Stem leaves   significantly smaller than basal ones, with narrow sheaths 15–17 mm long, 2–3 times pinnate, with subfiliform leaf lobes up to 5 cm long; terminal umbels up to 15 cm ⌀, with 16–20 thickened, scabrous, sometimes unequal rays 4–7 cm long; number of bracts 7–10, lanceolate-filiform, with white margins, scabridulous at base, up to 2 cm long.
