Inflorescence a compound pseudumbel, usually without lateral cymes; primary involucral leaves (2-)4 or 5, leaflike but broader, ovate-long-triangular, 3-5 × 0.8-1.6 cm, base auriculate, apex acuminate, primary rays (2-)4 or 5, 1-3(-5) cm; cyathophylls 2, similar to primary involucral leaves, 0.9-1 × 0.7-1.1 cm, base cuneate, margin entire, apex subacute. Cyathium stipe 3-5 mm; involucre broadly campanulate, ca. 3 × 4-6 mm, glabrous outside, lobes triangular-ovate, pilose inside; glands 4, transversely elliptic, ± peltate, entire. Bracteoles linear. Male flowers many, exserted from involucre. Female flower: ovary pedicel 3-5 mm, exserted from cup; ovary smooth, glabrous; styles free, persistent; style arms deeply 2-lobed. Fruiting peduncle ca. 5 mm; capsule globose or ovoid-globose, 4-5 × 3.5-4 mm, smooth, glabrous.
