NATIONAL ROSE CONFERENCE. 



201 



The subject of decorative roses then may be briefly summed 

 up as follows : 



Only employ for particular purposes varieties well adapted 

 thereto. 



In the case of groups or masses of dwarf roses in beds — 



(1) Plant many plants of few varieties ; 



(2) Cultivate as highly, prune, disbud, and keep clear 



from insects, &c, as if every bloom were to be 



required for exhibition. 

 Then a display of bloom will ensue, well deserving of the 

 epithet decorative, and likely to be maintained more or less 

 throughout the season. 



ON ROSA POLYANTHA, SIEB. & ZUCC,, A8 A 

 STOCK FOR BUDDING. 



By M. Viviand-Mokel, of Lyons. 



Rosa polyantha, Sieb. & Zucc, was introduced into cultivation 

 in Europe about the year 1860. It was named B. thyrsifloraby 

 Leroy, B. intermedia by Carriere, and B. Vichura by Karl Koch. 

 A little later on it was discovered that the newly introduced 

 species had been previously made the object of study by Siebold 

 and Zuccarini, who had conferred upon it the name which it 

 bears in the title of this note, but several rhodologists, amongst 

 others .the eminent M. F. Crepin, think it referable purely and 

 simply to the B. multiflora, Thimb., known only up to that 

 time in gardens in the double-flowered condition, and of which 

 this form was thought to be the type bearing single flowers, or 

 at least a variety of this type. [See p. 218.] 



As I am desirous simply of calling the attention of English 

 rosarians and amateurs to the value of the polyantha rose as a 

 stock on which to bud other garden roses, I shall in this note 

 only speak on this question, and I will leave others to determine 

 if Bosci polyantlia is a specific type or a mere variety. 



I shall for the present, for the sake of convenience, use the 

 name of Rosa polyeintha, as by that title this plant is universally 

 known. In 1880 a skilful horticulturist of Lyons, M. Alegatiere,
