THE following Catalogue of the hitherto known Plants of North America, native 

 and naturalized, has been compiled from a number of observations made on living 

 plants in Pennsylvania, and on dried specimens received from other parts of North 

 America by the Author. Some plants have been added from botanical books, to 

 distinguish those as not existing a» the Herbarium of the Author: they have been 

 marked with a y. 



Of plants properly foreign, none are received in the Catalogue, if they are not, 

 as it were, naturalized. They are distinguished by the mark C. Many more 

 Plants might have been added, if the specimens received from other parts had been 

 inorc perfect. However, a Catalogue of Plants now known, is a real Desideratum ; 

 and it will be easy to add supplements, especially from the Western parts of North 

 America, where great Discoveries were made by Mess. Clarke and Lewis, and 

 plhers. 



The Catalogue is firintcd in five Columns^ viz* 



1. For the Calyx or Empalement : 



2. For the Corolla or Blossom, its Form and Colour : 



For the Latin Systemaiick Name, distinguished by numbers for the Ge- 

 nus and Species, and the Signs of Duration : 



4. For the English Name : The vulgar name, when known, is added in 



Parenthesis : 



5. For the Place of Growth, and the Time of flowering, chiefly in Penn- 



sylvania, which is two Months later than in Georgia. 

 Opposite to the Name of the Genus, the Fruit is mentioned. 



To give as much as possible, multum in fiarvo, many Abbreviations arc used, 

 Which will be easily understood by any Botanist, as 



Cal. o ph. read Calyx triphyllus. 



3 part. tripartitus. 



3 f. trifidus 

 Gl. 2 valv. 1 fl. 2 11. read Gluma, bivalvis, uniflora, biilora. 

 Cor. 5 pet. 4 ph. 6 fid. read Corolla, pentapetala, leiraphylla, sexGda. 

 M. mascula, male, F. femina, female. 

 11. read iloret. 



II. read llortus, found in Gardens. 



C. cultus, cultivated, or Cicur. naturalized, not native. 



0 . annual, % biennial, % persisting, k fruteseent. 



N. Ebor. read New York, N T . Caes. read Jerseys, et cct. 



The Catalogue was written in 1809 ; the printing began in November, 1812, and 

 was finished the latter end of July, 1813. This will explain, why several Plants 

 now well known, are wanting in the first Classes. The Cryptogamous Plants were, 

 M ilh very f sw exceptions, found in Pcnnsvhanuu
