Matching coalescent histories. (A) A matching coalescent history. (B) A mapping from the internal nodes of a tree to its branches that does not satisfy condition (a). Leaf B is descended from node k but does not descend from branch h(k). (C) A mapping from the internal nodes of a tree to its internal branches that does not satisfy condition (b). Node k2 is descended from node k1, but branch h(k2) is strictly ancestral to branch h(k1).
