General Description

Plants subacaulescent from a slender taproot and usually simple crown. Herbage: puberulent. Leaf blades obovate in outline, 4–20 cm long, triternate or tripinnate; ultimate segments well-separated, linear (rarely oblong), 1–12 cm long. Umbels: peduncles ascending, 2–40 cm; rays unequal, 1–7 cm long; involucel bracts few, linear, 2–4 mm long. Flowers yellow Mericarps lanceolate to narrowly elliptic, 7–15 mm long, glabrous; marginal wings 1–1.5 mm wide; oil tubes solitary in the intervals (Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).

Montana plants are varieties triternatum, anomalum (M.E. Jones ex. J.M. Coult. & Rose) Mathias, and platycarpum (Torr.) B. Boivin.
