fied the adoption of a new section or family. It 
therefore often becomes a difficult matter to know, 
even by those well experienced in such matters, 
how to arrange the varieties correctly, according 
to their respective divisions, and few agree entirely 
as to the location of certain varieties which pro- 
perly belong as much to one class as to another. 
It will be well, therefore, in all cases where 
practicable, to diminish rather than to increase the 
number of families or divisions. 
All Roses may be included in one or other of 
two great divisions, viz., Summer-blooming and 
Perpetual-blooming. The Summer-blooming are 
varieties which bloom only once during the season, 
though they vary as to the duration and time of 
flowering, some commencing earlier and_ lasting 
only a short time in bloom, others commencing 
later and lasting two or three weeks ; thus, with 
a collection of the Summer-blooming Roses, a 
succession of flower may be had for five or six 
weeks, 
The autumnal or perpetual-blooming Roses are 
such as, in the open air, bloom from June till 
November, or with the assistance of glass may 
be had in bloom nearly the whole of the year. 
Roses may be grown in a great variety of forms, 
and their habit and character are such as to admit 
of their being adapted to a variety of purposes 
in the garden. Hence we have what are called 
Standard Roses, Half-standard, Dwarf-standard, 
Dwart, Weeping, Climbing, Pillar or Pole Roses, 
Pot Roses, &e.
