Eucalyptus moluccana, commonly known as the grey box, gum-topped box[3] or terriyergro,[4] is a medium-sized to tall tree with rough bark on part or all of the trunk, smooth bark above, lance-shaped adult leaves, flower buds usually in groups of seven, white flowers and cup-shaped to barrel-shaped fruit.

Eucalyptus moluccana is a tree that typically grows to a height of 30 m (98 ft) and forms a lignotuber.

[3][4][5][6] Eucalyptus moluccana was first formally described in 1832 by William Roxburgh in his Flora Indica; or descriptions of Indian Plants.

[4] Grey box 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.

Further north there is a substantial gap, with occurrences in the ranges from west of Paluma to the southern part of the Atherton Tableland and two small disjunct patches east of Clermont near Eungella Dam.
