The flowers of Tritoniopsis antholyza grow in a dense, unbranched, spirally twisted spike. The twisting of the spike is illustrated by the erect buds at the top, as well as the open flowers lower down.
The flowers point outwards in two, more or less opposing arrays. They have narrow, curved tubes that open in a trumpet-shape, up to 3 cm long. The corolla lobes recurve variably. Flower colour is reddish pink or salmon, sometimes with a hint of yellow. There may be dark streaks on the lower tepals.
The stamens are together under the upper tepal. The protruding stigma has three short branches.
Pollination is done by long-proboscid flies, the Table Mountain Beauty butterfly and possibly sunbirds (Curtis-Scott, et al, 2020; Manning, 2009; Mustart, et al, 1997; iNaturalist).
