    The five pink-purple, perianth lobes of Aizoon-like flowers resemble petals on their inside surfaces, slightly sac-like near their tips. They spread around the superior ovary that is deeper coloured than the perianth insides. The outside surfaces of the perianth lobes are leaf-like or sepal-like; dark green to dull green, covered in large water cells and a few hairs.

    At least nine stamens emerge from the gap between the ovary and the spreading perianth lobes. Their soft, fleshy filaments angle out, slightly thinner near their tips than lower down. The filaments are coloured as the perianth although whitish in parts. The short, thick anthers are two-lobed and yellow to yellow-brown, finely granular with pollen grains. Each anther is attached to its filament tip near the midpoint.

    In one flower in picture the styles still cohere in an attenuating cylinder or cone on top of the bulbous ovary, while an older flower present has four style branches deeply divided, the upper parts of separate carpels.

    This structure of the female floral component is unlike the Aizoon paniculatum flowers also shown in this Album. Those display six style branches that only separate high up on the style and curve down, whitish in colour while the ovary is green, the stamens thinner and more in number (Leistner, (Ed.), 2000; iNaturalist).
