The Manual of the Botany of the Northern United States

The Manual of the Botany of the Northern United States - Including the District East of the Mississippi and North of North Carolina and Tennessee

The first edition of Gray's Manual was published in 1848. It was to a great extent rewritten and its range extended in 1856, and it was again largely rewritten in 1867. The great advances that have since been made in systematic botany and in the knowledge of our flora have for several years past made another revision desirable, which Dr. Gray before his death was purposing to undertake. The present editors, acting to the best of their ability in his stead, have endeavored throughout to follow his methods and views. The original plan, so long retained by Dr. Gray and so generally approved, has been closely adhered to, the characters and descriptions of the last edition have been left essentially unchanged so far as possible, and in the numerous alterations and additions that have been considered necessary or advisable, his conclusions and principles have governed in every matter of importance, so far as they could be known. The effort especially has been to maintain that high standard of excellence which has always made the Manual an authority among botanists. In the treatment of the genera and species, Gray's Synoptical Flora has been made the basis in the revision of the Gamopetalous Orders, and the manuscript in continuation of that work, so far as prepared, for the Polypetalous Orders which precede Leguminos (excepting Nuphar, the Crucifer, Caryophyllace, Vitis, and the small Orders numbered 18, 22, 23, 2527, and 29). The genus Salix has been rewritten for this edition by M.S. Bebb, Esq., the genus Carex by Prof. L.H. Bailey, and the Ferns and allied orders by Prof. D.C. Eaton. For the rest, all known available sources of information have been made use of, and much willing help has been received from botanists in all parts of our territory. ......Buy Now (To Read More)
