Dig deeper at SERNEC, a consortium of southeastern herbaria.
One of the more "handsome" graminoids of dry sandhills habitats, with a wide-spreading inflorescence that looks like a fireworks display. The 5-10 spikes are obovoid and occur at the ends of very long stalks. Similar in gestalt to C. retrofractus and C. hystricinus, but it differs in its very short spikes (half as long). Read more at Vascular Plants of North Carolina.
Visit Flora of North America to view their excellent illustration comparing spikes of C. plukenetii to C. hystricinus, C. lancastriensis, C. refractus, C. retrofractus....
