This issue of the bulletin is an revised and expanded second edition of the identification keys originally published in Bulletin Special No. 1 in 1974 under the title "Clés de Détermination des Bryophytes de la Région Poitou-Charentes-Vendée". New species have been described since, and so the title of this new edition has changed to reflect the bigger area now considered. There are three genus-level identification keys for Hepatica, and acrocarp and pleurocarp mosses.
