Burs or Burrs, seeds or dry fruits or infructescences of a Burdock plant (Arctium minus), England, UK
A bur (also spelled burr) is a seed or dry fruit or infructescence that has hooks or teeth. The main function of the bur is to spread the seeds of the bur plant, often through epizoochory. The hooks of the bur are used to latch onto fur or fabric, enabling the bur – which contain seeds – to be transported to another location for dispersal. Another use for the spines and hooks are physical protection against herbivores
