A shrub or small tree to about 20 ft, of graceful habit, with slender, angled branchlets. Phyllodes set densely on the stem, 1⁄4 to 1⁄2 in. long and wide, triangular-obovate or unequally four-angled; venation prominent. Flower-heads rich yellow, globular, only 1⁄6 in. or so wide, arranged in long compound racemes. Flowering time March to April.
Native of Victoria and New South Wales. There is a good example of this acacia at Ilnacullin (Garinish Island), Co. Cork, about 24 ft high. At Malahide Castle, near Dublin, it proved hardy in the winters of 1961–3 and is now some 12 ft high on a garden wall. It is remarkable for its very lop-sided phyllodes, set edgeways to the shoot.
Although not reliably hardy near London, this species is fast-growing, flowers when young, and sets good seed. In Mr R. C. Barnard’s garden at Bovey Tracey, Devon, some plants even survived the very cold winter of 1962–3. He suggests that this species may vary in hardiness (The Garden (Journ. R.H.S.), Vol. 103 (1978), p. 294).
An allied species, distinguished by its silvery-grey, triangular phyllodes. It is probably very tender, but according to Thurston was once grown out-of-doors at St Michael’s Mount. Native of New South Wales and Queensland. Bot. Mag., n.s., t. 322.
