much more developed, if I were not afraid of abusing the patience of the 

 Congress) we can draw the following conclusions : — Certain sections of 

 the Roses cultivated in our gardens appear to have given the highest 

 results of which they are capable. Seed, pure and simple, only produces, 

 by atavism, very slight variations, often inferior to their progenitors. On 

 the other hand, their crosses with each other, from being but little more 

 fertile, seem unable — except in the case of some classes of Hybrid Teas — 

 to produce any varieties very distinct from their parents. It is time then, 

 I think, that Rose-raisers, having now at their disposal new material for 

 hybridisation, should try crosses between types of Roses widely different, 

 as regards form, colour, and habit, from those actually in cultivation in 

 our gardens. There is particularly room for experiments among the old 

 Noisettes, the Yellow Rose, the Berberifolia group, the Banksians, B. 

 pimpmelHfolia, B. bracteata, B. rugosa, B. microphylla, and such like.
