Comments: According to Alonso and Crespo (2008) many treatments have recognized Michaux's Salicornia ambigua - from 'Carolina' - as a synonym of the European species S. perennis, however, they accept several morphological characters as evidence that they are distinct. These authors also agree with Kadereit et al. (2006) that Salicornia should be divided into two genera: Salicornia (annuals) and Sarcocornia (perennials) and make the combination Sarcocornia ambigua. They describe the distribution of the species as the Atlantic coast of the Americas, Cuba and neighbouring islands; in South America from Venezuela (and probably also Colombia) to Uruguay. They do not mention Sarcocornia pacifica so the relationship to that taxon is unclear. FNA (Vol. 4, 2003) recognized Sarcocornia pacifica as the species occurring on both coasts of the U.S. with Salicornia ambigua as possibly the earliest name for it; they recognized Sarcocornia perennis as limited to the northwestern coast of the U.S. into Canada. Kartesz (1999) accepted S. pacifica as the species on the Pacific coast and S. perennis for the Atlantic coast. Draft Kartesz data from 2009 recognizes the west coast species as S. pacifica and shows S. ambigua on the east coast and in California; it is unclear whether this is the same treatment as Alonso and Crespo's.
