Astranthium integrifolium (Michaux) Nuttall. Eastern Western-daisy. Hab: Limestone glades, barrens, rocky woodlands, roadsides. Dist: Nc. KY south through c. TN to nw. GA and ne. AL (primarily in the Interior Low Plateau); disjunct in c. MS (where a waif) and also disjunct in nc. WV, where presumably introduced.

ID notes:Differing from Dichaetophora by its absence of winglike cypsela margins.

Origin/Endemic status: Endemic

Taxonomy Comments: The related A. ciliatum (Rafinesque) Nesom of the Ozarkian region and Texas has sometimes been treated as a variety, subspecies, or unnamed component of A. integrifolium, but see Nesom (2005a) for rationale for recognition at the specific rank, which renders A. integrifolium endemic east of the Mississippi River.
