Bracts are leaves in inflorescences that differ in arrangement, colour, size and/or morphology from the foliage-leaves. The notable large white spathe around the inflorescence of Arum – Arum Lily is, for instance, considered as a bract. On the other hand, bracts, especially when supporting bracts, may be small and squamous (e. g. the involucel bracts in the Apiaceae – Carrot family).
