Baccharis dioica
Baccharis angustifolia
Baccharis dioica is known from the southern tip of Florida. It is distinguished by its obovate, entire leaves with broadly obtuse apices, spreading phyllaries, and pappi that scarcely elongate in fruit.

Baccharis angustifolia is most commonly found in brackish, marshy areas near the coast of Atlantic and Gulf coastal plains. It is easily recognized by its 1-nerved, relatively narrow and fleshy, entire leaves, and the more or less pyramidal arrays of relatively small heads. Rarely, some specimens have slightly broader leaves with an occasional tooth, perhaps due to introgression with B. halimifolia.
