Chamaegigas is a genus which contains only one species, Chamaegigas intrepidus, an aquatic plant that is native to central-west Namibia, growing in semi-arid and savanna regions. It grows in shallow temporary pools on granite inselbergs, surviving regular environmental extremes that include drastic daily changes in temperature and pH, along with extreme fluctuations in wetting and drying. Chamaegigas intrepidus means "intrepid dwarf giant", referring to the tiny plant's ability to thrive even in the desert.
