A diffuse, sparse, sprawling shrublet to 0.3 m; straggling prickly shrublet. Stems densely leafy, branching with 2-6 branches from below the previous seasons' capitulum. Leaves linear to lanceolate, broad and flat, broadest at the base, 5-25(-32) x 2-3(-6) mm, erect, spreading, reflexed or recurved, generally glabrous, glandular and silky-hairy on margins. Inflorescence terminal, composed of a number of capitula, mostly 9 but occasionally 10 or 11, grouped together in a secondary head, these heads 20-25(-40) mm in diameter; outermost row of florets radiate, occasionally with a few underdeveloped rays in the centre. Capitula mostly radiate with central capitulum mostly discoid. Involucral bracts of secondary heads in several rows, green and leaf-like, 2-3(-10) mm wide, lanceolate, broadest in the middle, with a prominent midrib, margins of inner leaf-like bracts densely, silky-hairy towards the base. Bracts around central capitula almost translucent, delicate and papery. Ray florets collectively between 30-40 in secondary heads, but 2-6 per capitulum radiating outwards, in an irregular single or double row; rays bright yellow or orange with reddish-purple underside. Disc florets yellow or orange. Pappus a crown of scales.
