Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words lithos, meaning "stone," ops, meaning "face," referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. The formation of the name from the Greek "-ops" means that even a single plant is called a Lithops.
Although variable in appearance, it nevertheless conforms to the typical Lithops morphology with two thick, fleshy leaves (each with a window to allow light into the underground part of the plant), separated by a crack from which a yellow flower appears. In the variety koelemanii the window and the groove are reduced.
