The coupling of dislocations and ledges was considered in terms of the symmetry of phases which met at an interface. Growth and structural ledges, and various dislocation arrays, were treated. The symmetry, and the absence of long-range strain fields, were alone shown to produce few restrictions on the possible interface structures.
