Leaf power powers for bounded values of have bounded clique-width, but this is not true of leaf powers with unbounded exponents. A graph is a 2-leaf power if and only if it is the disjoint union of cliques (i.e., a cluster graph). A graph is a 3-leaf power if and only if it is a (bull,dart,gem)-free chordal graph. Based on this characterization and similar ones, 3-leaf powers can be recognized in linear time. Characterizations of 4-leaf powers are given by and , which also enable linear time recognition. For "k" ≥ 5 the recognition problem of "k"-leaf powers is open, and likewise
