Description
Greater burdock (Arctium lappa) burrs. These burrs contain individual fruits (achenes), attached by a papery bract (modified leaf). The end of each bract is hooked, which enables them to become attached to the fur of passing animals, or in human clothing, thus aiding the dispersal of the burr.
