ROSA 



ROSA 



Roses," with 160 colored plates (1817-1820). It is 

 quoted below as Red. Ros. As the first edition in folio 

 is found in only very few libraries, the smaller edition 

 is cited in parenthesis by volume, groups and the 

 sequence of the plates, neither pages nor plates being 

 numbered continuously in this edition. 



The economic properties of the Rose are of little im- 

 portance. The most valuable product is attar of Roses, 

 a highly fragrant essential oil. It is chiefly manu- 

 factured in southeast Europe and western Asia from 

 Rosa alba and R. Damascena, and of late this industry 

 has been successfully transplanted to Germany. See 

 Perfumery Gardening, Vol. III. The fruits of some 

 species, especially of R. villosa and R. canina, are 

 made into preserves.
