Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Naturalised

Annual to c. 25 cm high; flowering stems ascending to erect, often branched. Leaves not (or very weakly) rosetted at base (lower leaves usually withered at flowering) narrowly spathulate to oblanceolate, 15–30 mm long, 2–6 mm wide, obtuse, surfaces almost or quite concolorous, both greyish-cottony, upper leaves commonly longi-tudinally folded and c. falcate, reducing toward (and within) inflorescence. Inflorescence c. paniculate or contracted, but hardly spicate, flower clusters not contiguous (except sometimes the top few), each cluster subtended by a reduced leaf, clusters usually shortly racemose. Capitula 3–4.5 mm long, innermost bracts acute or abruptly acuminate, entire, pale to mid-brown or purplish near apex; bisexual florets 2–4. Cypselas 0.4–0.5 mm long. Flowers mostly Oct.–Jan.
