Fasciation in a woolly chamomile flower head (Anthemis tomentosa). Fasiciation is a condition in which the growing tip (apical meristem) of a plant becomes elongated,producing flattened,broadened or contorted tissue. It may be caused by a genetic mutation in the meristematic cells,bacterial infection or insect attack. It is also initiated by mechanical or chemical means,such as damage from frost action or hoeing.
