Capitula 5-50 (per branch) in terminal compound corymbiform synflorescences, ca. 0.7 cm in diam.; peduncles slender, 5-10 mm, bracts subulate, moderately villosulous to densely tomentulose (hairs white or light brown), sparsely to moderately minutely stipitate glandular. Involucres campanulate, 4-7 × 4-7 mm; phyllaries 4-or 5-seriate, unequal; outer phyllaries distally green, sometimes tip purplish, ovate to lanceolate, 1-2.5 mm, abaxially glabrous or sparsely villosulous to tomentulose, sometimes minutely stipitate glandular, margin narrowly scarious, erose, distally ciliate; inner phyllaries distally or only tip reddish purple, lanceolate to linear-lanceolate, 3-5 × 0.5-1 mm, margin broadly scarious, erose, distally ciliate, midvein distally swollen, translucent, apex acute. Ray florets 10-25, white, pink, or purple, tube hairy above, lamina 2-7 × 0.5-1.2 mm, glabrous, eglandular; disk florets yellow, sometimes becoming purplish, 4-6 mm, limb narrowly campanulate, 2.5-3.5 mm, base sparsely to moderately hairy, lobes spreading to reflexed, triangular, 1-2 mm, glabrous, eglandular or glandular.
