The flowers of Erepsia polita grow solitary at stem-tips. There are five, fleshy, leaf-like sepals and the stalks are short.
The pale to dark pink or purple-pink petals spread in a few whorls around the flower centre. There is a small, pale or reddish ring of discolouring at the petal bases. The flower centre is cream from numerous stamens and staminodes. Erepsia staminodes usually conceal the stamens at least partly, but not very effectively or systematically in this photo of an ageing flower.
Flowering happens in spring according to the observations published in iNaturalist (Vlok and Schutte-Vlok, 2015; Bond and Goldblatt, 1984; iNaturalist).
