About
Eucalyptus deanei, commonly known as mountain blue gum, round-leaved gum, or Deane's gum, is a species of large tree endemic to New South Wales. It has smooth bark, lance-shaped leaves that are paler on the lower surface, flower buds in groups of seven to eleven, white flowers and cup-shaped to bell-shaped fruit.
Where it grows
Eucalyptus deanei is found in two disjunct populations. The southern range is from Thirlmere to Broke, near Singleton, while the northern range is from Armidale on the Northern Tablelands through to the D'aguilar Range west of Brisbane. It is a dominant tree of tall forests in sheltered valleys where there is plenty of moisture, on clay or loam soils, and alluvial sands, although it sometimes grows on more elevated areas. They are most famously seen at the Blue Gum Forest in the Grose Valley within the Blue Mountains National Park.
