Inflorescence few-flowered, appressed-hairy, open with spreading branches. Flowers sepals lanceolate, 3–5 mm long; bracteoles narrower and shorter; petals yellow, 4–6 mm long, longer than the sepals. Achenes smooth, ca. 1.5 mm long (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
