Flowers: buds with free tips 1–3 mm; floral tube 20–45 mm; sepals 14–20 mm; petals yellow, fading reddish orange, 15–25(–35) mm; filaments 10–20 mm, anthers 7–11 mm; style 30–60 mm, stigma surrounded by anthers at anthesis. Capsules 30–40 mm, subtending bract not adnate to capsule base. Seeds 1.4–1.8 × 0.5–0.7 mm. 2n = 14.
Phenology: Flowering Apr–May.
Habitat: Open, disturbed sites.
Elevation: 10–500 m.
Distribution
Introduced; Calif., South America (Chile), introduced also widely in temperate, semiarid regions.
Discussion
Subspecies stricta has been collected in several counties near the coast in California (Monterey, Santa Barbara, and Santa Cruz counties) a few times, but the most recent collections are from 1953 and 1995, and it may no longer be naturalized in California. It is naturalized widely in temperate, semiarid areas.
Selected References
None.
