The species are native to South Africa, specifically to Cape Province and the Karoo desert. They grow in rocks and soils incorporating slate, sandstone and quartz. The plants have thick, soft leaves arranged in pairs, which are low to the ground, often grazing the soil surface. They have rhizomes.They sport yellow flowers with narrow petals, sometimes fragrant, around 5 cm diameter, which appear in autumn and winter.
