The established identification key to the flora of Switzerland is now available in a new, updated edition, featuring a proven, lightweight, and field-friendly softcover binding. Almost half of the over 3,500 species listed are illustrated with clear images. The identification key allows for the easy identification of ferns and flowering plants that grow wild or have become wild in Switzerland. Since it also includes neighboring areas of Switzerland, it encompasses not only the majority of the Alpine and Central European flora but also many sub-Mediterranean species. The keys are written in an understandable manner and are clearly presented, with technical terms explained in a special glossary. The book is excellently suited for professional and amateur botanists to take on excursions and for plant identification in educational settings.
