Capitula 3-40, in terminal, laxly corymbiform synflorescences, rarely solitary; peduncles 5-50 mm, villosulous, densely minutely long-stipitate glandular; bracts lanceolate, entire, upper bracts grading into phyllaries. Involucres hemispheric to campanulate, ca. 5 mm; phyllaries 3-seriate, unequal, midvein thin; outer phyllaries linear-lanceolate, 3-3.5 × 0.5-0.7 mm, abaxially glabrous, densely minutely long-stipitate glandular, leaflike, margin not to ± narrowly scarious, ciliate, apex sometimes spreading, acute, sometimes mucronate, sometimes purplish, ciliate, middle and inner phyllaries green distally, base hardened, margin erose, ciliate; middle phyllaries oblanceolate, 3.8-4 × 1-1.3 mm, abaxially densely minutely long-stipitate glandular, margin broadly scarious, ciliate, apex acuminate; inner phyllaries linear-oblong, 4-4.5 × 0.8-1.1 mm, distally densely minutely long-stipitate glandular, scarious.
