Is0 -epit axial Growth of n -Oct acosane Cry st als Iso-epitaxial(epi1ayer)growth of n-octarosanc crysi als is reported. The niorphology of the epilaycrs is i n the form of triangular growth islands with or without truncature. Epilayer growth precedes spiral growth mechanism which occurs at medium and low supersaturations, respectively. The occurrence of triangular and truncated rhombic platelets is found to be a inanifestation of growth a t medium supersaturations.
