HABITAT: Salt and brackish marshes.
COMMENTS: MA and MI south to s. FL and TX (mostly on the Coastal Plain), also in w. United States, Central America, and South America. Two varieties are sometimes recognized, the widespread and more robust, but small headed var. odorata (involucre 4-6 (-7) mm across the disk, with 6-13 (19) functionally staminate flowers; plants 2-8 (-20) dm tall; of VA southward), and the northeastern North American and less robust but large-headed var. succulenta (involucre 7-8 (-10) mm across the disk, with (14-) 21-34 functionally staminate flowers; plants 2-6 dm tall; of NC northward). Additional study is needed to warrant recognition of the varieties.
