Synoptical Flora of North America. 



ISSUED FKOM THE 



HERBARIUM OF HARVARD UNIVERSITY. 



A concise and critical treatment o£ the Flowering 

 Plants of North America, with clear descriptions, syn- 

 onymy, bibliography, and geographic range of the species 

 and varieties, growing w^ithout cultivation on this con- 

 tinent, north of Mexico ; also ordinal, generic, and 

 specific keys to facilitate the identification of the plants 

 included. 



Of this extended treatise Professor Asa Gray published, 

 in 1878 and 1884, two parts including all the Gamopetalous 

 Orders. These parts, reissued in 1886 by the Smithsonian Insti- 

 tution, and amounting to nearly 1,000 pages, imperial octavo, 

 may be had for $2.50 from the Cambridge Botanical Supply 

 Company. For some time before his death Professor Gray, con- 

 tinuing the work, was engaged in monographing the earlier 

 Polypetalous Orders. After the death of Professor Gray the 

 preparation of the Synoptical Flora was carried on by Dr. 

 Sereno Watson, and then by his successor, Dr. B. L. Robinson. 

 Following the original plan of the Flora, the treatment of the 

 Polypetalous Orders will form, when completed. Volume I, Part 1.
