Eucalyptus planchoniana, commonly known as the needlebark stringybark or bastard tallowwood[2] is a species of small to medium-sized tree that is endemic to eastern Australia.

Eucalyptus planchoniana is a tree that typically grows to a height of 20–25 m (66–82 ft) and forms a lignotuber.

It has rough, reddish, often prickly, stringy bark on the trunk and larger branches.

[2][3][4] Eucalyptus planchoniana was first formally described in 1878 by Ferdinand von Mueller in Fragmenta phytographiae Australiae from material collected from near Moreton Bay by Frederick Manson Bailey.

[3] Needlebark stringbark grows in open forest on low ridges and gentle slopes from Moreton Island and Stradbroke Island in Queensland to Camden Haven in coastal New South Wales and as far inland as the Gibraltar Range National Park.
