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.
