Perennials, 10–25 cm (roots swollen, 6–10 cm). Stems ± subterranean (except peduncles). Leaves basal; petioles 20–35 mm; blades green, broadly ovate, 30–40 mm, faces glabrous or substrigose (sometimes rugose). Heads borne singly (nodding in fruit). Peduncles hairy. Involucres 12–22 mm. Phyllaries lanceolate. Ray-florets 0. Disc corollas yellow, 6–8 mm. Cypselae 7–12 mm; pappi usually 0, rarely of 2 bristlelike awns. 2n = 36.


Phenology: Flowering Apr.
Habitat: Flat areas with heavy soils
Elevation: 1300–1900 m

Discussion

Encelia nutans shares the apically notched and glabrous-faced cypselae of the genus, but its geophyte habit, especially the ephemeral nature of its aboveground parts, is unique in either Encelia or Enceliopsis.
