Treatment appears in FNA Volume 21. Treatment on page 241. Mentioned on page 240.

Perennials, ashy white, to 15+ cm, arachnose to floccose. Stems spreading, often prostrate. Leaves mostly alternate; blades not lobed, spatulate, 10–25 × 3–6 mm, margins entire or toothed. Peduncles 0–5+ mm, tomentose. Calyculi of 3–5 linear bractlets, lengths 1/2+ phyllaries. Involucres obconic, 6–7 mm. Phyllaries 12–14, margins of outer distinct less than 1/5 their lengths, abaxial faces tomentose. Ray-florets 10–15; corollas bright-yellow, becoming greenish, laminae 5 × 3 mm. Disc-florets ca. 60; corollas yellow, 3 mm. Cypselae 2.3–3 mm; pappi of 5 erose scales to 1 mm alternating with 5 lanceolate, 1-aristate scales to 3 mm. 2n = 16.
