Phylomatic (http://www.phylodiversity.net/phylomatic) is an online phylogenetic query tool where users submit a list of taxa (e.g. from an ecological community), with modern family and genus names, and which returns a phylogenetic hypothesis for the relationships among taxa. Any set of stored phylogenies, or a user‐supplied one, can be chosen as the basis for the returned phylogeny, and several output formats for the tree can be selected. Currently, the source databases cover seed plants.
