Rough Cocklebur (Xanthium strumarium) Achene

Growing at a disturbed forest edge.

This "bur", with its hooked projections, was adapted for seed dispersal in mammalian fur. They easily cling to human clothing as well (as evidenced above)!

Note: Our dog Snorri has a bad habit of getting into these plants, and it is a tedious process to dig them out of his long fur!
