A description of the set $X_p$ of all solutions of the trivial Cauchy problem in $L_p, o< p <1$, is presented. The principal result is Theorem 2, which asserts that $X_p$ is a closed subspace of the $p$-Banach space $H_p$ of all curves in $L_p$ that satisfy a Hölder condition of order $p$ and emanate from O relative to the $p$-norm, which is equal to the minimal constant in the Hölder condition.
