Flower key inflorescences – some species of flowering plants have solitary flowers but the majority have flower clusters that are called inflorescences. Some families have easily recognised inflorescences. For example in the Daisy family, the inflorescence is called a capitulum and consists of a flat head of small, closely packed stalkless flowers called florets. It and other easily recognised inflorescences are shown here along with the families in which they are found.
