Astereaceae

Astereaceae, also known as the Compositae, is the largest family of flowering plants, comprising over 32,000 species in about 1,900 genera. This family is found on every continent except Antarctica. A defining characteristic of Astereaceae is its capitulum, or flower head, which is an inflorescence made up of many small, densely packed florets that often resemble a single flower. These florets can be of two types: ray florets, which are typically elongated and strap-shaped, and disc florets, which are usually tubular and located in the center of the head. The arrangement of these florets and their modifications contribute to the great diversity within the family. Common examples of Astereaceae include sunflowers, daisies, asters, chrysanthemums, and dandelions. Many species are economically important as sources of food, such as sunflowers for oil and seeds, and artichokes. Others are cultivated for their ornamental value, while some have medicinal uses or are considered weeds. The family plays a significant role in ecosystems, providing food and habitat for various insects and other animals.
