Inflorescence anthelate or umbelloid, rarely ±congested, of 1–10 (–20) hemispherical to cup-shaped 2–10 (–20)-flowered clusters c. 5–7 mm wide. Capitulum bracts ±ovate-lanceolate, stramineous to castaneous, to c. 2.5 mm long. Tepals ±unequal; outer tepals shorter or equalling inner ones, lanceolate, carinate, acuminate to acute, 1.5–3.0 mm long, pale castaneous-brown with paler ±minutely papillose to smooth midrib; inner tepals subobtuse, ±ovate, c. 2.4–3.0 mm long, broadly membranous-bordered. Stamens 6; anthers 0.4–0.8 mm long; filaments 0.4–0.6 mm long; style 0.2–0.4 mm long; stigmas 0.6–0.8 mm long.

Seeds broadly ovoid, 0.4–0.6 × c. 0.35 mm, pale brown, faintly reticulate; appendages absent. Fig. 51.
