A besom is a bundle of twigs, bound to the end of a staff, and used for brushing or sweeping. It was the medieval precursor of the modern household broom, and is sometimes called a “birch-broom”; but it should never be blazoned simply as a “broom”, as that term is used in heraldry for the broom plant or planta genista. The besom is a period charge, found in the arms of Brome, c.1500 [DBA2 315]; it has its straws to chief by default. For related charges, see brush.
