The fruit is a woody, cup-shaped to hemispherical capsule 6–8 mm (0.24–0.31 in) long and wide with the valves protruding above the rim.

[4][5][6][7] Eucalyptus mooreana was formally described by William Vincent Fitzgerald and the description was published in "The Western Mail" newspaper on 2 June 1906.

[8][9] The specific epithet (mooreana) honours Newton James Moore who was Minister of Lands at the time.

[3][10][11] Eucalyptus mooreana is found on steep rocky slopes and summits in a small area of the Kimberley region of Western Australia where it grows in red sandy soils over sandstone or quartzite in the Wunaamin Miliwundi Ranges.

[4][6][12] In 2008 the species is listed as "vulnerable" under the Australian Federal Government Environment Protection and Biodiversity Conservation Act 1999 and as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Environment and Conservation (Western Australia)[6] meaning that it is likely to become extinct or is rare, or otherwise in need of special protection.
