Davall's sedge (Carex davalliana) is a small perennial sedge of calcareous wetlands and fens across continental Europe, now extinct in the British Isles. It is dioecious, so male and female flowers grow on separate plants, and it needs wet, lime-rich ground to thrive.

About

Carex davalliana, or Davall's sedge, is a species of sedge found in inland wetlands across continental Europe. It is dioecious, with male and female flowers on separate plants.

Where it grows

The species became extinct across the British Isles in 1852 and has not reestablished since. It was only ever identified at one site in the British Isles (a calcareous mire near Bath, Somerset). It became extinct when the land was drained for building houses.
