Both species of Ihlenfeldtia occur in the Northern Cape Province, South Africa. The compact plants have keeled, three-sided leaves, and showy flowers. They resemble Cheiridopsis species but the seed capsules resemble those of Titanopsis. They blossom in early spring and the flowers open midday and close at dusk. They need warmth, well-drained soil, and plenty of water during their active season in autumn and winter. They are easily propagated by seed.
