|discussion=<p>Reports of <i>Arisaema dracontium</i> occurring in New Hampshire and Rhode Island have not been substantiated by specimens. The species has also been reported from Nuevo Le&oacute;n and Veracruz, Mexico (E. Matuda 1954); more study is needed to determine if these plants are conspecific. Specimens with a wider spathe blade than is typical in <i>A. dracontium</i> have been collected in Florida and Georgia, and these forms may represent intermediates between <i>A. dracontium</i> and the Mexican species A. macrospathum Bentham, which has an expanded spathe blade. D. G. Huttleston (1953) treated A. macrospathum as a subspecies of <i>A. dracontium</i> in his dissertation, but this change in taxonomic status was never formally published.</p>
