Bract

Bract (/brækt/), from the Latin bractea, meaning a thin piece of metal, is a term used in botany. It refers to a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis, or cone scale. Bracts are often different from foliage leaves and may be smaller, larger, or of a different color, shape, or texture.

Etymology

The term bract is derived from the Latin bractea, which means a thin piece of metal. This is likely a reference to the often thin, leaf-like nature of bracts.
