THE ROSE. Rosa. 
Du Hamel observes that “Nature 
appears scarcely to have placed any 
limit between the different species of 
the rose; and, if it is already very 
difficult to define the wild species, 
which have not yet been modified by 
culture, it is almost impossible to 
refer to their original type the numer¬ 
ous varieties which culture has made 
in the flowers of species already so 
nearly resembling each other/’ To 
the ordinary amateur the great num¬ 
ber of divisions among cultivated 
roses into classes and sub-classes, 
by which professional florists en¬ 
deavor to facilitate a knowledge of 
the different sorts of roses, some¬ 
times serves rather to make the 
confusion worse confounded. The distinctions which seem simple 
enough, and quite necessary to professional florists, who have exam¬ 
ples of all sorts constantly before their eyes, is a bewildering mass 
of floral lore, quite embarrassing to the amateurs for whom one 
or two dozen of the best varieties of roses will do as well as a 
thousand. The author of a recent horticultural work, after enumer¬ 
ating we know not how many classes of roses, closes the chapter 
by condensing the results of his experience into a “ select list ” 
of upwards of two hundred varieties I A generosity scarcely ex¬ 
ceeded by the nursery catalogues. 
A plan now adopted by many nurserymen, and recommended 
by Francis Parkman in his excellent treatise entitled “ The Book 
of Roses,” is to arrange roses in two great divisions, viz: the first 
division embracing all roses, whether hardy or tender, which bloom 
in June, and not afterwards; the second division embracing all 
which bloom more than- once in a season.
