Discussion | This species has the widest geographic distribution in the genus. It is easily confused with Fritillaria pinetorum as there is no one consistent, distinguishing trait. These two species are most easily identified in the field, but herbarium specimens can be successfully identified using a combination of flower posture and cauline leaf traits. In F. pinetorum the flowers are almost always erect, although some of the flowers may be ± spreading. In F. atropurpurea the flowers are nodding, with some flowers sometimes ± spreading. The habit of the flowers can be easily confused in pressed specimens, so careful attention to cauline leaf traits works best for them. Fritillaria pinetorum has long proximalmost cauline leaves that surpass the inflorescence, whereas the proximalmost cauline leaves in F. atropurpurea almost never exceed the inflorescence. For accurate identifications, it is best to look at several individuals from a location. The Lakota tribe used the whole plant of this species as a cancer cure. Plants were pulverized into a salve and applied to scrofulous swellings. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Fritillaria striata is considered rare and endangered in California, the greatest threat at present being loss of habitat due to cattle grazing. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
