The flowers are sessile. The calyx has five lobes (2.5–3 mm long), which are covered in dendritic hairs, and the mauve, purple, lilac or violet corolla is 4–9 mm long, with no dots or stripes in its throat. There are five stamens. It generally flowers in spring and summer.

In New South Wales it is found in arid and semi-arid areas on sandy soils in spinifex communities and low shrublands.
