Rebutia is a genus in the family Cactaceae, containing 41 species. They are native to Bolivia, Peru and Argentina.
In 1895, Karl Moritz Schumann named the genus after P.Rebut, a French cactus nurseryman. These are generally small, colorful cacti, globular in form, which freely produce flowers that are relatively large in relation to the body. They have no distinctive ribs, but do have regularly arranged small tubercles. They are considered fairly easy to grow and they may produce large quantities of seeds that germinate freely around the parent plant.
