Eucalyptus × chrysantha is a mallee that is endemic to Western Australia. It is a putative hybrid between E. preissiana and E. sepulcralis and has lance-shaped to curved adult leaves, flower buds in groups of between three and six, white to yellow flowers and cylindrical to urn-shaped fruit.
Eucalyptus × chrysantha is an erect mallee that typically grows to a height of and has rigid, angular branches. The adult leaves are oblong to lance-shaped or curved, dark green on both sides, long and wide, tapering to a flattened petiole long. The flower buds are arranged in groups of between three and six in leaf axils on a peduncle long. Mature buds are about long and wide with a conical operculum long. Flowering occurs between August and December and the flowers are white to yellow. The fruit is a woody, oval to cylindrical or urn-shaped capsule long and wide.[1]
This eucalypt was first formally described in 1938 by William Blakely and Henry Steedman who gave it the name Eucalyptus chrysantha and published the description in Journal and Proceedings of the Linnean Society of New South Wales. It is a presumed hybrid between E. preissiana and E. sepulcralis.[2] [3] The specific epithet (chrysantha) is derived from the Ancient Greek words chrysos meaning "gold"[4] and anthos meaning "flower".
Eucalyptus × chrysantha grows on flats and around rocky outcrops in the Fitzgerald River National Park.
This mallee is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife, meaning that it is poorly known and from only one or a few locations.[5]
