation Sierra foothills it seldom exceeds 10 meters (33 feet). The dark-green leaves - appearing grayish from a distance - are usually small, 2-5 cm (1-2 in) long, thick, and often spiny-toothed at higher elevations, particularly on young trees. The male flowers are on catkins, the female flowers in leaf axils. The acorns are 1-2 cm (0.5-1 in) long, and mature the second season (about 18 months) after flowering.
