Eremophila duttonii is a shrub or small tree growing to a height of between 1 and 3.5 m (3 and 10 ft) with branches that are rough due to old leaf bases, hairy, shiny and sticky due to the presence of resin.
The leaves are arranged alternately along the branches, sometimes clustered near the ends of them and are mostly 30–40 mm (1–2 in) long, 3–5 mm (0.1–0.2 in) wide, linear to lance-shaped, tapering towards the ends and sticky.

The flowers are borne singly in leaf axils on a stalk 10–20 mm (0.4–0.8 in) long.
There are 5 overlapping, sticky, egg-shaped to elliptic sepals which are 10–15 mm (0.4–0.6 in) long.
The petals are 25–35 mm (0.98–1.4 in) long and joined at their lower end to form a tube.
The top of the petal tube is red to orange, fading to yellowish-green below and inside the tube.
Occasionally the petal tube is all yellow.
The tube often has a few short hairs inside and out and is sticky on the outside.
The 4 stamens extend beyond the end of the tube.
Flowering occurs from June to September and is followed by fruits which are dry, oval to cone-shaped with a pointed end and are 7.5–13 mm (0.3–0.5 in) long.
