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 Roses.—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. Hither 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 ROSES. 
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 or species appear to be.
