Discussion

Pluchea baccharis has been reported from Arkansas; I have not seen a specimen.

Pluchea rosea var. mexicana R. K. Godfrey, endemic to inland gypseous-saline habitats in east-central Mexico, has been treated at specific rank (G. L. Nesom 1989).

The geographic ranges of Pluchea baccharis and P. foetida are nearly congruent and the taxa intergrade in morphology. The distinction between them is based primarily on corolla and phyllary color. Features of involucral vestiture also appear to be relatively constant. Head size and shape are not reliable diagnostic features.

Pluchea sagittalis is adventive, probably a waif; it was collected as a ballast weed by C. Mohr near Mobile (1891, 1894, 1896) and by A. H. Curtiss near Pensacola (1886, 1901).
