Filago vulgaris arrived in North America before 1739 (G. Wagenitz 1976). Paucity of modern collections suggests that it may not spread much or persist for long in the flora area. Reports from southern Ontario, Alabama, Georgia, and Kentucky have not been confirmed by me. The illustration of "Filago germanica" in L. Abrams and R. S. Ferris (1923–1960, vol. 4) depicts F. pyramidata var. pyramidata.

I agree with G. Wagenitz’s (1965) nomenclatural analysis. Filago vulgaris replaced F. germanica Linnaeus, which is a later homonym of F. germanica Hudson, which in turn is a superfluous name for F. pyramidata Linnaeus.
