Flowers nodding; tepals pale greenish yellow to red, narrowly elliptic, 1–1.7 cm, apex usually flared to slightly recurved; nectaries green, gold, or yellow, lanceolate, less than 1/3 tepal length; style obviously branched for less than 1/2 its length, branches barely recurved, longer than 1.5 mm. Capsules angled. 2n = 24, 34, 36.

Discussion

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.
