The six species of fire daisy are endemic to the southern mountains of the Western Cape province and the western end of the Eastern Cape province of South Africa.
M. burchellii occurs from Piketberg and Ceres in the north, to the southern Cape Peninsula and the Hottentots Holland Mountains in the south, and eastwards to Bredasdorp.
M. coriacea may be found between the southern part of the Cape Peninsula in the west, and the Hottentots Holland Mountains, following the coast past Cape Agulhas to the mouth of the Breede River at Witsand in the east.
M. crenata has the largest distribution of any species of Mairia.
It has an isolated population on Table Mountain.
From Du Toitskloof Pass and the Hottentots Holland Mountains in the west, it can be found along the length of the Riviersonderend Mountains, the Langeberg, the Outeniqua Mountains and Tsitsikamma Mountains all the way to the Kouga Mountains on the eastern end.
M. hirsuta has a rather limited distribution from near Swellendam to Suurbraak in the Langeberg, and in the isolated range of Warmwaterberg in the Little Karoo to the north.
Only a single population of M. petiolata is known, just north of Swellendam in the Langeberg.
M. robusta grows from Bainskloof in the north, along Stellenbosch Mountain and Hottentots Holland Mountains to the southern coast near the Kogelberg.

Mairia only flowers after a fire has burnt the overhead vegetation.
