Book particularly useful and interesting, both for the beginner and for the experienced orchid orchidologue. Perfect book to be on the ground by its small size and light weight, significant details for the comfort of the naturalist. We particularly appreciate the distribution of cards, a simple look, will see if the plant that has been identified is present in the geographical area concerned. Identification keys are very pleasant to deal with in their eyes, a clipped flower that helps to confirm the identification.
