Treatment appears in FNA Volume 10.

Herbs annual or biennial, strigillose, especially proxi­mally, also villous and glandular puberulent. Stems erect or ascending, 25–100 cm. Leaves in a basal rosette and cauline, basal 10–15 × 0.8–1.3 cm, cauline 6–10 × 0.6–1 cm; blade very narrowly elliptic to oblanceolate or lanceolate, margins slightly wavy, serrate. 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), 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.

Lower Taxa

"dehiscent" is not a number.
