A cladistic study of North AmericanCoreopsis (Asteraceae: Heliantheae)

A Phylogenetic Analysis of the Coneflower Genera (Asteraceae: Heliantheae)

“…The consistency index (CI) is 0.615. Higher percentages of homoplasy have been reported for several composite genera [e.g., 50% in Acmella (Jansen 1985), 80% in Montanoa (Funk 1982), and 57% in Coreopsis (Jansen et al 1987)]. A similar consistency index was reported by Panero and Schilling (1988) from a cladistic analysis of Viguiera sect.…”

Phylogeny of Eastern North American Coreopsis (Asteraceae‐Coreopsideae): insights from nuclear and plastid sequences, and comments on character evolution

“…Phylogenetic analyses of morphological characters in the Coreopsideae were not informative in resolving relationships between the two genera (Ryding and Bremer, 1992;Karis and Ryding, 1994;Mesfin Tadesse et al, 2001), but these and other workers have commented that their results provide little or no support for the monophyly of either genus. 1976,1982,1983) and explicit methods (Jansen et al, 1987). The authors thank David Giannasi for field assistance in locating several species in the field, and we thank Ronald Hartman for permission to use specimens in the Rocky Mountain Herbarium as a source of DNA.…”
