Almost exhaustive book on the French flora, purely factual -n'y expect any anecdote about a particular plant-but the layout is very old, despite the recent reissues. This book deserves a rewrite with a more airy edition, and especially sharper drawings: one sometimes has the impression of dealing with a photocopy of a photocopy of the original design ... Recognition key are sometimes not used, for example when the dichotomous criterion relates to the fruit.
