The bark is grey below to grey-brown or red-brown in colour above. The tree blooms between October and November[1] and produces simple axillary conflorescences with seven to eleven flowered umbellasters on peduncles that are narrowly flattened or angular. Buds are glaucous and rostrate or urceolate in shape with a calyptrate calyx that sheds early. Ovoid or urceolate shaped fruits with a depressed disc form later.[2] ClassificationThe species was first formally identified by the botanists Lawrence Alexander Sidney Johnson and Ken Hill in 1999 in the journal Telopea. The type specimen was collected by Ian Brooker and D. Blaxell in 1975 about {{convert|80|km|mi|0}} north east of Kalbarri.[3] It is part of the Eucalyptus subgenus Symphyomyrtus in the section Bisectae and the subsection Destitutae. The tree is similar in appearance to Eucalyptus moderata The species name dolichocera is from the latin words dolio meaning long and chera meaning horn referring to the long and narrow operculum on the buds.[3] DistributionThe species is found in sanddunes, on flats and sandplains and has a range from just north of Geraldton in the Mid West then spreading south down through the Wheatbelt region. It grows in red sand and limestone and laterite soils.[1] See also{{Portal|Trees}}
