“…Actinidiaceae take an important position in this respect because the family was placed in Ericales sensu stricto by Dahlgren (1989) and Takhtajan (1997), and in Theales by Cronquist (1981) and Thorne (1992). Cronquist (1981, p. 326) considers Actinidiaceae as ''an early and distinct branch of the Theales, not far removed from the ancestral order Dilleniales and near to the ancestry of the Ericales (sensu stricto).'…”

The balsaminoid Ericales, namely Balsaminaceae, Marcgraviaceae, Tetrameristaceae, and Pellicieraceae have been confidently placed at the base of Ericales, but the relations among these families have been resolved differently in recent analyses. Sister to this basal group is a large polytomy comprising all other families of Ericales, which is associated with short internodes. Because there are more than 13 kb of sequences for a large sampling of representatives, a thorough examination of the available data with novel methods seemed in place. Because of its computational speed, Bayesian phylogenetics allows for the use of parameter-rich models that can accommodate differences in the evolutionary process between partitions in a simultaneous analysis. In addition, there are recently proposed Bayesian strategies of assessing incongruence between partitions. We have applied these methods to the current problems in Ericales phylogeny, taking into account reported pitfalls in Bayesian analysis such as model selection uncertainty. Based on our results we infer several, previously unresolved relationships in the order Ericales. In balsaminoid families, we find that the closest relatives of Balsaminaceae are Marcgraviaceae. In the Ericales polytomy, we find strong support for Pentaphylacaceae sensu APG II as the sister group of Maesaceae. In addition, Symplocaceae receive a position as sister to Theaceae and these families form a monophyletic group together with Styracaceae-Diapensiaceae. At the base of this clade are Actinidiaceae and Clethraceae. The positions of Ebenaceae and Lecythidaceae remain uncertain.

“…It effectively reduces the options for placing Chloranthaceae, a family that has been placed previously with Laurales (Thorne 1992), Piperales (Cronquist 1981), and Canellales (Dahlgren 1989) and that is still uncertain for its phylogenetic affinity. Furthermore, placement of Piperales as sister to Canellales within the magnoliids removes the order from the list of taxa to be considered as potential sister lineages to monocots, as Burger (1977) suggested a close relationship between Piperales and monocots.…”

DNA sequences of nine genes (plastid: atpB, matK, and rbcL; mitochondrial: atp1, matR, mtSSU, and mtLSU; nuclear: 18S and 26S rDNAs) from 100 species of basal angiosperms and gymnosperms were analyzed using parsimony, Bayesian, and maximum likelihood methods. All of these analyses support the following consensus of relationships among basal angiosperms. First, Amborella, Nymphaeaceae, and Austrobaileyales are strongly supported as a basal grade in the angiosperm phylogeny, with either Amborella or Amborella and Nymphaeales as sister to all other angiosperms. An examination of nucleotide substitution patterns of all nine genes ruled out any possibility of analytical artifacts because of RNA editing and GC-content bias in placing these taxa at the base of the angiosperm phylogeny. Second, Magnoliales are sister to Laurales and Piperales are sister to Canellales. These four orders together constitute the magnoliid clade. Finally, the relationships among Ceratophyllum, Chloranthaceae, monocots, magnoliids, and eudicots are resolved in different ways in various analyses, mostly with low support. Our study indicates caution in total evidence approaches in that some of the genes employed (e.g., mtSSU, mtLSU, and nuclear 26S rDNA) added signal that conflicted with the other genes in resolving certain parts of the phylogenetic tree.

“…The orders placed close to the Zingiberales and in which the sister groups of the Zingiberales will most likely be found (Bromeliales, Commelinales; Thorne 1992) all posses this stamen. In the Heliconiaceae, the other family traditionally placed close to the three listed above (the banana group), a member of the outer androecial whorl is replaced by a staminode (Eichler 1875;Kunze 1985;Kress 1990;Kirchoff 1991Kirchoff , 1992.…”
