Spartina Schreber. Subfamily: Chloridoideae. Tribe: Zoysieae. Subtribe: Sporobolinae. clade: "PACMAD".
A genus of about 15 species, perennial herbs, of the northern Hemisphere. The recognition of this genus is controversial following the work of Peterson et al. (2014a, 2014b), which shows Spartina as derived from within Sporobolus. Alternate possibilities to including Spartina in Sporobolus (the course taken by Peterson et al. 2014a, 2014b) include splitting Sporobolus into smaller monophyletic groups. For now and awaiting further study and potential taxonomic changes, we retain an apparently paraphyletic Sporobolus and recognize Spartina.
