Description

A low spreading shrub to 30 cm high. It has few to many weak, twisted stems and branches, covered with long shaggy hairs when young, becoming more densely hairy with longer hairs wearing off. Leaves are usually linear, 7.5 - 10 mm long. Flowers are yellow, terminal on main branches.

Distribution

Occurs from Baulkham Hills to South Maroota in the northern outskirts of Sydney, where there are currently 16 known sites, and at one locality at Mount Boss, inland from Kempsey. No populations are known from a formal conservation reserve.

Habitat and ecology

  • Flowering time is July to December. The species occurs on sandstone ridgetops often near the shale/sandstone boundary.
  • Occurs in both open woodland and heathland, and appears to prefer open disturbed areas, such as tracksides.
  • The fruit is dehiscent and the seed has a fleshy aril which attracts ants and encourages them to disperse the seeds. The soil seedbank is persistent.
  • Highly sensitive to both frequent and infrequent fire and other disturbance regimes. The recommended minimum fire interval is unknown, however the recommended maximum fire interval is 25 years.
  • An obligate seeder, it is usually killed by fire, sometimes resprouting from the base. Flowers first appear from resprouting material about 2 years after fire.
