  For an autonomous system the symmetries of the Lagrangian are embedded in the
symmetries of the differential equation. Recently, it has been found that the
modified Emden-type equations follow from non-standard Lagrangian functions
which involve neither the kinetic energy term nor the potential function. By
working with one such Lagrangian we have calculated the Lagrangian symmetries
and explicitly demonstrated that, as in the case of standard Lagrangian
functions, the variational symmetries of the non-standard Lagrangian are also
included in the Lie symmetries of the differential equation.
