The Erdős‐Sós Conjecture is that a finite graph G with average degree greater than k − 2 contains every tree with k vertices. Theorem 1 is a special case: every k ‐vertex tree of diameter four can be embedded in G . A more technical result, Theorem 2, is obtained by extending the main ideas in the proof of Theorem 1. © 2005 Wiley Periodicals, Inc. J Graph Theory 49: 291–301, 2005
