Greensheathed Sedge, Green-sheath Sedge Carex feta Synonym: Carex straminea var. mixta

A close-up of the inflorescence of what appears to be green-sheath sedge as seen at the south side of the Kelly Unit, Conboy Lake National Refuge..........June 25, 2013. Carex feta is very similar and often found at the same sites. I've based this tentative ID on the greenish inflorescence (as opposed to a silvery inflorescence in Carex feta). I'd want perigynia and a glance at the leaf sheath fronts for a positive ID.
