N2 - We develop and study two distance metrics for area cladograms (leaf-labeled trees where many leaves can share the same label): the edge contract and- refine metric and the MAAC distance metric. We demonstrate that in contrast to phylogenies, the contract-and-refine distance between two area cladograms is not identical to the character encoding distance, and the latter is not a metric. We present a polynomial time algorithm to compute the MAAC distance, based on a polynomial-time algorithm for computing the largest common pruned subtree of two area cladograms. We also describe a linear time algorithm to decide if two area cladograms are identical.
