bracteatum

Bracteatum is a term used in botany to refer to a modified leaf that is often brightly colored and surrounds a flower or inflorescence. These structures are distinct from true petals, which are typically part of the corolla, and sepals, which form the calyx. Bracteates are commonly found in a variety of plant families, often serving to attract pollinators by mimicking the appearance of petals. Their shape, size, and coloration can vary widely depending on the species. In some cases, bracteates may be very small and inconspicuous, while in others they can be large and prominent, even being mistaken for petals themselves. The presence and characteristics of bracteates are often used as diagnostic features in plant identification. For example, the brightly colored "petals" of the poinsettia are actually specialized bracteates, while the true flowers are small and located at the center of the colorful display. Similarly, in many species of orchids and bromeliads, bracteates play a crucial role in attracting pollinators. The term itself derives from the Latin word "bractea," meaning a thin metal plate, likely alluding to the often thin and sometimes metallic-looking nature of these modified leaves.
