FIGURE 5 in The end of a mystery: transferring Streptostachys robusta to Ichnanthus (Poaceae, Paspaleae) based on DNA sequences, morphology and leaf anatomy
FIGURE 5. Bayesian consensus tree resulting from the combined (ndhF and ITS) analysis. Bayesian posterior probabilities> 0.5 and Maximum Likelihood bootstrap support values> 50% are reported above and below branches, respectively. Ichnanthus robustus is highlighted in bold, followed by a bracket.
FIGURE 4 in The end of a mystery: transferring Streptostachys robusta to Ichnanthus (Poaceae, Paspaleae) based on DNA sequences, morphology and leaf anatomy
FIGURE 4. Part of the trees resulting from the Bayesian and Maximum Likelihood (ML) individual analyses representing the Ichnanthus clade. Bayesian posterior probabilities> 0.5 and ML bootstrap support values> 50% are reported below branches. A. ndhF Bayesian consensus tree; B. ndhF ML tree; C. ITS Bayesian consensus tree; D. ITS ML tree. Ichnanthus robustus is highlighted in bold, followed by a bracket. The accession followed by an asterisk was identified as Ichnanthus sp. BA in Silva et al. (2015b; voucher: Oliveira et al. 1216).
