Some may be surprised by the volume, as it is a 'recovery' of an edition that does not date from yesterday ... Gentlemen Layens Bonnier and produced in their time, many books on botany . So when some buyers find that the drawings are barely legible, you soon realize that they have not had the chance to have the hands (as I had when I was in high school, there are some time ...) with original editions; they could see that the current issue is worthy of its "older"! Good job then. And if they really want to see remarkable flora, Bonnier and Layens always, I recommend them great flora several large full-page illustrated volumes. But there is no longer a flora "pocket"!
