Species?

Is it possible to get this to species level from the pictures here?

The multiple fruiting heads on the stem ...

... means that it's not Eriophorum vaginatum. That leaves three species, but Eriophorum angustifolium is the commonest by a wide margin.

It doesn't appear to have bristles on the spikelet stalk, and doesn't appear to have a distinctly 3-angled stem, both of which would make it Eriophorum angustifolium, but I'm not sure that those characters can be reliably evaluated from these photographs.

Thanks

I've added a couple more detailed pictures of the stalk in case that helps. But I suspect this one will have to remain at genus level.
