Description

Shrub to 2.4 m high, root-suckering. Branchlets have a deep, firm covering of dense hairs. Leaves are stiff, broad-linear, 2 – 6 cm long, 0.25 – 0.4 cm wide, with a blunt apex and entire margins which are rolled under so that the leaf is convex, except for the midvein groove, on the upper surface. The upper surface is shiny and smooth or occasionally wrinkled, lower surface covered densely with brownish hairs; petiole 1 – 2 mm long. The flowers are small, 5-petalled, white or cream with mauve anthers. Individual inflorescences (groups of flowers) are up to about 10 cm long, usually with a few ascending branches, few-flowered, with a dense hairy covering.

Habitat and ecology

  • Occurs in dry sclerophyll woodland on sandstone.
  • Flowers in spring.
  • Resprouter from root suckers or basal stem buds after fire.
  • Seed storage and dispersal ecology and germination requirements are unknown. Not enough data to rank sensitivity to either frequent or infrequent fires.
