Malephora, belonging to the Aizoaceae family, is a genus of succulent plants in the ice plant family. There are 13 to 17 species in the genus, many of which are known commonly as mesembs. They are native to Africa. During the apartheid era, South African scientists used it to create a chemical poison.

Malephora lutea, commonly known as Rocky Point Ice Plant in English or Geelspringbokvygie in Afrikaans and synonymously known as Hymenocyclus luteus or Mesembryanthemum luteum, is a South African endemic species found in the Western Cape province. It grows into a spreading, often prostrate shrublet. During spring it bears eye-catching yellow flowers.
