The wide-spreading inflorescence of Rough Flatsedge looks like a fireworks display. The 4-13 spikes are ob-cylindrical (widest at tip) and occur at the ends of very long stalks. It is similar to C. plukenetii, but the spikes are twice as long (or more). It is also similar to C. hystricinus, but differs in the rather scabrous (rough to touch) stems (vs. smooth), per Vascular Plants of North Carolina.
Visit Flora of North America to view their excellent illustration comparing spikes of C. retrofractus to C. hystricinus, C. lancastriensis, C. plukenetii, C. refractus....
