Fruiting pedicels straight, 5–11 mm, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, sometimes minutely hirtellous, hairs sharp-pointed, eglandular. Fruiting calyces winged, plicate-angled, campanulate becoming ovoid-ellipsoid to campanulate, distinctly inflated, 5–6 mm, margins distinctly toothed or lobed, sparsely, minutely hirtellous, eglandular, sometimes sparsely sessile-glandular, lobes pronounced, erect.
