Quillaja saponaria branchlet. John Rawlings, 2006

A small evergreen tree with small glossy dark green leaves, some of them with a few teeth; easily mistaken for a young live oak at a quick glance. The flower is white, ½-inch across, hairy, and with five petals; fruit consists of 5 leathery follicles.

There are two specimens at the sides of the Center of Turbulence Research, 481 Panama Mall (across the street from the Old Union). A 2005 specimen is thriving on Serra Street, planted between the sidewalk and the road, about 30 yards north of the driveway to the Recycling Center. Other examples can be seen in Palo Alto at 318 Ferne Avenue (left of driveway) and across the street at 323 Ferne (left of the hydrant).
