Its scientific name is derived from Ancient Greek echius – "rough husk" - and doros – "leathern bottle" - alluding to ovaries, which in some species are armed with persistent styles, forming prickly head of fruit. Some of the species are commonly cultivated in artificial aquatic habitats.

Mairia crenata is a perennial herbaceous plant of mostly 2–15 cm (1–6 in) high that is assigned to the family Asteraceae. It has a woody rootstock of up to 5 cm (2 in) long, from which brown, fleshy roots develop. The five to eighteen, hard and leathery, spoon-shaped leaves are in one to three rosettes, have a distinct main vein, blunt or pointy tip, often dark red or blackish margins with rounded teeth and a ½–2 cm (0.2–0.8 in) long stalk-like foot, often initially somewhat woolly hairy, on particularly the lower surface and the main vein, but this is easily rubbed off the shiny surfaces. Each rosette produces mostly one, sometimes up to four, mostly rusty or whitish woolly hairy, brown or dark red inflorescence stalks, usually 1½–15 cm long, each with two to eight, initially woolly, line-shaped to oval bracts, the lowest up to 3 cm (1.2 in), decreasing size further up, and carrying mostly one, rarely up to three flower heads. The flower heads have a bell-shaped involucre with about 40 bracts, sixteen to thirty three violet to white ray florets of about 1¼–1⅞ cm long, and many yellow disc florets. The species flowers anywhere between February and December but only after a fire has destroyed the overhead biomass or serious disturbance. It is an endemic species that is restricted to the Eastern Cape and Western Cape provinces of South Africa.
Mairia coriacea is a perennial plant assigned to the family Asteraceae. It has broad, tough and leathery, evergreen leaves. These have a narrowed foot and an entire margin or a few shallow, irregular teeth. They grow in a rosette directly from the rootstock. The plant produces flower heads with one whorl of white to mauve ray florets around many yellow disc florets, with one or few on top of a dark reddish, woolly stalk. Flower heads appear after the overhead vegetation burnt down, often destroying the leaves in the process. It can be found in the southern mountains of South Africa's Western Cape province. It is called leather leaves in English.
Mairia petiolata is a tufted, variably hairy, perennial plant of up to 15 cm (6 in) assigned to the family Asteraceae. Its leaves are in a ground rosette, and have a stalk of mostly 2–5 cm long and an inverted egg-shaped to elliptic, 61⁄2–9 cm (2.6–4.6 in) long and 2–3 cm wide leaf blade, with a toothed margin. It mostly has two flower heads at the tip of the branches of each erect, dark reddish brown scape. The flower heads have a bell- to cup-shaped involucre that consists of 20–24, purplish, overlapping bracts in 3–4 whorls. These protect 12–16 pink, ray florets, surrounding many yellow disc florets. This species was only seen flowering once, in December. It is known from one location in the Langeberg, Western Cape province of South Africa.
