This book presents 64 portraits of orchids, for the main part wild, photographed in close up, on a black background and of the front, to put forward their incredible beauty, diversity and perfection, wich give the feeling that we doubtless have to deal with a summit of the evolution. Every flower is a work of art created by the nature and its million years of co-evolution with insects. As wrote Konrad Lorenz " the interest for the nature often begins with fascination ", it is the idea of this book. It is also to inform the reader about the universe of orchids. Every portraits is indeed the pretext of a botanical and historic information, told by Frédéric Pautz, director of the botanical garden of Nancy.
