Flower heads hemispherical, 3–5 mm long, 1.5–6 mm wide. Involucral bracts green to brown, broadly ovate or obovate to broadly obovate, 0.9–2.6 mm long, 0.6–2 mm wide, obtuse or subacute, glabrous or rarely with scattered hairs on margins and abaxial surface, fertile or sterile, not reflexed at maturity. Floral bracts hyaline, white or green or brown, rhomboid-oblanceolate or oblong-oblanceolate, cucullate, 1.1–2.3 mm long, 0.3–1.5 mm wide, obtuse or subacute, glabrous or very rarely with marginal and/or abaxial white hairs. Receptacle glabrous, narrowly to broadly conical to globular. Male flowers 1.2–2.2 mm long, dimorphic with smaller flowers with larger anthers towards centre; sepals 3, free, hyaline, dimorphic, two larger, 0.8–1.6 mm long, 0.2–1 mm wide, one smaller, 0.8–1.3 mm long, 0.1–0.4 mm wide, linear to obovate/oblanceolate or spathulate, hooded at apex, obtuse to subacute, glabrous or with scattered to moderately dense white hairs on margins and/or abaxial surface, rarely only on apex; petals 3, dimorphic, one lobe larger and two slightly smaller, elliptic to obovate or ovate , obtuse to subacute, pubescent with sparse to dense white marginal hairs, sometimes on abaxial surface, rarely only on apex; stamens 6; anthers dark brown to black. Female flowers 1.4–2.0 mm long; sepals 3, free, hyaline margins, dimorphic, larger lateral sepals navicular, 1.1–2.0 mm long, 0.4–1.0 mm wide, acute or obtuse, with thick and fleshy dorsal keel with hyaline (rarely crenulate) margins, lamina gradually tapering to subsessile base, glabrous or with isolated white hairs on margins and keel, or scattered to very dense white hairs on margins and sometimes keel and/or abaxial surface; median sepal narrowly linear-lanceolate to lanceolate or oblanceolate, 0.6–1.6 mm long, 0.1–0.4 mm wide; petals 3, dimorphic slightly in size only, narrowly oblong–oblanceolate/obovate, 0.9–1.9 mm long, 0.1–0.5 mm wide, obtuse, pubescent with scattered to dense marginal and/or apical white hairs; ovary 3-locular. Seeds 0.6–0.8 mm long, 0.4–0.6 mm wide, smooth, lacking sculpturing or epidermal cell outline only faintly visible or with obscure peg-like projections on transverse walls.
