Brooker & Hopper
It is a mallee eucalyptus that grows 2 to 3 metres (7 to 10 ft) in height. It has a lignotuber and has smooth grey bark throughout. Its juvenile leaves are petiolate and ovate to deltoid while the adult leaves are usually 5.5 to 8 centimetres (2.2 to 3.1 in) long and 1.1 to 1.8 cm (0.43 to 0.71 in) wide. The flower buds occur in unbranched clusters of up to 13 and are elongated with long, conical bud caps and are followed by white flowers. The fruits are barrel shaped and are about 0.5 cm (0.20 in) wide. 
Florabase identifies distribution in the IBRA Regions: Geraldton Sandplains, and the Swan Coastal Plain. With the IBRA Subregions being: Dandaragan Plateau, and the Lesueur Sandplain. It grows on slopes and in breakaway areas in sandy clay soils and in gravel over laterite. Part of woodlands, it can be confused with Eucalyptus pluricaulis, which has bluish green leaves that remain dull and with longer, narrower buds and yellowish flowers. E. abdita differs from Eucalyptus wandoo in its mallee habit.
