Discussion | Fritillaria pinetorum is easily confused with F. atropurpurea. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
This species is highly variable and shows evidence of either being of hybrid origin between Fritillaria recurva and F. micrantha, or, if it is of separate origin, appearing to hybridize easily with those two species. In the northern part of its range, F. eastwoodiae intergrades with F. recurva, whereas in the southern part of its range it intergrades with F. micrantha. Occasional individuals throughout the range display traits of both F. recurva and F. micrantha. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
