Eucalyptus crebra
narrow-leaved ironbark

Myrtaceae (myrtle family)

Eucalyptus crebra. Matt Ritter

Three mature trees are not far from the Palm Drive sidewalk under the canopy of the great Torrey pine northwest of the intersection of Palm Drive and Arboretum Road. The one nearest the intersection grows on the street side of the chain and bollard barrier between live oaks. The other two are near irrigation control valve #18. A single tree is at the back of the Hoover Tower facing Green East, planted among a forest of E. sideroxylon.

Three saplings were planted in the Ron Bracewell grove near the vernal pool in the Arboretum off Lasuen on 11 February 2008; started from seed collected June 2006 at Stanford, Palm Drive and Arboretum Road.

Recognize narrow-leaved ironbark by the persistent dark bark, gray-green, concolorous leaves, and tiny buds and fruit, arranged in axilary and terminal panicles. Valves are 3–4 and slightly inserted.
