In view of the confusion that this name transfer would create, and the current uncertainty as to the criteria for priorability of lectotypification (McNeill 1986), it is best to retain the name S. nervosa at present.

STATUS: Rare in Canada. Endangered in Wisconsin; rare in Maryland, New York, and Pennsylvania. NOTES: The common name "harbinger-of-spring" is appropriate for Ehgenia bulbosa, since it is our earliest-blooming native wildflower.
