Eucalyptus platyphylla, commonly known as poplar gum or white gum,[1] is a species of medium-sized tree that is endemic to Queensland. It has smooth. powdery bark, heart-shaped, egg-shaped to almost round leaves, flower buds in groups of seven, white flowers and conical to hemispherical fruit.
Eucalyptus platyphylla is a tree that typically grows to a height of and forms a lignotuber. It has smooth, powdery, pale pink to greenish white bark. Young plants and coppice regrowth have deltoid leaves that are long and wide. Adult leaves are the same shade of dull greyish green on both sides, heart-shaped to egg-shaped or almost round, long and wide on a petiole long. The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle long, the individual buds sessile or on pedicels up to long. Mature buds are oval to almost spherical, long and wide with a rounded to conical operculum. Flowering occurs from June to October and the flowers are white. The fruit is a woody, conical to hemispherical capsule long and wide with the valves near rim level or slightly protruding.[2]
Eucalyptus platyphylla was first formally described in 1859 by Ferdinand von Mueller in Journal of the Proceedings of the Linnean Society, Botany from material collected near the Burdekin River.[3] [4] The specific epithet (playtphylla) is from ancient Greek words meaning "flat", "wide" or "broad" and "-leaved", referring to the broad leaves.
Poplar gum is mostly found within of the coast in soils that often remain west for long periods. It occurs from Horn Island in the Torres Strait to near Rockhampton.
This eucalypt is listed as "least concern" under the Queensland Government Nature Conservation Act 1992.[5]
