“…When analyzed independently, each of the gene regions (trnL-F, trnK, ITS, RPB2) and morphology alone provided little resolution at the tips but supported three major basal clades plus the monophyly of Dimerocostus ϩ Monocostus and Tapeinochilos. Congruence of the three data partitions (chloroplast, nuclear, morphology) could not be rejected by the ILD test (p ϭ 0.1) nor was incongruence detected among nuclear (ITS vs. RPB2; p ϭ 0.15) or among chloroplast (trnK vs. trnL-F; p ϭ 0.08) regions, indicating that phylogenetic signal from the various partitions could not be considered in conflict (but see Dolphin et al 2000). The lack of well-supported resolution for each partition analyzed alone likely contributed to the lack of conflict observed in the results of the ILD test.…”

“…The molecular evolution model used for the ME and ML tree was selected according to the results of Modeltest 3.7 (Posada and Crandall, 1998) with the AIC criterion. Dolphin et al (2000) showed that even when ILD (Farris et al, 1995) tests reveal significant differences between two fragments it is frequently preferable to analyse them together. Thus the two fragments were combined in a single data set.…”

“…However, because interpretation of test results is somewhat unclear and false significance or insignificance can be attributed under certain circumstances (Dolphin et al 2000;Barker and Lutzoni 2002;Yoder et al 2001;Ramirez 2006), and because the ITS and trnL-trnF tree topologies were mostly congruent and observed conflicts were very weakly supported, analysis of the combined data was undertaken. Only the 25 taxa for which data from both regions was available were included, which meant that the representation of most taxa was reduced to one or two individuals.…”
