Description

The Purple-wood Wattle (formerly Acacia carnei) is a dark green and prickly shrub to small tree, 2 - 4 m tall. Plants have a striking, deep-purple heartwood. The phyllodes (wattle leave) are rigid and needle-like, sharply pointed, four-angled and are 2 - 6.5 cm long and 1 - 3 mm wide. Flower-heads are spherical, golden-yellow in colour and are on hairy stalks 12 - 25 mm long. The pods are hard and woody with a short white downiness, straight to strongly curved and are slightly constricted between seeds. The pods are 3 - 5 cm long and 10 mm wide.

Distribution

Occurs in the far western plains, south from west of Tibooburra to the Menindee area. Also has a limited distribution in SA.

Habitat and ecology

  • Grows in grassland and woodland in red, sandy soil; also found in Mulga communities on sand dunes, level sandy sites and alluvial accumulations along watercourses; recorded from inland semi-arid Acacia and Casuarina shrublands and woodlands.
  • Preferred soils are shallow, calcareous and loamy, and include brown earths, crusty alkaline soils and neutral red duplex soils; confined to red-earth dune soils in Kinchega NP as a dominant or occasionally co-dominant, usually on dune crests or slopes.
  • Associated species include Alectryon oleifolius, Casuarina cristata, C. pauper, Maireana pyramidata, Eucalyptus socialis and Enchyleana tomentosa.
  • A long-lived perennial that flowers at any time of year; rarely sets seed but produces new suckers, independent of root disturbance, either annually or biannually in two growth pulses in autumn and spring (during average or above average rainfall years).
  • Tends to occur in colonies of 20 to 60 plants, which are clonal; seed viability is generally low and the majority of seeds are non-dormant when released from the pods, which remain on the parent plant for several years after dehiscence.
  • Observed as common in gregarious groupings on sandhills and ridges; populations in Kinchega NP grow in tall shrublands, comprising a mixture of ramets from a limited number of genetically distinct individuals, with isolated populations likely to be genetically distinct.
