A shapely tree with silvery foliage and masses of brilliant golden flowers in baileyana late winter. It can be separated from green wattle and silver wattle by having four (occasionally five) pairs of pinnae (the major segments into which the leaf is divided). Each pinna is further subdivided into many tiny silvery flat pinnules about ¼ inch long. Just below the point of attachment of each pair of pinnae there is a gland with a dark spot that is visible from the upper surface of the pinnae.
This small tree is a candidate, with Cassia eremophila, for first prize among yellow-flowered trees. See it at 880 Lathrop Drive. Three are south of The Knoll behind the west-most of two trailer annexes, several more are near the intersection of Escondido Road and Blackwelder Court, and a single tree is on the southwest side of Lake Lagunita (located on map).
Name derivation: Acacia – Greek akis, a sharp point; baileyana – after A.M. Bailey (1827–1915), Australian botanist.
