bracteole
Quick Summary
A bracteole is a small bract, which is a modified, leaflike structure typically found beneath a flower or inflorescence. In an inflorescence, the bracteole is equivalent to a bract and is located at the base of a flower's stalk (pedicel). These structures can sometimes be mistaken for petals, as seen in plants like poinsettias or dogwoods, where bracts are large and colorful. The term "bracteolate" simply means that a plant part is furnished with bracteoles.1234
