The young Antegibbaeum fissoides fruits in picture are still fleshy. The six drying or dried sepals are angled in various directions on the about conical bodies. Dividing lines among the six or seven locules are becoming visible on the dome-shaped tops of the greenish to pale brown fruits, where stamen or petal leftovers have not yet disappeared completely.

Broad valve wings and covering membranes are present in A. fissoides capsules but no closing bodies. The rough-surfaced seeds are brown. The hard, old capsules can persist on the plants for long (Vlok and Schutte-Vlok, 2015; Smith, et al, 1998; iNaturalist; http://www.llifle.com).
