Rhus integrifolia · lemonade berry · SW & Baja California
Rhus ovata · sugar bush · SW & Baja California, Arizona

Anacardiaceae (sumac or cashew family)
Rhus integrifolia. From Forest Trees of the Pacific Slope, George B. Sudworth, USDA, 1907

See a fine example in shrub form at the east end of the cycle path between Stanford Avenue and Santa Fe Avenue, and a tree form on the right side of the driveway to the Communication/Networking Services utility building behind Ventura Hall. Specimens of the handsome Rhus ovata, sugar bush, are on the left side of the same driveway with more lemonade berry.

The name lemonade berry refers to a Native American practice of making a lemon-like drink by dissolving a sugary substance found on fresh berries. The dark red wood was referred to as mahogany. The two species hybridize.

It can also be found at the Medical School Office Building, and West Campus Drive near Beckman and Fairchild centers.
