A sedge, I'm sure, but a very short one - only about 8-9 cm.
No interactions present.
Most sedges have tringular (triquetrous) stems most rushes don't they are circular in section.
"Sedges have edges"
Many wood rushes (Luzula) have relatively long rather silky hairs on the leaves - this is unusual in sedges
Thank you so much for all the info!
I knew about the triangular stems of sedges, but could not really tell whether this was.
It obviously is not! Will research it more - I had a feeling that the long hairs on the leaves might help ID. Thank you
