The capitulum is a contracted raceme composed of numerous individual sessile flowers, called florets, all sharing the same receptacle. A set of bracts forms an involucre surrounding the base of the capitulum. These are called "phyllaries", or "involucral bracts". They may simulate the sepals of the pseudanthium.
