The starting definitions of araucarias given in [1] contain some mistakes. We give here new definitions which replace Definitions 2.2, 2.3 and 2.4, Theorem 2.1 and Corollary 2.1. The rest of the paper is based on the characterization of araucarias given in Theorem 1.1 and remains true with these corrections.
