The flowers are honey-scented and are arranged singly or in groups of up to 3 in leaf axils on glabrous, sticky stalks 7–12 mm (0.3–0.5 in) long.

Flowering occurs in most months and is followed by fruits which are fleshy, pale yellow at first ageing to brownish purple, oval to almost spherical and 4–6.5 mm (0.2–0.3 in) long.

[6] The description was published in Stephan Endlicher's Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel.

[8] The specific epithet is derived from the Latin word desertus meaning "a desert", probably named because the species was collected 'in the arid interior'".

[2] Eremophila deserti is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
