Rosulate perennial herb, up to 16 cm high. Rhizome robust, with many (up to 35) succulent, up to 200 x 2-4 mm, dark brown to almost black roots; usually with burnt remains of leaf bases. Leaves ±2 to 9, firm, erect, before flowering time at most 1 or 2 leaves or leafless, at flowering time many, up to 30; blade linear, or narrowly elliptic or very narrowly obovate, 40-120 x 2-5 mm; apex acute; base very long, narrowly cuneate petiole-like, petiole-like base silvery lanate adaxially; margin entire, flat, rarely revolute; with single main vein, sometimes with 2 indistinct marginal veins; both surfaces glabrous; coriaceous, flat, bright lime green to reddish brown. Scape 1 to 7, 1- to 8-headed, 60-160 mm long, mostly corymbosely branched from base, dark red-brown to dark purplish, strongly ribbed, sparsely silvery lanate, mostly glandular, bracteate, bracts many, dark purple, very narrowly ovate, lower bracts up to 25 mm long, decreasing in size upwards, acuminate, sessile, semi-amplexicaul, glandular, axils densely silvery lanate. Involucre broadly campanulate to turbinate-campanulate, 11-16 x 14-20 mm. Involucral bracts 30 to 34, in 3 or 4 series, imbricate, surfaces lanate or glabrous, glandular; bracts of outer series narrowly ovate, 4-6 x 1.0-1.5 mm, apex acute to acuminate, margin long fimbriate, purplish; bracts of second series linear or narrowly oblong to narrowly obovate, 6-8 x 1-2 mm, apex acute to acuminate, margin narrowly membranous, long fimbriate, purplish; bracts of third series narrowly obovate to narrowly elliptic, 7.5-10.0 x 1.5-2.0 mm, apex acute to acuminate, margin membranous, long fimbriate, purplish; bracts of fourth series narrowly obovate to narrowly elliptic, 8-10 x 1.5-2.0 mm, apex acute to acuminate, margin membranous, long fimbriate, purplish in upper part. Ray florets 14 to 16, corolla bright violet, pink, mauve or white, ±9 mm long; limb mostly linear, 4- to 6- veined, 3-lobed, mostly uneven, tube sometimes laxly glandular hairy. Style 5-6 mm long; style branches often purplish, elliptic, often uneven or with 3 or 4 branches, 1.5-2.0 mm long, apex obtuse. Staminodes present. Cypsela and pappus as in disc florets. Disc florets many, corolla ±6-7 mm long, not or scarcely longer than pappus; tube glabrous or scattered glandular hairy; lobes mostly recurved, loosely hairy. Anthers 1.2-1.6 mm long, with narrow triangular apical appendages. Style 5.5-6.0 mm long, exserted; style branches elliptic, 0.7-1.4 mm long, sometimes uneven (malformed) or with 3 branches, dark red or purplish; style appendages deltoid, 0.3 x 0.2 mm. Cypselae cylindrical to fusiform, 7.5 x 1.8 mm, dark brown, with 4 to 7 narrow, prominent, cream-coloured ribs; with many, yellowish, shiny glands and long silvery sericeous or straw-coloured or brownish twin hairs, ±0.4-0.8 mm long, apices distinctly unequal in length, acute. Pappus biseriate, outer series of few delicate, reduced, free barbellate bristles up to 3 mm long, dirty white or straw-coloured; inner series of plumose bristles 6.5-8.0 mm long, barbellate and cohering basally, dirty white or straw-coloured, sometimes tinged pale purple. Flowering time: February to June, November, usually after fire. From: Herman, PPJ; Zinnecker, U. 2016. A taxonomic revision of the genus Mairia (Asteraceae, Astereae) in South Africa. S. African J.

M. burchellii is recognised by the rigid, erect, often dark red or brownish, linear or narrowly elliptic or very narrowly obovate leaves. During flowering time, (January) February to May (June), no or at most two leaves are present, as the leaves from the previous growing season are burnt down and only the spiky petiole-like bases are persistent. In M. burchellii, as in M. coriacea, flowering is induced by fire. Plants collected before or long after flowering, usually have many leaves (up to 30), leaves are only present from June onwards. Plants of M. burchellii without leaves resemble M. coriacea plants without leaves and it is almost impossible to separate the two taxa in this condition. M. burchellii can be distinguished from M. coriacea by the linear or narrowly elliptic or very narrowly obovate leaves with a single main vein and entire margins; in M. coriacea, the leaves are mostly obovate, sometimes elliptic to broadly elliptic with 3 to 5 main veins and entire or apically few, broad dentate margins. Although M. coriacea mostly has solitary or 2-headed synflorescences while M. burchellii usually has corymbosely arranged capitula, solitary capitula are also sometimes found in M. burchellii.
