Abstract
A taxonomist may use rooted trees to depict hierarchical classifications of species belonging to the same family. We look at various properties which might be required of a "coefficient of similarity" to be used to compare the shapes of two such trees. A similarity measure calculated from the number of shared subtrees is found to satisfy these requirements.
