title: Comment on "theory for the bending anisotropy of lipid membranes and tubule formation".
abstract: We point out that the mechanism proposed by Chen [Phys. Rev. E 59, 6192 (1999)] for the stabilization of tubular vesicles via bending anisotropy and edge tension cannot be applied to symmetric bilayers. Other possible mechanisms are reviewed, with special emphasis on one involving a nematic order of the surfactant polar heads.
