Phylomatic (Part of Phylocom)

The online software takes your list of taxa, and first tries to match them by genus name to the megatree. Failing that, they are attached by family name. If all the genera appear in the megatree, then that family appears resolved. If even one genus is missing from the megatree, the returned phylogeny portrays a polytomy of genera. Currently, species are not included in the megatree, and species within a genus are always returned as polytomies. (http://www.phylodiversity.net/phylomatic/phylomatic_old.html)
