"The rediscovery Botanical" is exposed to both didactic and complete, that deserves to be included in any library. It is relatively well documented, systematic elements are discussed and the author offers us a fairly general view of the plant world. The bulk of the book, however, remains devoted to angiosperms (flowering plants). Reading is a joy, especially as such initiatives are rare botanical (a discipline that lends itself perfectly yet). This document is useful for anyone who wants to address, or rediscover, the basics of botany.
