Perennials, to 10 cm (rhizomes branching). Herbage (sometimes reddish-tinged, especially proximally) glabrous. Stems 1–3 (arching upward). Leaves evenly distributed (proximal often withering before flowering); obscurely petiolate or sessile; blades oblanceolate to lance-linear (sometimes with 1–2 lateral lobes), 2–4 cm × 3–5 mm, bases subdecurrent, weakly clasping, margins entire or wavy (often revolute). Heads 1(–4). Calyculi of 3–5+ (inconspicuous) bractlets. Phyllaries ± 13, 5–7(–8) mm. Ray florets ± 8; corolla laminae 5–10 mm. Cypselae glabrous.
Phenology: Flowering summer.
Habitat: Talus slopes
Elevation: 3000–3700 m
Discussion
Of conservation concern.
Senecio pattersonensis has the aspect of a depauperate S. fremontii with notably narrow leaves. Some plants in collections appear to be intergrades with S. spartioides.
