Carpobrotus mellei (commonly known as mountain sourfig, Berg suurvy) is a succulent perennial of the family Aizoaceae, native to the inland mountain ranges of the Western Cape, South Africa.

The leaves are usually a glaucous green, sometimes reddish along the leaf's edges or angles.

The leaves are also somewhat flattened laterally, causing them to form an isosceles triangle in cross-section.

[1] Carpobrotus mellei can be distinguished from other similar species in the genus, by a combination of its very long stigmas (usually rising above the stamens), its barrel-shaped or turbiniform receptacle, and by its higher altitude sandstone mountain habitat.

Its fruits are edible and are grazed by tortoises and other southern African animals.
