|E. moluccana, field distribution|
Eucalyptus moluccana, commonly known as the grey box or gum-topped box, is a medium-sized to occasionally tall tree with rough, persistent bark on the lower trunk, shedding above to leave a smooth whitish or light grey, sometimes shiny surface; hence the original name Eucalyptus hemiphloia, from the Ancient Greek hemi- "half", -phloia or phloos "bark".
The adult leaves are stalked, broad lanceolate to lanceolate, to 14 x 3.5 cm in length, glossy, green, flat or undulate, with numerous oil glands.
The white flowers appear in mid summer to mid autumn.
Distribution is widespread on the coastal plains and ranges northwards from Jervis Bay in New South Wales to the area between Rockhampton and Mackay in Queensland, then with a substantial gap to the northern occurrences in the ranges from west of Paluma to the southern part of the Atherton Tableland; also two small disjunct patches east of Clermont near Eungella Dam.
