|distribution=Del.;Md.;Okla.
|discussion=<p><i>Alnus maritima</i> consists of widely disjunct populations in Delaware, Maryland, and southern Oklahoma. The populations probably represent remnants of Pleistocene and post-Pleistocene distributions and migrations. It is our only member of the predominantly Asian fall-blooming <i>Alnus</i> subg. Clethropsis.</p>
