graved, in 1581, ten sorts of roses. In 1620, 

 Bauhin increased the number to nineteen. 



From that period, the study of roses has been 

 unintermittingly pursued, and new species con- 

 stantly established. In 1784, Murray, in an 

 edition of the works of Linnaeus published at 

 Gottingen^ described twenty-one species ; in 

 1797, Willdenow, in a similar work, described 

 thirty-six ; and Persoon, in his Synopsis, 

 forty-six. 



The celebrated Gardeners' Dictionary of Mil- 

 ler, translated into several languages, contains a 

 valuable treatise upon the rose; establishing, 

 in the year 1785, thirty-one species. This work, 

 revised by Professor Martyn of Cambridge, af- 

 fords a detailed account of the varieties culti- 

 vated in Great Britain. A splendid illustrated 

 work by Miss Lawrence, being a folio collec- 

 tion of coloured plates, was published in London 

 about thirty years ago. 



In 1811, the Baron Dumont de Courset, a 

 highly intelligent florist, published a second 

 edition of his work, " Le Botaniste Cultivateur," 

 in which he enumerates thirty-seven species of 

 roses cultivated in his gardens at Courset, near 

 Boulogne-sur-Mer. In the article on Botany 

 of the French Encyclopedia, (written by La- 

 marck and Poiret,) the number of species wa* 

 augmented to sixty-five.
