Zygotritonia is a genus of herbaceous, perennial and bulbous plants in the family Iridaceae. It contains four species distributed throughout sub-Saharan Africa.Peter Goldblatt. 1989. Revision of the tropical African genus Zygotritonia (Iridaceae) . Bulletin du Muséum national d'histoire naturelle. Section B, Adansonia (Bull. Mus. natl. hist. nat., Sect. B, Adansonia) vol. 11, no2, pp. 199-212 . The genus name is derived from the word zygomorphic (meaning bilabiate), and the apparent resemblance to some species in the genus Tritonia.
