Cauline leaves ± scattered over proximal 1/4–1/2(–3/4) of plant heights, internodes mostly 4–10 cm; lobes mostly linear to filiform, sometimes ± oblong, 25–50(–120) × 0.5–1+ mm. Calyculi of 6–7+ narrowly triangular bractlets 2–4 mm. Ray florets 8; laminae yellow to golden, usually proximally, sometimes almost wholly, suffused with red-brown or with a red-brown spot or band, 10–20+ mm.
