bur

The Columbia Encyclopedia, Sixth Edition

bur or burr, popular name for fruits that have barbed, pointed, or rough outgrowths. By clinging to the fur or hair of animals and the clothing of man they are transported from the parent plant, often great distances. Some common burs include those of the chestnut, burdock, bur marigold, and cocklebur. Burs are particularly obnoxious to sheep growers because of the difficulty of removing them from wool.
