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.
Selected References
None.
