Common Yellow-sedge (Carex viridula subsp. oedocarpa)

Observation - Common Yellow-sedge (Carex viridula subsp. oedocarpa). Description: This sedge looks like Carex demissa but I understand there are confusion species. (And why has iSpot substituted Carex viridula subsp. oedocarpa for C. demissa?) Edit: Name updated.
