Recently, Valentini [Phys. Plasmas {bold 3}, 1459 (1996)] investigated the influence of collisions on the space charge formation and derived a modified Bohm criterion accounting for collisions in the sheath. It is shown that this derivation is wrong and is based on a misinterpretation of the plasma sheath concept. {copyright} {ital 1996 American Institute of Physics.}
