Nutgrass (Cyperus rotundus) Seed Head - Close-Up Identification Guide #3325670 (License: Personal Use)

This image captures the mature inflorescence of Cyperus rotundus, commonly known as nutgrass or purple nutsedge, featuring 5-10 radiating spikelets that form a star-like structure. Each spikelet is densely covered in stiff, retrorse (backward-pointing) bristles, aiding in seed dispersal and making the plant easily identifiable. The pale beige color contrasts sharply with the vibrant green background of grassy foliage.
