In Australia the Acacias are typically called
wattles. This one is widely naturalized in most Australian states, but
is native to the Cootamundra region of New South Wales. It occurs in
California along roadsides and in disturbed areas to an elevation of
about 1000'. It belongs to the mimosa subfamily of the Fabaceae. It
is a tree reaching 20' or so in height with unarmed branches. The silvery-blue
leaves are 2-pinnate, the primary leaves with 3-6 pairs of overlapping
leaflets, and the secondary leaflets with 12-20 pairs of linear and
touching leaflets. The inflorescence is an axillary raceme of 8-10 bright
yellow flower heads. The ± straight brown fruits are narrowed
between seeds and are 1-1/2" to 4" in length.
