from the regular fertilising process, as mules or 

 hybrids have been raised from well known pa- 

 rents. 



In England, but few varieties have been ori- 

 ginated ; as the common China rose does not in 

 general ripen its seeds sufficiently for germination. 

 The parents of Brown's Superb Blush, which is 

 an English hybrid, raised by the late Mr. Charles
