The numerous va- 
rieties belonging to 
this section are dis- 
tributed by gardeners 
amongst the Tea, 
Bourbon, Hybrid Per- 
petual, etc., according 
as they favour one or 
the other of these 
groups. But from the

and recrossing which 
they have undergone,

and merely serves as 
a comparative guide 
for the amateur. We

furnishing than receiving pollen—if, at least, we can place any 
confidence in the statements of horticulturists, who affirm that 
these Roses are usually produced pretty faithfully from seed. 
Be this is as it may, it is very possible, as is supposed, that the 
Noisette Rose, R. Noisettiana (fig. 91), is to be attributed to 
a@ cross between the Tea, or Bengal Rose, and R. moschata,
