Dedoublement is very common in the androecium, and in Mesembryanthemum, the outer stamens are represented by petaloid staminodes. The ovary is usually superior with axile placentation, but in Mesembryanthemum it is inferior, and multilocular, with parietal placentation. The fruit is a capsule. Mesembryanthemum is the most important genus.
