Chrysolepis chrysophylla

Chrysolepis chrysophylla, commonly known as golden chinquapin or giant chinquapin (also spelled chinkapin), is a species of evergreen shrub or tree in the beech family. It is native to California, Oregon and Washington. The species has dark green leathery leaves, with distinct golden-yellow fuzzy undersides and produces small nuts which are protected by conspicuous spiny burs. It may become a large tree on favorable sites, but often remains small and shrubby on exposed, rocky, dry or high elevation places.
