Covering over two dozen fern and half a dozen gymnosperm families, they survey fern species of both ecological and horticultural importance and review such gymnosperm taxa as the conifers (the dominant trees in many forests as well as important timber plants) and cycads, which display significant evolutionary features. In all, the volume assembles 509 species of ferns and fern allies and infraspecific taxa in 70 genera.

This book was released on 2015-06-26 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Flora of the Northern and Middle Sections of the United States, Vol. 1: Or a Systematic Arrangement and Description of All the Plants Hitherto Discovered in the United States North of Virginia The progress of botanical science in the United States has been so rapid during the last few years, that new works, containing the discoveries continually making, are, from time to time, required. The excellent Flora of Mr. Pursh, which appeared in 1814, exhibited all that was then on record, as well as all which the enterprising author himself discovered, relative to North-American botany. Since that time have appeared the "Genera of North-American Plants," by Mr. Nuttall, a work which has contributed more than any other to advance the accurate knowledge of the plants of this country; Mr. Elliott's excellent "Sketch of the Botany of Georgia and South-Carolina;" "Barton's Flora of North-America," besides numerous monographs and miscellaneous observations on North-American plants, published in various scientific journals. A considerable number of our plants have also found their way to Europe, and have there been described and illustrated by the most celebrated botanists of the age. A small proportion, however, of North-American plants, even of those growing in the most explored parts, have yet been attentively examined. Having devoted a number of years to the study of the plants of this country, particularly those of the northern and middle parts of the United States, the author conceived that a Flora embracing this section, would be a proper counter part to the work of Mr. Elliott on the Botany of the Southern States. He accordingly commenced collecting materials for the present work; and, after much labour and care, he at length ventures to submit it to the public. The advantage of local Floras is now generally acknowledged; as their authors, it is presumed, must be better acquainted with the plants of which they treat than with those of a more extensive district; they are the means of recording many facts and observations, and minute descriptions, which could not be introduced into general works; they also increase our knowledge of vegetable geography. It has been the object of the author to bring together all that has hitherto been published on the subjects embraced by this work, and to add such observations as his own opportunities have enabled him to make.
