Yellowish green sedge in woodland - any idea which one?

Observation - Yellowish green sedge in woodland - any idea which one?. Description: In dampish woodland. Distinctly yellowish-green leaves. Only just beginning to flower, so quite likely not possible to identify it, but it looked totally different to all the sedges I've seen so far this year.
