This is either common or hare's-tail cotton grass as these are the only 2 on the site, anyone know which one?
No identification made yet.
No interactions present.
But what is the little spider that is crouching inside the flower?
Certainly not E. vaginatum - which only has one spikelet - whereas this has two or more. So it's probably E. angustifolium, but I would never assume that just because someone else says that there are only two relevant species on a site that that is the true position. It's probably correct but an open mind is important in field botany. You never know.... always best to come to one's own conclusion.

Thanks for your comments
Do the stalks elongate at all then it may appear as if there are only 1 spike per stalk? and can we tell by the I think they are called glumes
I'm not quite sure what you mean. However, E. vaginatum only ever has one spikelet per stem. All the others have two or more. The glumes are very similar for all four UK species except for E. gracile when they have several nerves in the glume instead of the single nerve which E. vaginatum and the other two species have. The sizes of the glumes are variable and all overlap, however they may offer some help at the extremes of the range of sizes. However there are other, much more obvious features by which it is easy to tell the four species apart. Try Jermy et al, Sedges of the British Isles London:BSBI (2007). There's nothing better and it's essential for anyone seriously interested in sedges.
