Description:
Annual herb 7-40 cm tall, usually with several erect unbranched stems; stems sparsely to moderately scabrous with coarse glandular hairs and densely pubescent with minute sessile glandular hairs; leaves basal on each stem, linear-oblanceolate to linear, flat, with a usually entire, sometimes shallowly sinuate margin, acute apex and sheathing base, 0.3-14 cm long, 2-10 mm wide, scabrous-pubescent on both sides like the stems.
Capitula solitary, on peduncles 7-40 cm long, broadly campanulate, 8-12 mm long, 10-20 mm broad (excluding the laminae); involucral bracts 4- or 5-seriate, the inner ones longest; inner bracts numerous, in 2 series, with oblong-elliptic to narrowly oblong-elliptic subacute pink to white scarious opaque laminae 6-12 mm long, and broadly oblong colourless hyaline claws a third of their total length with an opaque subherbaceous midrib; florets all bisexual, numerous, of which up to a third, around the periphery, are fertile.
Achenes cylindrical-fusiform, slightly curved, markedly but gradually contracted in the upper third, very slightly compressed, grey-brown, densely to very sparsely tomentose with short patent hairs; pappus bristles of fertile florets 50 or more, stramineous and shortly plumose at the base, deep-pink and shortly plumose in the lower third to half above the base, white and grading to barbellate in the upper half to two-thirds of infertile florets, shortly plumose, pale-stramineous, rather fewer.
