Evolutionary tree for the genera Namibialina and Ramalina (subset of Matrix 1). The tree is a close-up of Figure 6. Values above branches represent the posterior probabilities of support. Table on right side provides further information for all accessions: column 1-4: ß-depsidones (protocetraric acid, salazinic acid, stictic acid, norstictic acid); column 5-8: depsides (divaricatic acid, sekikaic acid, evernic acid, lecanoric acid); column 9: triterpenes; column 10: bourgeanic acid; column 11: unknown fatty acid; greyish colour through columns 1-11 for two accessions (R. complanata and R. crinita) means that no data are available.
