Close-up of a burr off a Cocklebur, Xanthium strumarium. One of the interesting facts about it is that the burrs grow straight out, and then recurve after the fruit has matured, ensuring it is only carried away after it is ready to re-seed. Legend has that it serves as the biomimetic basis for the concept of velcro.
