Umbels: peduncles becoming 10–25 cm long; rays ascending, 3–10 cm long; involucre and involucel absent. Flowers white; stylopodium conic, beak-like. Mericarps erect-hispid, linear-oblong, 11–15 mm long, concavely narrowed to the tip (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
