Cauline leaves: (nearly all opposite or mostly alternate) largest proximal to mid stems; blades ± 3-nerved, lance-ovate or oblong-lanceolate to lanceolate or linear, 5–26 cm, faces ± hirsutulous to scaberulous or glabrescent. Heads usually borne singly, sometimes 2–3+, erect. Involucres hemispheric, 15–25 mm diam. Phyllaries lanceolate (sometimes outer 2–3 foliaceous; margins usually ciliate, abaxial faces densely hairy or glabrate). Paleae chartaceous, relatively firm. Ray florets (10–)12–16; laminae 15–20+ mm. Disc corollas yellow.
