Leaf blades suborbicular, palmately divided into 5 to 9 oblanceolate, dentate to deeply lobed, glabrous to tomentose leaflets 2–8 cm long. Inflorescence a many-flowered, sericeous, sometimes glandular, open cyme with ascending branches. Flowers: sepals lanceolate, 3–8 mm long; bracteoles narrower and shorter; petals yellow, 5–10 mm long. Achenes smooth, 1–1.5 mm long (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press.
