Xanthium strumarium

Cocklebur (Xanthium strumarium) is a coarse annual up to two metres tall, its stem grooved and its alternate leaves roughly triangular, toothed, sometimes cut into three to five lobes and covered in short stiff hairs. The flowerheads are small, the female ones held in a pair of thick spiny bracts that harden into a spindle-shaped burr, hooked all over so that it catches in animal coats and children's hair. It grows wild across Vietnam on waste ground, field banks and roadsides, and is also sown in spring. In late summer and autumn the ripe burrs, or the whole plant with its roots cut away, are dried in sun or kiln.
