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.

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).
