Description

The Carrington Falls Grevillea is a large spreading, prickly shrub to 2.5 m tall and 3 m or more wide. Its stiff leaves are up to 6 cm long and wide and twice-divided, with up to nine narrow, sharp-pointed leaf lobes. The lower surface of the leaf is sometimes obscured by the rolled-back margins but has a prominent midvein when exposed. Drooping clusters of flowers form at the ends of branchlets. The individual flowers all develop on the upper surface of the flower cluster, forming a ‘toothbrush’. The flower tube is purplish cream to mauve-pink and the long style is pale mauve with a green tip. The fruits are up to 10 mm long, hairy with reddish-brown stripes or blotches.

Distribution

The Carrington Falls Grevillea is confined to the Carrington Falls area on the upper Kangaroo River west of Kiama, within Budderoo National Park.

Habitat and ecology

  • The Carrington Falls Grevillea is found mainly on moist creek-sides on sandstone in open heath or eucalypt woodland.
  • It had been regarded as restricted to the water’s edge but the recent discovery of a small population of mature individuals in woodland at least 500m from the water's edge raises doubt about this assumption. The woodland population may represent a rare establishment event although it is more likely that the species was once more widespread in the landscape and has been pushed to the waterside habitat by increased fire in the landscape.
  • Regenerates in abundance from seed after disturbance but seedling mortality is also great and few plants are recruited into the mature population.
