The flowers of Esterhuysenia drepanophylla grow solitary at stem-tips. There are five fleshy sepals and a pedicel.

The pale pinkish mauve corollas comprise about two rows of narrowly oblong, slightly ascending petals around a nearly cylindrical, yellow-topped cone of stamens. Nectar is produced by a ring of glands positioned in the flower base. Flowering happens in spring and early summer. 

The fruit is five-locular, the capsules becoming woody. The capsules are similar to those of Lampranthus. The expanding keels are parallel at their bases. The covering membranes do not cover the locules fully and there are no closing bodies or valve wings.

The brown seeds are D-shaped and rough-surfaced (Leistner, (Ed.), 2000; Smith, et al, 1998; iNaturalist).
