Mairia robusta
Mairia robusta is a tufted, white-woolly, perennial, herbaceous plant of up to 30 cm (1 ft) high, that is assigned to the family Asteraceae. It has large, robust, hard and leathery leaves, with a white woolly hairy, nontransparent underside, while the felty hairs on the top are lost with age. Only at a few occasions, flowers have been observed, in June, October and December, always after a fire. The flower heads sit individually at the tip of white-woolly scapes, with 14–16 purplish pink to white ray florets surrounding a yellow disc. M. robusta is an endemic species that is restricted to rocky mountain slopes in the Western Cape province of South Africa.
Mairia robusta can be found from Bainskloof Pass in the north, through Stellenbosch Mountain and the Hottentots Holland Mountains, to the coast near the Kogelberg in the south. It grows on the upper rocky slopes near the summit in a fynbos vegetation. Although the distribution range of this species is restricted to about 1,100 km2 (420 sq mi), it occurs in well-protected mountains, and it is therefore considered a species of least concern.
