bracteal

Bracteal refers to or is derived from a bract. Bracts are modified leaves found at the base of a flower or inflorescence. They are typically green and leaf-like, but can also be brightly colored, resembling petals. The primary function of bracts is to protect the developing flower bud, but in some species, they play a role in attracting pollinators. The term "bracteal" is used to describe structures or characteristics that are related to or resemble bracts. For example, a bracteal scale might be a small, scale-like structure that originates from the same tissue as a bract. In botanical descriptions, the term can be used to indicate the presence or nature of bract-like structures. The arrangement, size, and color of bracts can be important diagnostic features for plant identification. Some plants are particularly known for their prominent and showy bracts, which can be mistaken for petals. These bracts often serve the purpose of attracting insects for pollination, effectively acting as an advertisement for the flower.
