Eucalyptus blaxellii, commonly known as the Howatharra mallee,[1] is a mallee that is native to Western Australia .[2]

The multi-stemmed mallee typically grows to a height of 1 to 4 metres (3 to 13 ft). It blooms between August and November producing cream-white flowers.[2] The bark is smooth with a pinkish-brown or grey over coppery colour. The glossy green lanceolate leaves are narrow and have irregular lateral veins. There are up to seven small buds that are grouped in simple inflorescences. Later these form cup-shaped fruit which have a thin rim and three enclosed valves.[3]

It is found on rocky hillsides and creek flats in the Wheatbelt near Morawa and in the Mid West region between Northampton and Geraldton in the Moresby Range where it grows in sandy-clay soils.[2] The emergent mallee occurs over heath and associated with Eucalyptus loxophleba, Eucalyptus stowardii, Allocasuarina campestris, Melaleuca megacephala, Gastrolobium spinosum and various species of Acacia.[3]

The species was first formally described by the botanists Lawrence Alexander Sidney Johnson and Ken Hill in 1992 in the work Systematic studies in the eucalypts. New taxa and combinations in Eucalyptus (Myrtaceae) in Western Australia. in the journal Telopea.[4]
