The flower of Monsonia spinosa is pale to bright yellow as a common name of the plant, yellow bushman candle, indicates. Pollen grains are amply strewn in the base of the corolla cup in picture, fallen from the ripe anthers.
The five-pointed, short-branched stigma has become brownish in the photo, attended to by fluff-headed acolytes, the surrounding stamens. The dark veins upon the petal surfaces are sparsely branched.
Flowering happens from late winter to early spring (Le Roux, et al, 2005; iNaturalist).
