Coastal, mostly saline marshes; N.B. and se. Me. and N.H. to trop. Amer., and rarely and irregularly inland to e. N.Y. and s. Mich.; also in a nonmaritime, often weedy var. in the Ozark reg., n. to Nebr. Most of our plants are var. subulatus, as here described; plants of N.B. have blunter lvs, and a less imbricate, slightly more herbaceous invol, and have been distinguished as var. obtusifolius Fernald.
