Eucalyptus scyphocalyx

Eucalyptus scyphocalyx, commonly known as goblet mallee, is a species of mallee that is endemic to southern areas of Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of three or seven, creamy white flowers and cup-shaped to cylindrical fruit.
Description.
"Eucalyptus scyphocalyx" is a mallee that typically grows to a height of and forms a lignotuber. It has smooth pale brown and grey bark, although larger specimens often have a stocking of rough, ribbony bark near the base. Young plants and coppice regrowth have dull green, lance-shaped leaves that are long and wide. Adult leaves are the same shade of green on both sides, lance-shaped, long and wide, the base tapering to a petiole long. The flower buds are arranged in leaf axils in groups of three or seven on an unbranched peduncle long, the individual buds on pedicels long. Mature buds are cylindrical to spindle-shaped, long and wide with a hemispherical to conical operculum. Flowering mainly occurs from July or September to December and the flowers are creamy white. The fruit is a woody cup-shaped to cylindrical capsule long and wide with the valves below rim level.
Taxonomy and naming.
The goblet mallet was first formally described in 1867 by George Bentham from an unpublished description by Ferdinand von Mueller. Bentham published the description in "Flora Australiensis" and the plant was given the name "Eucalyptus dumosa" var. "scyphocalyx". In 1929, Joseph Maiden and William Blakely raised the variety to species status as "E. scyphocalyx", publishing the change in Maiden's book "A Critical Revision of the Genus Eucalyptus". The specific epithet ("scyphocalyx") is from the ancient Greek word "scyphos", referring to the cup-like calyx.
In 2001, Lawrie Johnson and Donald Blaxell described two subspecies of "E. scyphocalyx" in the journal "Telopea" and the names have been accepted by the Australian Plant Census:
Distribution and habitat.
"Eucalyptus scyphocalyx" is found on sand plains between Jerramungup, Ravensthorpe and Salmon Gums in the Great Southern and Goldfields-Esperance regions. Subspecies "triadica" has a more restricted distribution in an area northeast of Esperance.
Conservation status.
This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
