Phylogeny of Moraea showing reconstructed shifts in flowering duration and distribution under an ML model. All species are in the genus Moraea except where otherwise indicated. Coloured balls at terminals indicate the flowering duration of species, while equivalent coloured pie diagrams at each internal node depict the proportional likelihood for different flowering durations. One month, white; 2 months, blue; 3 months, red; 4 months, green; 8 months, black. Nodes reaching the threshold of two log-likelihood units separating the flowering duration of highest likelihood from alternative flowering durations are marked with an asterisk. Bars attached to the left side of nodes indicate significant support (two log-likelihood units separation) for a reconstructed presence in the west; those to the right side of nodes indicate significant support for a reconstructed presence in the east. Internal nodes with no horizontal bars are those for which the reconstructed distribution is not significantly supported. A vertical bar below a node indicates 80-100% bootstrap support; a bar above the node indicates 50-79% bootstrap support; no vertical bar indicates 0-49% bootstrap support.
