General Description
Perennial from a mostly branched caudex. Stems erect or ascending, glabrate to pubescent, subscapose, 10–60 cm. 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. Fort Worth, TX).

Lesica (2012) recognizes five varieties in MT: var. brunnescens (Rydb.) C.L. Hitchc.; var. fastigiata (Nutt.) S. Watson; var. elmeri (Rydb.) Jeps.; var. flabelliformis (Lehm.) Nutt. ex Torr. & A. Gray; and var. pulcherimma (Lehm.) Fernald. At the present time MT NHP is only recognizing varieties flabelliformis and pulcherrima.
