And on slightly drier mid-regions of the marsh where differing species of Glassworts (brighter-green, top left) and other halophytes like Sea-Lavender, Oraches and Annual Sea-blite (the latter of which has turned pink in this photo) might be found.

Not to be semantically confused with : Saltmarsh Sedge (Carex salina), Saltmarsh Goosefoot (Chenopodium chenopodioides) nor Saltmarsh Rush (Juncus gerardii) [other species found in saltmarshes with similar names]

Easily mistaken for :

  • Reflexed Saltmarsh-Grass ()(Puccinellia distans) but that has flower spikelets only on the further half of the branches and which are outspread, or turned downwards. Mostly avoids the west of the UK apart from Merseyside, and Lancashire.
  • Borrers's Saltmarsh-Grass (Puccinellia fasciculata) has just one-sided and erect flowering clusters which are rather stiff. Found in drier (upper) saltmarshes. Found mostly in the far corner of SE England.
  • Stiff Saltmarsh-grass (Puccinellia rupestris) usually prostrate again with one-sided clusters.Found only in the South of England south of Manchester, and mostly only East of London or on the South coast near IoW anf Brighton, or around Bristol.
