The plants were first described as a genus in 1965; the name "Pseudo-lithos" means "false-stone" and refers to their pebble-like appearance. All species in this genus are highly succulent, highly reduced, and exhibit tessellation on their stems' surface. Their small flowers appear on the spherical body's surface.
