Lower fem spike (on R) c 1.4 x 0.5 cm

Quite frequent in alkaline flushes or wet places on alkaline soils.

Fruit c 5 mm long.  Male spike c 8-20 mm long x 1.5-2 mm wide.  Female spike c 8-20 mm.

ID: One male spike, 2-3 distantly spaced female spikes, often not much longer than broad.  Female glumes dark brown with green midrib and colourless or pale brown translucent papery edges.  Fruit has several ribs, not just two as in Green-ribbed Sedge.  Fruit tapers upwards into a long notched beak (depth of notch as great as its width).  Bracts of female spikes not long enough to reach stem tip.  Leaves yellowish-green (i.e not bluish-green or dark green), with long terminal parallel-sided section much narrower than the rest of the leaf.

Other features: Beak of fruit minutely toothed (use lens).  Female spikes often male at top.
