Three new species of Tritoniopsis (Iridaceae: Crocoideae) from the Cape Region of South Africa

Three new species of the largely Western Cape genus Tritoniopsis L.Bolus are described, bringing the number of species in the genus to 24. Tritoniopsis bicolor and T. flava are newly discovered, narrow endemics of the Bredasdorp Mountains and the Kogelberg Biosphere Reserve, respectively, in the southwestern Cape. Both of these are areas of high local endemism. T. toximontana, known since at least 1465 but misunderstood, is restricted to the Gifberg-Matsikamma Mountain complex of northern Western Cape. Notes on the pollination biology of the species are provided.
