Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words (lthos), meaning stone, & (ps), meaning face, referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks & are often known as pebble plants or living stones. The formation of the name from the Ancient Greek -ops means that even a single plant is called a Lithops.
