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 woodlands. Flowering Apr–May. 100–1600 m. Sisk. Native.

In addition to morphological traits, DNA evidence implies that F. gentneri is a hybrid between F. affinis and F. recurva (Meyers 2006). Whether this proposed hybridization event was recent or older warrants more study.
