Distichlis spicata (Linnaeus) Greene. Saltgrass, Spike Grass. Phen: Late May-Oct. Hab: Coastal marshes and shores, especially common in hypersaline flats (where infrequent tidal inundation is followed by evaporation). Dist: Widespread in the Americas.

ID notes: Sporobolus virginicus is superficially similar to Distichlis spicata in overall aspect (a rhizomatous grass in coastal saline conditions with distichous leaf arrangement), but is generally more delicate and has hairy sheath margins and collar (vs. coarser and glabrous in Distichlis spicata).

Origin/Endemic status: Native

Taxonomy Comments: Two varieties (or subspecies or species) have often been recognized: var. spicata ranging along the Atlantic coast from NS and PE south to tropical America, and on the Pacific coast of North America, and var. stricta (Torrey) Lamson-Scribner widespread in saline situations in western North America. These do not appear to warrant taxonomic recognition (Barkworth in FNA 2003a).

Other Comments: "One of the chief components of 'marsh hay' " (Tatnall (1946).
