Inflorescences cymose, open to diffuse, 5–20 × 5–20 cm; branches glandular or glabrous, occasionally glaucous; bracts 3, scalelike, 0.5–2 × 1–2.5 mm. Peduncles recurved to cernuous, curved or sometimes straight, slender, 0.3–1 cm, glandular or glabrous. Involucres campanulate, 2–3 × 2–3.5 mm, glandular or glabrous; teeth 5, erect, 0.5–1 mm. Flowers 2–3 mm; perianth white with greenish or reddish midribs, becoming rose or red, glabrous; tepals dimorphic, those of outer whorl oblong to oval, those of inner whorl oblanceolate; stamens included, 2–3 mm; filaments pilose proximally.
