Salicornia ambigua Michaux. Woody Glasswort, Perennial Glasswort, Guinea-bead, Wild Coral. Phen: Jul-Oct. Hab: Coastal salt marshes, primarily in salt pannes. Dist: NH south to FL, west to TX (at least); south through the West Indies to n. South America.

Origin/Endemic status: Native

Taxonomy Comments: Ball in FNA (2003b) treats all North American Sarcocornia as Sarcocornia pacifica, which is also present on the Pacific coast of North America. Sarcocornia perennis is restricted to the Pacific and Atlantic coasts of North America, as well as being in Europe, sw. Asia, and Africa. Alonso & Crespo (2008) clarify the species-level taxonomy of Sarcocornia in a paper focused on South America, and treat eastern North American material as Sarcocornia ambigua, a conclusion here followed, except that we also accept the inclusion of Sarcocornia in Salicornia (Piirainen, Liebisch, & Kadereit 2017).
