Antegibbaeum fissoides is a slow growing succulent species forming grey-green tufts of finger-like leaves. Its showy, purple blossoms appear in winter and open during the day.
Note: It is the only species of the monospeciefic genus Antegibbaeum. It differs from Gibbaeum only in the uninterrupted ring of nectar glands in the flowers and the presence of two bracts below the flower and is thought to be a predecessor in evolution.
The huge petals of the plants are also different from the filamentous staminoides of Gibbaeum.
