Involucral bracts in ±9 series, closely imbricate, outer much shorter and broader than inner, glossy brown with a crimson tinge, inner much exceeding the flowers, white or tinged rose-pink to crimson, opaque. Receptacle shallowly honeycombed. Flowers 50-68, 3-8 female, 47-56 homogamous. Achenes 1.75 mm long, ellipsoid, glabrous or with a few duplex hairs. Pappus bristles many, equalling corolla, tips subplumose, shaft scabrid, bases cohering by patent cilia with some fusion as well.
