Leaves mainly radical, linear, usually entire, 4–30 cm long, 0.1–0.3 cm wide, very rarely with several small linear lobes, mainly glabrous but at least the lower leaves with long, coarse, septate, brownish hairs at the base. Scapes sometimes shorter but usually longer than the leaves, with some linear leaves which reduce in length towards the flowerhead.

Achenes obovate to obovate, 2.4–3.4 mm long, 1.8–2.3 mm wide, brown, concolorous or discolorous, with the wing-like margins paler than the fruit body; fruit body smooth or minutely tuberculate and not or more or less well-defined by longitudinal ridges associated with the vascular traces, glabrous or each tubercle with a hair; wing-like margins non-swollen and with entire edges, the edges with biseriate, curved, eglandular hairs. Pappus of c. 10 scale-like, more or less erect bristles 0.1–0.4 mm long, connate at the base, not exceeding the apical notch of the achene.
