Heads in compact, racemiform arrays. Peduncles (ascending) 1–7 mm. Involucres turbinate-campanulate, 5–7 × 4–5 mm. Phyllaries in 2–3 (–4) series, lanceolate to oblong or elliptic-oblong, unequal, essentially glabrous, margins with (pinkish purple) hyaline borders, apices usually rounded-retuse and minutely involute-cuspidate to apiculate.
