Scientific name: Eucalyptus copulans
Conservation status in NSW: Endangered
Commonwealth status: Endangered
Profile last updated: 20 Oct 2020


An often multi-trunked tree to 10 m tall, with smooth, grey-green bark, shedding in ribbons. Juvenile leaves are a dull grey-green and narrow. Adult leaves are 6-12 cm long, 1-1.8 cm wide and have a ‘satiny’ sheen. Fruit is round and 4-6 mm long. E. copulans is not considered to be a distinct species, but rather a hybrid between E. stellulata and E. moorei. E. copulans is intermediate in many characteristics between these two species.


No original trees remain extant. Three additional specimens have been planted in Council Reserve along Jamison Creek at Wentworth Falls in the Blue Mountains, NSW. These were propagated from the last extant tree. A larger population is thought to have occurred historically in the locality. 

Habitat and ecology

  • Due to the low number of records, the habitat requirements of this species are poorly known, but it is assumed that it occurred in the swampy areas adjacent to Jamison Creek around Wentworth Falls. Much of this habitat has been cleared for development, however some habitat south of the Great Western Highway has been retained as recreation reserve.
  • Associated species at the sites where this species is found include Eucalyptus radiata, E. parramatensis, E. stricta, Grevillea acanthifolia, Hakea dactyloides, Gleichenia dicarpa, Leptospermum juniperinum, L. flavescens, Todea barbara and Petrophile pulchella.
  • The white flowers occur in summer/autumn and mature fruit have been collected in May. The seed capsules collected from this species appear to have very few seeds per capsule, and the seed does not appear to have a high viability.
  • The role that fire plays in the ecology of E. copulans is not known.
