An Illustrated Flora Of The Northern United States, Canada And The British Possessions Vol2 | by Nathaniel Lord Britton, Addison Brown



To all botanical students, a complete illustrated manual is of the greatest service; always useful, often indispensable. The doubts and difficulties that are apt to attend the best written descriptions will often be instantly solved by figures addressed to the eye. The greatest stimulus, moreover, to observation and study, is a clear and intelligible guide; and among the aids to botanical enquiry, a complete illustrated handbook is one of the chief. Thousands of the lovers of plants, on the other hand, who are not botanists and are not familiar with botanical terms or the methods of botanical analysis, will find in the illustrations of a complete work the readiest means of comparison and identification of the plants that .grow around them; and through the accompanying descriptions they will at the same time acquire a familiarity with botanical language. By these facilities, not only is the study of our native plants stimulated and widened among all classes, but the enjoyment, the knowledge and the scientific progress derivable from these studies are proportionately increased.
