Phyllaries 4–6 mm, abaxial faces spreading-hairy (hairs mixed, short, slender hairs and longer bristles), densely glandular, tack-glands usually 0. Paleae 4–6 mm (tack glands usually 0). Ray florets 1–4; corollas yellow, white, or rose, tubes ca. 2 mm (papillate, throats often with red "eyes"), laminae 5–6 mm (central lobes slightly narrower than laterals, nearly symmetric, widest beyond middles, sinuses usually 3/4+ laminae).
