Summary/Supertree of the Major
Groups of Angiosperms
Summary of current understanding of basal angiosperm relationships
based on topologies of Zanis et al. (2002) and Qiu et al. (1999).
Strict consensus of 16 MP trees obtained in analysis of the 104-taxon
data set. Tree length = 23,864; CI = 0.394; RI = 0.518. Bootstrap values
(obtained by using 200 replicate searches with TBR with MULPARS turned
off) for major clades of angiosperms are indicated above the branches.
A summary of the major groups that occurred in greater than 50% of
the 1000 jackknife replicates; orders and informal names are more or
less those of the APG system (1998). The gymnosperms are not arranged
to reflect relationships, but rather they were collectively specified
as the outgroups without any attempt to estimate which, if any, were
closest to the angiosperms.
