Aizoaceae or Ficoidaceae (the fig-marigold family or ice plant family) is a family of dicotyledonous flowering plants containing 135 genera and about 1900 species. They are commonly known as stone plants, carpet weeds or vygies. Species that resemble stones or pebbles are sometimes called mesembs. Several species are known as "ice plants" because of the glistening globular bladder cells covering their stems, fruit and leaves.
