Assume that $k$ is a field of characteristic different from 2. We show that if $\varGamma $ is a strongly simply connected $k$-algebra of non-polynomial growth, then there exists a special family of pointed $\varGamma $-modules, called an independent pair of dense chains of pointed modules. Then it follows by a result of Ziegler that $\varGamma $ admits a super-decomposable pure-injective module if $k$ is a countable field.
