TARIETIES DESCRIBED. 31 



ance of bloom, but they never put forth secondary 

 or autumnal flowers. Tliis is a most peculiarly 

 distinguisliing trait, and an interesting fact. 

 Impregnate a Bourbon, China, or Noisette rose, 

 all abundant autuninal bloomers, with the farina 

 of a French or Provence rose, and you entirely 

 take away the tendency to autumnal blooming in 

 their offspring. They will grow vigorously all 

 the autumn, and give a long, but not a secondcmj 

 series of flowers. Some of these hybrid China 

 roses produce seed abundantly, which is rather a 

 remarkable feature, as so few hybrid plants are 

 fertile. 



Hybrids produced from the French rose im- 

 pregnated with the China rose are not so hardy 

 and vigorous as those of which the China rose is 

 the female parent ; but, perhaps, this is an 

 assertion scarcely borne out by facts, for the 

 exceptions are numerous, and, like many other 

 variations in roses and plants in general, seem to 

 bid defiance to systematic calculations. By some 

 cultivators the roses of this division have been 

 much more divided than in my catalogue, forming 

 ' Hybrid Noisettes,' ' Hybrid Bourbons,' &c. &c. ; 

 but as these all owe their origin to the common 

 China rose, their offspring may w^ith justice be 

 called Hybrid China roses. I liave, however, 

 found the Hybrid Bourbon roses distinct in their 

 characters, and they now form a group, or division, 

 in the catalogue.
