Tritoniopsis is a perennial genus in the Iridaceae family that is found mostly in the southwestern Cape of South Africa, most often growing in sandstone soils in fynbos. Most of the species are summer flowering, flowering when the leaves are dry and withered. Many of them are triggered into flower by fire. This is also easily achieved by scattering ash around the plants and watering it in. Flowers are usually pink to purple or red, but there are some species with white, yellow, brown, or cream flowers. Leaves lack a definite midrib and have more than one main vein.

Tritoniopsis lata is found mostly in the southwestern Cape of South Africa, most often growing in sandstone soils in fynbos.
