Twinning by '''reticular polyholohedry''' is a special case of [[twinning by reticular merohedry]] that occurs when the [[twin lattice]] has the same point group as the lattice of the individual but at least one of its symmetry elements is differently oriented in space.

When the point group of the [[twin lattice]] is only close to that of the individual lattice one speaks of '''twinning by reticular pseudopolyholohedry''', which corresponds to non-zero [[twin obliquity]].
