Rhadamanthus is a genus of the family Hyacinthaceae. Rhadamanthus is named after a Greek mythological character. He is the son of Zeus and Europa who became one of the three judges of the Underworld. Many of the species in the genus Rhodocodon created in 1881 were placed into Rhadamanthus in 1998. In A revised generic synopsis of Hyacinthaceae in sub-Saharan Africa (2004) Manning et.al. included this genus in the genus Drimia along with other genera once separated. In 2018 in Systematics of Drimia Goldblatt and Manning continued to include the South African species in this genus in Drimia. There is no agreement in 2023 about whether species from Madagascar should be included in Drimia, Rhadamanthus, Rhodocodon, or some other genus.
