The name Ixia is derived from an old Greek name for a plant noted for the variability of its coloring. Unfortunately, as happened in most genera of the South African Iridaceae, several of the better known species soon became involved in mis-identifications and considerable confusion, much of which has persisted to this day. An updated revision has recently been published in 1999 by Miriam de Vos in South Africa and lists some newly discovered species as well as some changes to bring this species list up to date. Here are the changes within the revision done by Miriam de Vos in 1999, as well as some newly discovered species added. Ixia bellendenii now sunk into Ixia longituba N. E. Br.var.
