The most conspicuous character of the family is the grouping of the flowers into a compact head, which is surrounded by bracts forming the structure called involucre {Fig. 44-6). The flowers are epigynous, the corolla is usually tubular or strap-shaped, and the five stamens are in- serted on the corolla and usually have their anthers united in a tube around the style.
