What you need to do is go back and get close up pictures of
1) Male glumes which should be rounded like this

not pointed like this

2) The leaves have air-filled tubes (aerenchyma) with cross-walls or diaphragms at intervals dividing them into sections. See last mentioned URL. Cut the stem near the base and peel back a leaf to reveal the ligule area. Get the Carex BSBI Plant Crib (PDF freely available from website) to check dimensions.
