Habit | Perennials; caudex branched, (densely cespitose and forming hemispheric mounds); densely pubescent, trichomes 5-rayed, rays bifurcate near base, fused at base, (strongly tuberculate throughout). | Perennials; caudex branched, (thickened, cespitose); densely pubescent, trichomes 5- or 6-rayed, rays slightly fused at base, furcate or bifurcate, (tuberculate throughout). |
Stems | few to several from base, erect, (usually exceeding basal leaves), 0.3–0.7 dm. |
few from base, well-exserted from basal leaves, 0.4–1(–1.2) dm. |
Basal leaves | blade linear-spatulate, 1.5–4 cm, (base narrowed gradually to petiole), margins entire. |
blade (erect), obovate to orbicular, 1.5–2.5 cm, (base evidently distinct from petiole), margins entire, (folded). |
Cauline leaves | blade spatulate, similar to basal. |

Racemes | crowded in distal 1/3, (4–10-flowered). |
compact, subumbellate. |
Flowers | sepals (pale yellow), oblong to elliptic, 3–4 mm, (median pair usually thickened apically, cucullate); petals (sometimes with slight tinge of orange basally), lingulate, 4–6 mm. |
