This chapter is designed to teach about biology and distribution of Asteraceae (or Compositae*) in a broad sense so that correlations drawn with flavonoid chemistry in other chapters of the book will be more meaningful. This is a difficult task; so much material on the family exists that it is impossible to present successfully (and succinctly!) all of it on structural, biological, and spatial dimensions in just one short chapter. We have selected information concerning the family that seems pertinent, interesting, and helpful for understanding relationships at different levels of the taxonomic hierarchy.
