Scientific name: Eucalyptus pumila
Conservation status in NSW: Vulnerable
Commonwealth status: Vulnerable
Profile last updated: 01 Dec 2017


A mallee-form eucalypt to 6 m high with smooth bark that sheds completely from stems in strips; bark coppery in colour, but weathering to greyish. Juvenile leaves are ovate, up to 12 cm long and 6 cm wide. Adult leaves are lanceolate to falcate, up to 16 cm long and 2.5 cm wide, glossy green both sides. Inflorescences (groups of flowers, buds or fruits) form in angle between the stem and leaf and are 7-flowered. Buds are stalked, up to 12 mm long and 9 mm in diameter. Flowers are white. Fruit are hemispherical, with a short stalk, 6 – 7 mm long and 7 – 9 mm in diameter, with four exerted valves.


Currently known only from a single population west of Pokolbin in the Hunter Valley. Historical records also exist for Wyong and Sandy Hollow, however, has not been recorded recently in these areas.

Habitat and ecology

  • The single known population occupies north-west-facing slopes derived from sandstone.
  • Present as a mid-canopy species to a height of 6 m within dry sclerophyll woodland which has a canopy comprising Eucalyptus fibrosa, Callitris endlicheri and, to a lesser extent, Corymbia maculata.
  • Very little is known about the biology or ecology of this species.
  • It is thought to flower in April-May, but like many eucalypts does not flower every year.
  • Individual plants are understood to regrow by sprouting from a basal lignotuber and therefore can persist following fires. However, such vegetative reproduction may suppress the production of fruits/seeds, necessary for the recruitment of new individuals to a population, and the time between such disturbance and the onset of sexual reproduction is not known.
