Rosa. Seventy-eight species, and an almost innumerable number of varieties, principally hardy deciduous or evergreen shrubs. To attempt an enumeration, much less a description of all the varieties which they profess to cultivate in Europe, would be an unnecessary waste of space, for the simple reason that many of them are unworthy of preservation, and others vary so slightly that a practiced eye is scarcely able to detect the difference. The Queen of Flowers had at no previous day attained the celebrity and popular favour it now enjoys, and never was it so well worthy that popularity. Ever charming, it is now doubly so from exhibiting its beauty almost without intermission, whilst very many of them yield powerful and delicious perfume. Those who may be resident in remote positions, and whose idea of the rose, pleasing as it may be, is the recollection of it, as it was in bygone years, are far behind the age - nothing, whether it be artificial, or the product of nature assisted by art, has kept more steady pace with the improvements of our day.

The following select varieties in each of the divisions into which by common consent this flower has been divided, are abstracted from the catalogue of the old Landreth nursery, and though they are now certainly among those most to be desired, who can tell how soon many of them may be superseded by more attractive varieties? Whilst speaking of varieties it may not be out of place to remark that great disappointment has been endured by importers of roses from Europe, induced to order by the enticing descriptions in English and continental works: a large majority, it is believed, have fallen short of their transatlantic character, and American florists have not al ways escaped censure for distributing varieties of little worth, when their only fault was reliance on the fidelity of European descriptions.
