    In this English translation from the original Russian, the authors give a complete description of the \(n\)-vertex trees with precisely \(\ell\) leaves having the maximal number of maximum independent sets. For a fixed \(n\) and \(\ell\), the extremal tree is unique. Further, it is the result of ``merging the endpoints of \(\ell\) simple paths''. The proof of this result comes from a careful and well-written study of the structure of such trees.
