Hybridizes with : Greater Tussock-sedge (Carex paniculata) to produce Carex × boenninghausiana which only occurs in exceedingly few hexads scattered around the British Isles and ireland.

Some similarities to : many other Sedges (Carex spp.) but it is pale-green, and the long gaps between the short flower-spikes gives it away from afar. Remote Sedge flower spikes closer together than does Distant Sedge (Carex distans) but that is grey-green rather than light-green.
