Seems like a good suggestion Jane, maybe wait to see what Ciaran says

No this isn't Juncus vaginatus, or at least the infloresence in the first two photos aren't. It does looks likes there might be spent infloresence of that species in the bottom of the frame however. Assuming the infloresence and pith etc. are from the same plant, then this is one of the "large-flowered" group. I reckon there are three possibilities, Juncus continuus, Juncus flavidus & Juncus sarophorus. In my view Juncus continuus is probably the strongest possibility.

Followed up your suggestions, and Juncus continuus is best fit, so am making that suggestion.
Several characteristics do not match for J. sarophorus (culm firmness, culm colour, type of pith, description of cataphylls ...) and few don't match for Juncus flavidus (culm firmness, pith character). J flavidus

No issues Luke, very few people are any good at them. Lots of species that look similar morphologically.

Yes seems to be a bit of a mindfield... maybe one day you can give me a bit of a teaching if we get together....
