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 antholyza is a South African endemic species from the Eastern Cape, Northern Cape and Western Cape Provinces. It was previously known as Anapalina longituba, Anapalina nervosa, Anapalina revoluta, Antholyza nervosa, Antholyza spicata, Gladiolus antholyza, Gladiolus nervosus, Tritoniopsis longituba and Tritoniopsis nervosa. Vernacular names include Bergpypie, Karkaar, Karkaarblom, Rooipypie and Karkarblom. It grows to 90cm tall with lanceolate to linear leaves. From summer to autumn it bears tubular yellowish pink to red flowers with dark streaks.
