to assist the ordinary tender annuals in ornamenting that depart¬ 
ment, which they will do most effectually, the bright blue blossoms 
having a fine effect; if placed in the open ground, the pots may be 
plunged entirely out of sight, and if it be a warm and somewhat 
sheltered spot the plants will grow and flower most abundantly ; 
an advantage is however possessed by those grown under glass, 
inasmuch as their delicate foliage is preserved from injury, while 
those exposed to the action of the weather occasionally suffer in 
this respect. In the house, too, they begin to seed rather earlier, 
and thus a supply for the next season is secured, while those un¬ 
protected, being subject to the vicissitudes of the weather, are 
often growing to a late period, and unless taken up before the 
cold of autumn overtakes them, do not perfect their seeds at all. 
Such plants should be removed to the greenhouse or a cold frame 
about the middle of September, when, with a little nursing, they 
will continue vigorous till the end of their existence is attained 
and reproduction made certain. 
As the plant may not be known to all your readers, I will at¬ 
tempt a brief description: it is a branching, suffruticose plant, 
attaining about two feet in height, moderately clothed with rather 
small foliage of a bright pleasing green, and abundantly armed 
with spines in every part; the brilliant cerulean blue flowers are 
numerously produced near the points of the branches ; they are 
of the composite order, about half an inch in diameter, and con¬ 
tinue in perfection a long time; indeed, I am told that when 
nicely dried they retain their colour for several months. 
In the event of the plant failing to produce perfect seeds, it 
may be increased from cuttings of half-ripened wood taken in 
autumn, and struck under a handglass; the little plants thus ob¬ 
tained may be kept through the winter in store pots, on a light 
warm shelf in the greenhouse, and in the following spring will 
require the treatment of seedlings.

THE CLASSIFICATION OF ROSES. 
We have lately received from Mr. W. Haslam, Nurseryman of 
Epping, a Catalogue of the Roses he cultivates, arranged in a 
manner which certainly deserves notice. In the ordinary classifi¬ 
cation of these flowers, artificial terms are employed, which, like
