The dull green leaves are narrow elliptic or linear shaped, 4–20 mm (0.16–0.79 in) long and 20–40 mm (0.79–1.57 in) wide, flattened, glandular hairs on the upper surface, toothed edges and almost sessile. The bright blue or rarely white flowers 10–12 mm (0.39–0.47 in) in diameter, usually singly or up to 3 in a cluster in a terminal inflorescence on a pedicel 2–10 mm (0.079–0.394 in) long, calyx 3–4 mm (0.12–0.16 in) long, lobes narrow-triangular or lance-shaped, equal in size. It mostly flowers in summer or sporadically throughout the year. The fruit is a brown drupe containing one or two seed.[2][3][4]
Rough halgania occurs in a wide range of situations including sandy loam, sand plains, mallee and sand dunes in Western Australia, South Australia, Victoria and the Northern Territory, but is restricted to mallee communities in New South Wales.[8][9]
