1 1 6 Phytologia (Dec 2004) 86(3) NEW SUPERTRIBES, HELIANTHODAE AND SENECIONODAE, FOR THE SUBFAMILY ASTEROIDEAE (ASTERACEAE) Harold Robinson Department of Botany; National Museum of Natural History, P.O. Box 37012, Smithsonian Institution, Washington DC, 20013-7012. ABSTRACT Three supertribes are recognized in the subfamily Asteroideae of the Asteraceae; two new supertribes, Helianthodae and Senecionodae, and the typical supertribe Asterodae. KEY WORDS: Subfamily Asteroideae, supertribes, Asterodae, Helianthodae, Senecionodae. DNA studies in the Asteraceae have reached the point where the main elements of the family have been mostly resolved. Two papers (Panero and Funk 2002; Baldwin et al. 2002) have already made taxonomic changes needed to accommodate some of the new findings. The present paper is restricted to providing needed new major taxonomic groupings for the subfamily Asteroideae. The main divisions in the subfamily are presently the tribes, but these are obviously grouped into larger units below the subfamily level. There has been some discussion of merging well-established tribes, such as the Eupatorieae and Heliantheae, to represent these larger groupings. Reducing the number of hierarchical strata in the taxonomy of a large complex family such as the Asteraceae is not considered here as a viable option. The solution offered here is to adopt a scarcely used but functional category to increase the number of strata in the classification by adding the supertribe. The three-supertribe system for the subfamily Asteroideae adopted here includes the typical supertribe Asterodae and the new supertribes Helianthodae and Senecionodae.
