It has fibrous, rough grey or yellowish grey-brown or orange-brown-grey coloured bark throughout. It is attached to the trunk in flat strips resembling a typical stringybark.

It flowers between July and October producing axillary unbranched inflorescences but can appear to be arranged in clusters toward the end of the branch. The ovoid to obovoid shaped green to yellow mature buds are {{convert|0.7|to|0.8|cm|in|3|abbr=on}} in length and {{convert|0.3|to|0.4|cm|in|3|abbr=on}} wide and have creamy shaped flowers.[2] The fruit that form after flowering have a truncate-globose to hemispherical shape with a length of {{convert|0.5|to|0.8|cm|in|3|abbr=on}} and a width of {{convert|0.5|to|1.0|cm|in|3|abbr=on}}. The disc is almost level and has three or four valves. The fruit contain brown coloured seeds with a pyramidal shape and a length of about {{convert|1.5|to|2.5|mm|in|3|abbr=on}}.[2] TaxonomyThe species was first formally described by the botanists Lawrence Alexander Sidney Johnson and Ken Hill in 1992 as part of the work "A taxonomic revision of the White Mahogonies, Eucalyptus series Acmenoideae (Myrtaceae)" as published in the journal Telopea. The only known synonym is Eucalyptus irritans.[3] The specific epithet is taken from the Latin word mediocris meaning "middling" in reference to medium-sized habit of the tree.[2] E. mediocris is part of the white mahogany group as recognised by Ken Hill, others in the group include; Eucalyptus acmenoides, Eucalyptus apothalassica, Eucalyptus carnea, Eucalyptus helidonica, Eucalyptus latisinensis, Eucalyptus psammitica and Eucalyptus umbra.[4]The type specimen was collected by Ken Hill just north of Glenhaughton in 1996.[5] DistributionThe tree is [native to an area of inland Queensland from around the Carnarvon Range in the north east extending south to the Atherton Tableland.[4] See also
