It is the dominant oak in many areas on Catalina Island.It was described as a new species in 1994 from a specimen on Santa Cruz Island.This is a shrub or a small tree growing up to five meters in height, or occasionally taller. The leaves are roughly oval in shape and edged with pointed teeth. The green blades are up to 4 centimeters long by 4 wide. They have shiny upper surfaces and waxy, hairy, glandular undersides.
