Heads heterogamous, campanulate, ±7-8 x 5 mm, 10 mm when expanded, solitary, sessile at the tip of each axillary shoot, these racemosely arranged and the whole very floriferous. Involucral bracts in 5-6 series, graded, loosely imbricate, inner exceeding flowers, radiating, tips subopaque, white, very acute. Receptacle nearly smooth. Flowers ±23-30, 7-11 female, 16-21 homogamous, yellow, tipped pink. Achenes not seen, ovaries with myxogenic duplex hairs.
