1. Achillea aspleniifolia Vent., Descr. Pl. Nouv.: tab. 95. 1802.

Lectotypus (designated here): [UNITED STATES]: Hort. Cels, Ventenat s.n. (G [G00341485]!).

= Achillea millefolium L.

Notes. – Two different collections have been located in Ventenat’s herbarium at G. The plant collected by Michaux from his travel to North America (G [G00341484]) and the plant cultivated in Cels’s garden. The latter is designated here as the lectotype as it is more complete and clearly served primarily for the description of Achillea aspleniifolia. No specimen has been located at P.
