Stapelia leendertziae, commonly known as black bells, is a species of succulent plant[2] in the family Apocynaceae that is native to Southern Africa.

[4] It forms succulent stems, with matt green to slightly shiny, more or less slender, four-ribbed shoots, the sides of which are strongly concave.

The purple flower bud is spherical or longitudinally oval and tapered at the apical point.

The corolla lobes are about 1 × 1 cm in size, triangular and moderately to strongly curved outwards.

Its flower mimics the smell, color, and texture of decaying flesh to attract flies to lay their eggs on its corolla as a form of pollination.The fruits stand individually and grow up to 15 cm long.
