Summary:A generalized Landau-Ginzburg-de Gennes theory of cholesteric pitch in lyotropic chiral liquid crystals is presented. Using the non-critical order parameter, introduced by Toledano and Figueiredo Neto, the question of pitch dependence on micellar shape is addressed. This extra order parameter accounts for the shape change of the micelles. The predictions agree qualitatively with the unique experimental observations of Lopes and Figueiredo Neto.
