Excerpt from An Illustrated Flora of the Northern United States, Canada and the British Possessions, Vol. 1 of 3: From Newfoundland to the Parallel of the Southern Boundary of Virginia, and From the Atlantic Ocean Westward to the 102d Meridian The increased accumulations of material in our largest herbaria, the result of multiplied explorations, and the widely extended interest in the study of our native plants, seem now to justify the endeavor to supply a complete illustrated work adapted to general use. The enterprise, projected by Judge Brown, and maintained and supervised by him throughout, has been diligently prosecuted for the past six years. Its execution has been mainly the work of Dr. Britton. The text, founded upon a careful examination of living or herbarium specimens, has been chiefly prepared by him, with the assistance, however, Of specialists in a few groups who have contributed the descriptions for certain families as stated in the footnotes. The figures also have been drawn by artists under his immediate supervision; except those of most of the grasses, drawn by Mr. Holm, under the eye of Prof. Scribner; while the work in all its parts has been carefully revised by both authors. The keys to the genera and species, based upon a few distinctive characters, will, it is believed, greatly facilitate the determinations.
