Phylogenetic systematics of Berberidaceae and Ranunculales (Magnoliidae)
Based on a cladistic study employing outgroup comparison and parsimony analysis of 34 genera within Ranunculales, we infer that Berberidaceae, Lardizabalaceae, Menispermaceae, and Ranunculaceae are…
CLADISTICS OF THE MAGNOLIIDAE
These results support many aspects of the strobilar‐flower hypothesis for the origin of the angiosperms, as well as the plesiomorphic character states of woody shrubs with simple, pinnatelyveined leaves.
Ordinal and familial relationships of Ranunculid genera
A morphological-based cladistic analysis was conducted on 116 ingroup taxa and 5 outgroups coded for 109 characters and 192 apomorphic character states. Ranunculid genera are better organized as the…

Generic relationships within Leonticeae (Berberidaceae)
Phenetic analyses of morphological characters of Leonticeae reveal three distinct groups of operational taxonomic units corresponding to genera, which are pheneticlly equidistant from Caulophyllum, which occurs in eastern Asia and eastern North America.
Comparison of Alternative Hypotheses for the Origin of the Angiosperms
- H. Loconte
The development of a phylogenetic system of classification for the flowering plants is dependent on the objective resolution between alternative hypotheses for their origination. Here six hypotheses…
Cladistics of the Spermatophyta
A posteriori consideration of fossil taxa supports the conclusion that data from the fossil record are useful for confirming plesiomorphies of extant taxa.

Gauthier et al. (1988) proposed a means of distinguishing stem lineages from their respective monophyla by developing a hierarchical nomenclature for the fossil record, in contrast to the plesion concept.
