Description

Rainforest tree to 20 metres tall. Leaves opposite, coarsely toothed, roughly oval in shape, 6 to 12 cm long, 1.5 to 6 cm wide, with a raised mid-vein on the upper surface. Small, pale greenish white flowers (rarely with a pink margin), borne in a many-flowered panicle from the leaf base.

Distribution

Restricted to the Illawarra region where it has been recorded from the local government areas of Shoalhaven, Kiama, Shellharbour and Wollongong.

Habitat and ecology

  • Occupies the rocky hillsides and gullies of the Illawarra lowlands, occasionally extending onto the upper escarpment slopes.
  • Associated vegetation includes rainforest and moist eucalypt forest.
  • Associated soils are loams and clay loams derived from volcanic and fertile sedimentary rocks.
  • Flowers briefly in September and early October with fruits taking 10 to 12 months to mature.
  • Capable of vegetative reproduction from stems (coppicing) and rhizomes (suckering).
  • Low levels of seed production are suspected, with stems at most sites appearing to only produce ‘pseudo-fruit’ which lack seeds.
  • Possibly killed by fire.
