"Lithos" means "stone" and "-ops" means "face" in Ancient Greek; therefore "Lithops" means "stone-like". This is a very good description of these plants, which avoid being eaten by blending in with surrounding rocks. They are often known as peable plants or living stones. The formation of the name from the greek "-ops" means that even a single plant is called a Lithops. Individual Lithops plants consist of one or more pairs of bulbous, almost fused leaves opposite to each other and hardly any stem. The slit between the leaves contains the meristem and produces flowers and new leaves. The leaves of Lithops are mostly buried below the surface of the soil, with a partially or completely translucent top surface or window allowing light to enter the interior of the leaves for photosynthesis.
