Adult leaves are elliptical to {{convert|9|cm|in|1}} in length and {{convert|2.5|cm|in|2|abbr=on}} wide concolorous, glossy, light green.[3] Yellow-green flowers appear from late winter to late spring between August and November.[5] The axillary inflorescences are on unbranched strap-like peduncles that are around {{convert|7|cm|in|1|abbr=on}} long. Each inflorescence has between seven and twenty flowers. That buds are sessile with a fused hypanthia. The buds have a length of about {{convert|5.5|cm|in|1|abbr=on}} with a diameter of about {{convert|2|cm|in|2|abbr=on}}, are scarred and have a horn-shaped operculum. The fruits that form later have an ascending disc and three strongly exserted valves. They contain blackish brown seeds with a flattened-ovoid to cuboid shape.[6] TaxonomyThe species was first formally described by the botanists Denis John Carr and Stella Grace Maisie Carr in 1981 as part of the work The Lehmannianae: a natural group of Western Australian eucalypts as published in the Australian Journal of Botany.[4] The type specimen was collected by Alex George in 1970.[5] E. conferruminata belongs in Eucalyptus subgenus Symphyomyrtus section Bisectae subsection Hadrotes because the coarsely bisected cotyledons, erect stamens and larger thick rimmed fruits. The subsection Hadrotes contains ten species of which eight do not have oil glands in the branchlet pith. Together these eight species form series Lehmannianae, a group that have fruit with exserted valves that have fused tips even after the seeds are lost, a feature also shared with the distantly related Eucalyptus cornuta.[9]Of the eight species in series Lehmannianae four species; E. conferruminata, E. lehmannii, E. mcquoidii and E. arborella all have the buds in each an axillary cluster that is fused basally.[6] DistributionNative distribution is limited to the south of Western Australia, from Two Peoples Bay east to beyond Esperance, including islands in the Archipelago of the Recherche. Always coastal often on massive granite rocks.[7] It is often found on hillsides and in gullies growing in sandy-loamy soils over granite or quartzite.[2] The species has become naturalised in the Southwest region of Western Australia, via revegetation projects, windbreaks, and as a garden escapee.[2] E. conferruminata has a limited distribution in Victoria where it has become sparingly established in the Gippsland Plain and Wimmera areas after having spread by see dispersal from planted trees.[8] The species, once sold as Eucalyptus lehmannii, has also become naturalised in California.[9] CultivationThe plant is sold commercially as an ornamental, wind break or for erosion control. It will tolerate drought once established, moderate frost and grows in a variety of soil types including waterlogged soils.[1] See also{{Portal|Trees}}
