Larryleachia cactiformis (also known as the cactus barrel milkweed) is a stapeliad succulent, native to the Richtersveld and Namaqualand in South Africa, where it grows in rocky areas.

True to its name, Larryleachia cactiformis grows in the shape of a small cactus, with no leaves, spines or branches but ribbed with mammillae on 4-6 sided protrusions.

It is greyish green in colour and starts spherical, then grows into a short cylindrical stem of 4-6 inches high, and sometimes taller in captivity.

The species has two varieties: Larryleachia cactiformis is found in the Richtersveld and in the Bushmanland region of Namaqualand in the Northern Cape, from Sendelingsdrift to Garies.

[2] The usual problems for cultivation of Larryleachia apply to L. cactiformis, primary of these being the need for year- round warmth and sunlight, and the dangers of root rot and mealy bugs.
