Phylogenetic Resolution Within The Tribe Episcieae (Gesneriaceae): Congruence Of Its And Ndhf Sequences From Parsimony And Maximum-Likelihood Analyses, James F. Smith
James F. Smith
Generic relationships within Episcieae were assessed using ITS and ndhF sequences. Previous analyses of this tribe have focused only on ndhF data and have excluded two genera, Rhoogeton and Oerstedina, which are included in this analysis. Data were analyzed using both parsimony and maximum-likelihood methods. Results from partition homogeneity tests imply that the two data sets are significantly incongruent, but when Rhoogeton is removed from the analysis, the data sets are not significantly different. The combined data sets reveal greater strength of relationships within the tribe with the exception of the position of Rhoogeton. Poorly or unresolved relationships based exclusively …
