The genus Rebutia contains around 29 species of dwarf, clump-forming perennial cacti from the Cactaceae family. These plants are found in mountainous regions of Bolivia and northern Argentina. They are popular for their habit and splash of floral colour. Areoles have many short, bristly spines. Diurnal flowers are borne near the stem bases, making members of this genus popular in temperate greenhouses or as houseplants.
