Résumé : In biology a phylogenetic tree is a classical tool to represent the evolutionary relationship among species. Our main frustration against the classical combinatorial models is related to the chrono- logical aspect that seems not considered by the models. E. g. the Schröder trees do not take into account the time evolution. We develop in this paper a model for phylogenetic trees satisfying in priority two constraints: (1) to take into account the chronological evolution and (2) to be efficient to simulate. Our model is based on some increasingly labeling of Schröder trees.
