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D. Albach, M. E. Mort, V. Savolainen, M. Zanis, and J. S. Farris, unpublished,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).
