Phylogenetic interrelationships of the orders of flowering plants (AGP, 1998)


"Within the eudicots there is increasing support for a large subgroup with predominantly pentamerous and isomerous flowers, the core eudicots, mainly comprising Caryophyllales, Santalales, Saxifragales, rosids and asterids.  Rosids and asterids each comprise two large subgroups, eurosids I and II and euasterids I and II, also receiving increasing support as monophyletic."

from Figure 1. Phylogenetic interrelationships of the orders of flowering plants, compiled from recent cladistic analyses cited in the text. Jackknife support is given on the branches (a dash for values <50%), first jackknife values from analysis of 545 sequences of the rbcL, atpB, and 18S rDNA genes (D. E. Soltis, M. W. Chase, P. S. Soltis, D. Albach, M. E. Mort, V. Savolainen, M. Zanis, and J. S. Farris, unpublished, in preparation) and second jackknife values from analysis of 2538 rbcL sequences (Källersjö et al., 1998).
