Very good support to the discovery, simple and precise in his descriptions. The format is chosen, it fit in a large pocket pants like those side "carpenter", ideal for the ride. The plastic around offers effective protection. Very pleasant to browse. The presentation is clear, the classification procedure accessible to novices including myself, since based on the colors and then the number of petals. Hard not to stop every 1 meter to try to discover all these plants around us.
