Annual, branched, glabrescent herb, 10–40 cm tall. The central stem is short, ending in a hea, with several diffuse stems arising from the axils of the basal leaves. Leaves are sessile, glabrescent, grass-like, filiform to linear, entire and acute, 2–15 cm long and 0.05–0.3 cm wide. Heads are yellow, solitary or in groups of two to three and 6–7 mm across. Ligules are yellow, equal to or slightly longer than the outer bracts. Fruits are long, glabrescent achenes, arranged in a star-shaped pattern, extending to about twice the length of the outer bracts.
