Annuals, 15-40 cm; slenderly taprooted. Stems initially erect, later ascending to decumbent (herbaceous), proximally spreading- to deflexed-villous, closely to loosely strigose on distal 1 / 3 - 1 / 2 , eglandular. Leaves basal (often drying translucent, often withering by flowering) and cauline; basal (thin) blades oblanceolate to obovate or spatulate, 10-80(-140) × 5-34 mm, cauline slightly or gradually reduced to distal 1 / 3 of stems (bases clasping), margins usually with 1-4 pairs of teeth or lobes, sometimes entire, faces sparsely short-hirsute to hirsuto-villous, eglandular. Heads (1-)3-10(-20) in diffuse arrays (branches from distal 2 / 3 ). Involucres 2.5-3 × 5-10 mm. Phyllaries in 2-4 series, hirsute to sparsely villous, minutely glandular. Ray florets 95-160(-250); corollas white to bluish, 2.5-4 mm, laminae not coiling or reflexing. Disc corollas 1.7-2 mm. Cypselae 0.6-0.8 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 10-13(-15) bristles. 2n = 18. Flowering Feb-May.
