Flavonoids of Heliantheae s.l.
The tribe Heliantheae is one of the largest and most morphologically variable of Asteraceae. This size and complexity has led to two different subtribal classifications in recent years (Robinson, 1981; Stuessy, 1977), which in turn have stimulated detailed morphological cladistic analyses and discussions of the entire tribe (Karis, 1993b; Karis and Ryding, 1994a,b) and its parts (e.g., Bolick, 1983; Ryding and Bremer, 1992; Karis, 1995; Strother, 1999) plus recent molecular analyses (Panero et al., 1999).
