Discussion

The rhizomatous habit, leaves that are glabrous upon expanding, and densely hairy ovary apices in Amelanchier fernaldii are a distinctive combination of characteristics. Its relationships to congeners are unclear. Access to flowering material clearly assignable to A. fernaldii has not been available, and the size of floral parts was taken from M. L. Fernald (1950).
