#flatsedge

AKA papyrus sedges, nutsedges, umbrella-sedges and galingales. There are roughly 700 species of flatsedge found worldwide - most grow in shallow, slow moving water. This one was growing on the side of the road, with no sign of standing water.

The "true" papyrus sedge of Ancient Egypt, C. papyrus subsp. hadidii, is now very rare to habitat loss. For a while it was feared extinct. Cyperus rotundus on the other hand is one of the most invasive weeds known, having spread to tropical and temperate regions worldwide.
