Fritillaria glauca
Liliaceae
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.
Cosmopolitan. 15 genera; 9 genera treated in Flora.
Due to taxonomic changes proposed by Stevens (2001), most genera formerly contained within Liliaceae have been placed in other families, most notably Amaryllidaceae and Asparagaceae.
