Iso‐epitaxial growth (twinning, parallel growth) of sucrose, β‐succinic acid, anthraquinone and isatin can be explained by a good fit of the energetic structures of both partners. The symmetry operations result from the pseudo‐symmetries of the reciprocal crystals. In all cases possible planes favoured for the formation of twins or parallel grown individuals can be predicted. Heteroepitaxial growth of β‐succinic acid, hexachlorobenzene, anthraquinone and isatin on (100)‐oriented sucrose has been observed. It is possible to explain the growth mechanisms by symmetry considerations of the energetic structures.
