Flavonoids at Infraspecific Levels

  • Bruce A. Bohm
  • Tod F. Stuessy


In this chapter we discuss patterns of flavonoid occurrence at the subspecific and varietal levels. There is no general agreement on how these two ranks should be used (e.g., Hamilton and Reichard, 1992), and we will not comment on this aspect of infraspecific taxonomy. For a detailed discussion see Stuessy (1990). Our sole interest here is to document the use of flavonoids at these levels. We also include a few examples of differences that have been reported among cultivars. These are treated together at the end of this chapter.
