|discussion=<p>Specimens examined from inland North America that had been attributed to <i>Tripleurospermum maritimum </i>subsp.<i> maritimum</i> were all <i>T. inodorum</i>. The identity of the plant called <i>T. maritimum</i> in St. Pierre and Miquelon is uncertain; I did not have access to the voucher specimens and some plants so labeled in maritime eastern Canada were in fact <i>T. inodorum</i>. I am uncertain as to whether or not this taxon persists in northeastern North America. Some specimens identified to this taxon, even on the coast, may be <i>T. inodorum</i> individuals that have become multi-stemmed through damage or via other mechanisms, particularly on sand dunes. Such specimens are difficult to classify as annual or perennial if the taproot is not dug out, and the lack of cypselae may prevent positive identification.</p>
