Morphology of the (100) face of zinc cadmium thiocyanate crystal before and after its growth at 30(+/-0.05)degreesC at a supersaturation of 0.087 has been studied. Highlands formed by chains of small growth hillocks generated by spiral dislocation sources and small cavities adjacent to the hillocks have been observed. The small cavities are assumed to result from continuous growth of large hollow channels at the top of the highlands rather than being hollow cores indicative of spiral dislocation growth. Strings of similar cavities are also found at "macrosteps". All highlands and strings of cavities are oriented along the [010] direction, which manifests a strong anisotropic growth at this face associated with the strong PBC bonds along this direction.
