Discussion

Of conservation concern.

Fritillaria gentneri is a restricted endemic closely allied with F. recurva and F. affinis, with which it can be confused. Some evidence suggests that it may represent a hybrid between those two species. More study is needed to determine whether it should remain recognized as a distinct species.

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.
