Inflorescences: lateral glomerules 1.8–3.5 mm diam.; bracts similar to cauline leaves. Flowers: perianth segments (4–) 5, connate for most of their length, urceolate, tube with distinct reticulate veins, distinct portion 0.1–0.5 mm, margins dentate, apex rounded to broadly acute, accrescent and coriaceous with age, enclosing fruit; stamens 5; stigmas (2–) 3 (–5). Achenes obovoid; pericarp loosely adherent, membranaceous, with many yellow glandular-hairs near apex, otherwise smooth. Seeds vertical, suborbicular to ovoid, 0.8–1.3 × 0.8–1 mm; seed-coat smooth.
