Description
The main root of the plant is large and woody, with high concentrations of lignin. Towards its top, it is covered in lance-shaped scales that are 2–6 millimeters long. The stems grow upright from the underground caudex in dense clumps. The leaves grow from the stem in an ascending spiral, becoming larger in area the closer they are to the end of the stem. The leaf blades are nearly circular, or are rounded at the end and tapering to the base. They measure 5–10 by 1–6 mm and are covered in dense white hairs on their underside. Each leaf is attached to the stem by a petiole 1–4 mm long.The flowers grow individually on the ends of each stem. The protective sepals are yellow-green or purplish in color, and are sometimes covered in dense brown hairs. The flower petals are yellow, but can sometimes have purple or red veins. Towards their ends they are hairless, but there are many threadlike hairs towards the center of the flower where the petals meet. The ovary extends up to this point, while the seed capsules extend above it. The seeds are oval-shaped, smooth, and roughly 1.3 mm long. The species flowers from July to August.
