Leaves pubescent, villous, or sericeous (distal with hairs not notably longer at margins), all or distal glandular. Heads in paniculiform arrays. Peduncles 0 or 1–20 mm, bracts not surpassing phyllaries. Calyculi 0. Phyllaries 4.5–6.5 (–8) mm, apices usually shorter than bodies. Ray-florets 5–14; laminae yellow, abaxially purple-veined. Cypsela widths 0.4–0.63 times lengths. 2n = 28.


Phenology: Flowering Apr–Dec.
Habitat: Grassy slopes, flats, barrens, openings in woodlands or chaparral, often on serpentine
Elevation: 0–500 m
