The concolorous, dull, blue-green to green adult leaves are arranged alternately. The leaf blade has a lanceolate shape with a length of {{convert|5|to|13|cm|in|1}} and a width of {{convert|0.8|to|2.5|cm|in|2|abbr=on}} with a that tapers to the petiole.[2] It blooms between September and July producing cream-yellow flowers.[1] Each unbranched axillary inflorescence usually has more than seven pedicellate buds. The mature buds have an ovoid to oblong shape with a length of {{convert|1.4|to|2.1|cm|in|2|abbr=on}} and a width of {{convert|0.5|to|0.6|cm|in|3|abbr=on}}. The buds are scarred with a beaked to horn shaped operculum and pale yellow flowers. After flowering erect to pendulous fruits form that are mostly urn shaped with a length of {{convert|0.6|to|1.0|cm|in|3|abbr=on}} and a width of {{convert|0.5|to|0.8|cm|in|2|abbr=on}}. The fruits have a descending disc with three or four exserted valves. The brown-grey seeds within the fruit have an ovoid or flattened-ovoid shape.[2] TaxonomyThe species was first formally described by the botanists Lawrence Alexander Sidney Johnson and Ken Hill in 1999 as part of the work Systematic studies in the Eucalypts. A review of series Sociales (Eucalyptus subgenus Symphyomyrtus, Section Bisectaria, Myrtaceae) as published in the journal Telopea. Known synonyms include; Eucalyptus inconstans, Eucalyptus diemalensis, Eucalyptus semivestita, Eucalyptus dasyphloia and Eucalyptus transcontinentalis subsp. semivestita.[3] The specific epithet is taken from the Latin word moderatus meaning moderate in reference to the medium sized habit and leaves, buds and fruit of the plant compared to its closest relatives.[2] DistributionIt is found on flats, slopes and road verges in the eastern Wheatbelt and the Goldfields-Esperance region growing in sandy-loamy soils over granite or laterite.[1] The species is associated with the western mallee subgroup which is characterised by several eucalypts including Eucalyptus oleosa, Eucalyptus eremophila, Eucalyptus incrassata, Eucalyptus foecunda, Eucalyptus redunca and Eucalyptus uncinata. The understorey is predominantly shrubby with species of Melaleuca and Acacia along with the occasional Triodia.[4] See also{{Portal|Trees}}
