Calyx of pistillate flowers: sepals 2.3–2.8 mm long, ovate to broadly navicular, subequal, the apex often inrolled, convex at the base, oriented at 90° to 110° angle to the pedicel, green, yellowish green toward the base, often purple toward apex, opaque, glabrous or puberulent toward the base and margin, margin scarious and usually with a few lacerations toward the apex, apex obtuse. Corolla (petals) absent. Staminate flowers: Stamens 10, the filaments dimorphic, white, the antisepalous whorl 4.2–4.8 mm long, the alternate whorl 3.9–4.5 mm long; anthers 0.5–0.65 mm long, yellow. Pistillate flowers: Stamens (9–) 10, the filaments weakly dimorphic, the antisepalous whorl 0.5–0.8 mm long, the alternate whorl 0.4–0.5 mm long; anthers 0.15–0.35 mm long, yellow, not producing pollen.
