Middle and upper cauline leaves similar to basal, but reduced; lamina 6–30 cm long, 4–12 cm wide; sheaths as long as or half the length of petiole. Inflorescence paniculate in the middle part of stem, mostly composed of sterile flowers; verticillate fertile inflorescence in the upper part of stem. Umbels sessile or on a peduncle up to 5 mm long, with 8–12 rays 1–4 cm long; bracts 6–7, linear-lanceolate, entire, 3–7 mm long, herbaceous, persistent in fruiting time. Umbellules 10–20-flowered, pedicels 1–4 mm long at flowering time, 3–8 mm long at fruiting time; bracteoles 5–7, linear-lanceolate, entire, 2–4 mm long, herbaceous, inflexed. Sepals up to 0.5 mm, ovate, margin hyaline, acuminate at the tip.

Filaments 1.5–2.5 mm long, anthers ± oblong, 0.5–0.75 mm long. Stylopodium shortly conical, styles up to 0.6 mm long. Styles up to 2.5 mm long in fruit reflexed.
