Carex x fulva Hybrid Sedge C DD N
This is one of the commonest Sedge hybrids according to Stace and frequently occurs wherever Carex hostiana (Tawny Sedge) and Carex lepidocarpa (Long-stalked Yellow-sedge). We were lucky to have some expert botanists with us on this Wild Flower Society trip as this was a small patch in the middle of acres of tussocky Culm grassland. The utricles (seeds) were empty and quite spongy when compressed - a typical property of hybrid sedges.
Although it is found throughout the British Isles, it tends to be found more in the west.
