angustifolia Domin Melaleuca citrolens, commonly known as gulbarn,[2] is a plant in the myrtle family, Myrtaceae and is endemic to northern Queensland and the north-eastern part of the Northern Territory.

Plants in this species were originally included in Melaleuca acacioides until a review of the genus in 1986.

[3] Melaleuca citrolens is a tree growing up to 10 m (30 ft) tall with grey or white papery bark.

[4][5] Melaleuca citrolens was first formally described in 1986 by Bryan Barlow in Brunonia as a new species.

[6] The specific epithet (citrolens) refers to the Rutaceae genus Citrus (which includes the orange and lemon) and to the Latin word olens meaning "smelling" or "odorous", apparently referring to the aromatic foliage.
