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. |
