'Intercalary growth' in a regenerating amphibian limb means that if a distal blastema is grafted to a proximal stump:

#Unit 5. Developmental Biology

the distal blastema grows back, to regenerate proximal elements, then out, to regenerate distal structures.
the stump grows out to regenerate proximal structures, until the positional values of the blastema are produced, at which time the distal blastema takes over and completes outgrowth of distal structures.
the distal blastema grows out, regenerating distal structures, resulting in a limb lacking intermediate structures.
the distal blastema grows proximally, intercalating intermediate structures between it and the stump, then growth stops, resulting in a regenerate lacking distal structures.
