Description
Eucalyptus alatissima is a multi-stemmed mallee, or occasionally a single-stemmed tree and typically grows to a height of Шаблон:Convert. It has smooth, tan to cream bark on the upper parts and rough grey fibrous to ribbon-like bark toward the base.

Both the flower cup and operculum have a powdery covering and have prominent longitudinal wings, the operculum longer than the flower cup. It blooms between July and October producing inflorescences with pink to red or rarely yellow flowers. The fruit are woody capsulesШаблон:Convert long and Шаблон:Convert wide with prominent longitudinally winged ridges.

Taxonomy
This eucalypt was first formally described in 1993 as Eucalyptus kingsmillii subsp. alatissima by the botanists Ian Brooker and Stephen Hopper in the journal Nuytsia.[5][6] In 2013 it was raised to species status by Dean Nicolle in his book Native eucalypts of South Australia.[7] The name of the species is commonly misapplied to Eucalyptus kingsmillii and Eucalyptus pachyphylla.[8] The specific epithet (alatissima) is the superlative form of the Latin word alatus meaning winged,[9]Шаблон:Rp hence "most winged" or "very much so",[9]Шаблон:Rp referring to the prominently winged buds and fruit.[1][2]
Distribution and habitat
This mallee grows in gravelly red sands and loam in mallee vegetation or mulga scrub near the South Australia-Western Australia border. It is found in central parts of the Great Victoria Desert between Vokes Hill in South Australia and Neale Junction east of Laverton in Western Australia. Its range includes parts of the Goldfields region.[1][3]
Conservation
Eucalyptus alatissima is classified as "not threatened" in Western Australia by the Western Australian Government Department of Parks and Wildlife.[3]
