#acanthiflorous

• Acanthiflorous — A plant morphological term used as an adjective to describe a plant whose flowers or inflorescences are equipped with spines, thorns, or sharp rigid bracts. This anatomical characteristic is frequently found in species of the Asteraceae family (such as thistles) or the Acanthaceae family, where the prickly elements surrounding the corolla serve as a protective barrier for reproductive organs against harmful insects and herbivores.
