This book of botany by Eric Grossenbacher is rich of more than 1770 species (560 pages). Eric Grossenbacher carefully noted throughout his career the names of the plants of the Jura Mountains (France and Switzerland). He took special care to continue the work of Charles Krähenbühl by supplementing his famous Répertoire des plantes vasculaires du Jura bernois, published in 1970. Eric Grossenbacher offers us a finished and richly documented work.
