Iva frutescens Linnaeus var. oraria (Bartlett) Fernald & Griscom. Northern Maritime Marsh-elder. Phen: Late Aug-Nov. Hab: Brackish marshes and marsh edges, normally on the back side of barrier islands. Dist: NS south to Dare County, NC; as a waif near Galveston, TX

Origin/Endemic status: Native

Taxonomy Comments: The two varieties are morphologically distinct, except in the zone of overlap (NJ south to Dare County, NC), where intermediates will be encountered. Even in the zone of overlap, though, most plants are readily identified to variety. There might be some merit in considering these taxa species, with limited hybridization in a small portion of their total distributions.
