bract

thumb|Papery (upper) and leafy bracts on Rhinanthus minor (hay rattle). All the "leaves" in this image are bracts.

In botany, a bract is a modified or specialized leaf, associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves in size, color, shape or texture. They also look different from the parts of the flower, such as the petals or sepals.
