Aizoaceae
The Aizoaceae, or fig-marigold family, are a large family of dicotyledonous flowering plants containing 135 genera and about 1,800 species. Several genera are commonly named ice plants or carpet weeds. The Aizoaceae are also referred to as vygies in South Africa. Some of the unusual Southern African genera—such as Conophytum, Lithops, Titanopsis, and Pleiospilos —resemble gemstones, rocks, or pebbles, and are sometimes called living stones or mesembs.
