DESCRIPTIVE LIST OF FLOWERING SHRUBS. 451 



suckers from the stocks on which his imported Roses 

 were budded. He had planted them out, supposing they 

 were on their own roots, and had not perceived the neces- 

 sity of keeping down the suckers. 



Tree Hoses. The Tree Rose is a beautiful object when 

 in bloom. It is formed by budding the desired variety 

 upon a standard, some four or five feet in height, gener- 

 ally the Dog Rose, as it is called in France, or the Eglan- 

 tine. Many have been imported from France, and succeed 

 well the first or second year ; but from some cause they 

 soon die. Either the severity of our winters, or our pow- 

 erful summer's sun, causes their death. 



New varieties are produced from seed raised from flow- 

 ers, which have been crossed with others of opposite 

 characters ; but none but amateurs will attempt this, so 

 this mode of propagation will not be dwelt upon. 



Of the diseases of the Rose, and of the insects that in- 

 fest it, we shall have something to say in another place. 



GARDEN CLASSIFICATION OF KOSES. 



On the subject of Classification of Roses, there has 

 been much difficulty and confusion among amateurs ; and 

 even Rivers himself, one of the most correct of Rose 

 amateurs in England, remarks: "Within the last ten 

 years, how many plants have been named and unnamed, 

 classed and unclassed! Professor A. placing it here, and 

 Dr. B. placing it there ! I can almost imagine Dame 

 Nature laughing in her sleeve, when our philosophers are 

 thus puzzled. Well, so it is, in a measure, with Roses ; a 

 variety has often equal claims on two classes. First im- 

 pressions have placed it in one, and there rival amateurs 

 should let it remain." 



We are pleased with Mr. Parsons' classification, as be- 

 ing the most simple of any we have seen, and also as 

 distinctive as possible, in a family so intermixed as the dif- 

 ferent varieties cr species appear to be.
