Chaenostoma revolutum is a perennial shrublet growing to 60 cm in height with a branching, erect to spreading habit. The leaves are grey-green, opposite and narrow with their margins usually rolled under. There are tiny glandular hairs on the leaves. Several Chaenostoma shrubs are known as skunkbushes, due to their fetid smell. This one is the fineleaf skunkbush, suggesting a well below pleasant odour.
The flowers are small, mauve-blue or pink with orange throats from which yellow anthers protrude. The flower tube of Chaenostoma revolutum is 1 cm or shorter. The five petals have rounded tips.
The genus name refers to the gaping or funnel-shaped flower tube found on the plants (chaeno meaning to gape or open in Greek; stoma means mouth, also in Greek) (Vlok and Schutte-Vlok, 2010; Bond and Goldblatt, 1984).
