      In addition, the floral morphological diversification in Petrocosmea involves several evolutionary phenomena, i.e. evolutionary successive specialization from clade A to clade C, reversal from clade C to clade E as well as within clade C, parallel evolution reflected by the parallel branches switching to moderate zygomorphy or almost actinomorphy in clade C, and convergent evolution demonstrated by floral similarity between some branches in clades C and E.
