Arctium is a genus of biennial plants commonly known as burdock, family Asteraceae. [3] Native to Europe and Asia, several species have been widely introduced worldwide. [4] Burdock's clinging properties, in addition to providing an excellent mechanism for seed dispersal, led to the invention of the hook and loop fastener.
Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
A bur (also spelled burr) [1] 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 ...

The patterns of seed dispersal are determined in large part by the specific dispersal mechanism, and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals.

More than one dispersal vector (abiotic or biotic) is thought to be involved in the majority of seed dispersal events (on average 2.15 dispersal vectors in Dutch ecosystems). [2] Seeds may be transported in turn by various animal or abiotic mechanisms such as wind or water. [1] [3]
