Zygotritonia

Zygotritonia is a genus of herbaceous, perennial and bulbous plants in the family Iridaceae. It contains four species distributed throughout sub-Saharan Africa.^[2][3] The genus name is derived from the word zygomorphic (meaning bilabiate), and the apparent resemblance to some species in the genus Tritonia.^[4]
