The interface of a growing smectic phase in a supercooled nematic liquid crystal was studied. A change in the morphology and the side-branching activity was observed with theundercooling. Nonparabolic dendrites with faceted dissymmetric tips were found for smallundercooling. The equilibrium shape of the smectic germ was a rectangle. A drifting of thesmectic objects was observed. The starting tip velocities obey the scaling relation νs - Δ4.
