Discussion

Serpentine and non-serpentine gravelly slopes. Flowering Mar–Jun. 400–2100m. Casc, Sisk. CA. Native.

Fritillaria glauca is our only species that grows in serpentine soils. This species also grows in non-serpentine habitats. This begs the question: Was F. glauca historically a serpentine or non-serpentine endemic? The sickle-shaped and strongly glaucous leaves of F. glauca are distinct among Oregon fritillaries.

Dry open woods and scrubland. Flowering Mar–May. 200– 1500m. Casc, ECas, Sisk. CA, NV. Native.

Fritillaria recurva and F. micrantha are hypothesized by some authorities to be the parental species of F. eastwoodiae (McFarlane 1978). More study is needed.
