Quite tall, on the edge of a bit of bog with lots of Juncus, but the only one I could see.

Definitely Bolboschoenus; it looks fairly robust, so probably B. fluviatilis tho ideally need more detail in order to confirm ( diameter of culm, number of bracts, length spikelet) - not so easy with a distant photo.

Jane i'd disagree. With those huge involucral bracts and long flattened spikelet clusters I would think this is a Cyperus. Cyperus exaltatus would fit the bill.
