Rebutia is such a genus with a great variety of species. It belongs to the family Cactaceae. These beauties occur in the hilly regions of Bolivia and Argentina. The genus got its name after a French cactus lover, Monsieur P. Rebut. Let’s take a look at some prominent and beautiful species in genus Rebutia.
