Excerpt from Class-Book of Botany: Being Outlines of the Structure, Physiology and Classification of Plants, With a Flora of the United States and CanadaFrom the multiplication of species and genera we have studiously refrained, believing that our books already contain more than Nature will warrant. In the case of any doubtful specimen, which might have served as the basis of a new species, or possibly genus, (had this been our aim), we have always inclined rather to the extension of the limits of some kindred group for its reception, having less apprehension of error in this direction than in the opposite, with all due regard for the permanence of true species. The same principle has compelled us to disallow the claims of many reputed species of the best authors.In the sequence of the Natural Orders, we have, in common with all recent American authors, mainly adopted the arrangement of De Can dolle, - nu arrangement seen, in part, in the Flora of the State of New York, ' by Dr. Torrey. It commences with those Orders supposed to be of the higher rank in organization, and proceeds gradually to the lower, regarding the completeness of the ¿ower and the distinctness of its parts as the general criterion of rank.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
