Homoglossum is a genus in the Iridaceae family named in 1866. Species were described as having flowers that were orange to red, long tubed and adapted to pollination by sunbirds. Along with Oenostachys and Anomalesia, genera with the same characteristics, it was included by Peter Goldblatt and M. P. De Vos in 1989 in Gladiolus. Several of the species listed below were named Homoglossum at one time but were not included in that genus when it was revised. A few of the species are now included in Tritoniopsis.
