Eucalyptus planchoniana, commonly known as the needlebark stringybark or bastard tallowwood[1] is a species of small to medium-sized tree that is endemic to eastern Australia. It has rough, stringy bark on the trunk and larger branches, lance-shaped to curved adult leaves, flower buds in groups of seven, white flowers and cup-shaped, cylindrical or barrel-shaped fruit.
Eucalyptus planchoniana is a tree that typically grows to a height of and forms a lignotuber. It has rough, reddish, often prickly, stringy bark on the trunk and larger branches. Young plants and coppice regrowth have elliptical to lance-shaped or curved, bluish green leaves that are long and wide and petiolate. Adult leaves are the same shade of green or bluish green on both sides, lance-shaped to curved, long and wide on a petiole long. The flower buds are arranged in leaf axils on an unbranched, flattened peduncle wide, the individual buds on pedicels long. Mature buds are oval to spindle-shaped or diamond-shaped, long and wide with a conical to beaked operculum. Flowering occurs from October to December and the flowers are white. The fruit is a woody, cup-shaped, cylindrical or barrel-shaped capsule long and wide with the valves below rim level.[2] [3]
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.[4] [5] The specific epithet honours Jules Emile Planchon.
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.
