Description

Shrub to 50 cm high, with a stout rootstock. It has narrow leaves (1 to 4 cm long, 1 to 4 mm wide) with a rib down the middle of the leaf. The flowers are pea-like, yellow with a red centre, and are borne in loose clusters at the ends of branches.

Distribution

This endangered population has been recorded from between Austinmer and Albion Park in the local government areas of Wollongong and Shellharbour.

Habitat and ecology

  • All known sites (excluding the site at Austinmer) occupy woodland or forest dominated by Forest Red Gum (Eucalyptus tereticornis) and/or Woollybutt (E. longifolia).
  • At Austinmer, the species is recorded from a coastal headland.
  • Flowering period is August to January, with seeds maturing from November.
  • The species is difficult to locate when not in flower, as it is often tangled amongst (and partially concealed by) a grassy understorey.
  • The response of the species to fire is reportedly variable. Some plants have been observed to reshoot following fire while others have been killed.
  • A soil seedbank for the species exists although the longevity of this seedbank is not known.
