  The Jacobian elliptic functions are generalized to functions including the
generalized trigonometric functions. The paper deals with the basis property of
the sequence of generalized Jacobian elliptic functions in any Lebesgue space.
In particular, it is shown that the sequence of the classical Jacobian elliptic
functions is a basis in any Lebesgue space if the modulus $k$ satisfies $0 \le
k \le 0.99$.
