THE COTTAGE GARDENER.

the colour, and the greater the body of air between the 
sides of the pot and the protecting covering, the better 
i it would be. This simple precaution would save from 
| injury many a valuable plant in summer, and would be 
: quite as effectual as placing the plant in a double pot. 
J he reason why plants thrive better in summer, when 
standing in pits, with turf sides, than when standing 
exposed, is chiefly owing to two facts; first, that the 
walls protect the roots from the fierce action of the 
suns-rays; and, secondly, because the temperature is 
more uniform, as the earth wall, Comparatively speaking, 
absorbs and radiates heat slowly. 
CALCEOLARIAS AFFECTED WITH A 
BLACK LEPROSY. 
Many complaints of this have reached me. I men¬ 
tion it prominently here to elicit cause and cure ; as I 
am sorry to say, that whatever my ideas respecting the 
former, I can offer nothing satisfactory as respects the 
latter. The readers of this work are aware that some 
time ago I highly praised the Kentish Hero Calceolaria, 
and I did not say one word too much in its favour, for, 
for. early and late and continuous blooming, few yet will 
beat or equal it; there was, in fine, something like 
Hero worship in all quarters, and, perhaps, none were more 
ardent than myself. Well, I had, in a regular flower- 
garden, in July last year, four as fine beds a.s the eye 
could look upon, but a thunder and hail storm settled 
them for the season Many flowers were knocked off, 
but that was of no consequence, as, if health had con¬ 
tinued, there were plenty to come. But what was 
worse, the fine foliage was riddled by the hail, and from 
all these places a black decomposing gangrene spread, 
until it arrived at the stems, notwithstanding appli¬ 
cations of lime, sulphur, &c., to prevent it. Anxious to 
continue the stock, 1 propagated some earlier than 
usual, as I saw the beds would have to be replaced for 
the autumn ; and though some of these cuttings looked 
pretty sound at first, they kept going and going, from 
the same disease, during the winter and spring, so that 
now I have not got one remaining; although, after 
always planting largely for several years, I generally 
had some hundreds to spare for those who liked it. I 
have now some six small plants in a bed, obtained from 
my neighbour, Mr. Busby, and 1 am glad to say, that 
his stock, as well as several others of my friends, is 
sound, although many others complain of this black 
disease. I have seen some traces of the same disease 
among other Calceolarias, but nothing to signify. I 
never saw any such thing until after the thunder-storm 
in July. Frequently the leaves turn up, as if they were 
infested with green fly, but seldom does the fly appear 
in unison with this black disease. There is one satis¬ 
faction ; in the case of the Hero, the malady seems 
more constitutional than contagious. Every plant 1 
had was more or less injured in July last year. Every 
cutting taken from the soundest part exhibited, even 
when rooted or growing, the same malady, sooner or 
later. These young plants were placed in the immediate 
vicinity of those received from my neighbour, and were 
even planted out with them. These latter are yet free 
from the disease, while the first are all gone. The 
purchasers of this plant had, therefore, better be sure 
that the stock is free from disease. 
CALCEOLARIA SULTAN. 
This is a fine, large, dark Calceolaria, suitable alike 
for pot, balcony, or bed. It is a worthy neighbour of 
the Hero. I confess I was prejudiced against it. It 
has rather a wide opening for the slipper, and I judged 
that the wet would get there and weigh it down. I had 
several kinds and seedlings this season that I expected 
great things from, and beautiful they looked out-of- 
doors until the late rains, but then they were like bare 
poles. The Sultan has been beautiful in beds for a 
month past—evci’, in fact, since the first week in June ; 
and though heavy rains have caused the large flowers 
to bend, the first change of weather elevated them as 
upright as ever. None but the smaller yellow flowers 
have stood the weather so well. There are some good 
things in its vicinity, but every lady seems to see 
nothing else but Sultan. It has excelled the neighbour 
beds of the group. I consider it, as a dark colour, quite 
as indispensable as the Hero was for its orange-bronze. 
Its wide mouth frightened many from enlisting it, as well 
as myself, but first conclusions are frequently not sound 
ones. R- Fish. 
ROSE CLASSIFICATION. 
( Continued from page 203.) 
Class 10.—Climbing Roses. —These, on account of 
their climbing, slender shoots, are easily known. I shall 
include all that have this habit and are used for this 
purpose, dividing them into sections. 
Sec. 1. Boursaidt Roses, a variety of E. multifont .— 
Fast growers and abundant bloomers. Examples are :— 
Amadis, or Crimson; Boursault,dee]) purplish-crimson, 
large, and semi-double. 
Elegans, crimson-purple, streaked with white; very 
showy. 
Gracilis, bright rosy-red, superb, large, and full. 
Sec. 2. Rosa Arvensis, the Ayrshire Rose.—This sec¬ 
tion is remarkable for quick growth, very thorny 
branches, and abundance of bloom. These qualities 
recommend them for covering lofty walls, stems of trees, 
rough banks, or running up pillars, and covering ar¬ 
bours. Examples are:— 
Ayrshire Queen, dark purplish-crimson ; semi-double. 
Dundee Rambler, white, edged with pink; small and 
double. 
Ruga, pale flesh, changing to white; large and double. 
Sec. 3. Rosa sempervirens, Evergreen Rose. This sec¬ 
tion is chiefly remarkable for retaining their dark green 
shining foliage through a great part of winter. In mild 
seasons, and in favoured localities, they are quite ever¬ 
green. They have also the property of blooming in 
large clusters, sometimes as many as fifty in each. There 
are nearly twenty varieties in this section. 1 select the 
following as examples :— 
Alba plena, white, double; large and full. 
Brunonii, bright purple; small, but very showy. 
FeleciU perpetuelle, creamy-white; beautiful, small, 
and full. 
Myrianthus renoncule, blush, edged with rose; im¬ 
mense clusters. 
Spectabile, rosy-lilac; large and double. 
Sec. 4. Rosa Banksia, Banksian Rose.—Distinguished 
by their smooth stems, small bright leaves, and clusters J 
of very small, elegant flowers. Examples are— 
Alba (white), pure white; beautiful, small, and very 
double. 
Lutea (yellow), fine pale yellow. 
Sec. 5.— Rosa multiflora, The Many-flowered Rose.— 
This section may be distinguished by the abundance of 
bloom, combined with extraordinary vigourous growth. 
Unfortunately many of the varieties are rather tender, 
requiring a south wall in a sheltered situation. Ex¬ 
amples are— 
De la Qrifferaie, fine large flowers, of a rosy-carmine 
colour. 
Graulhie, pure white, often tinged with rose; very 
double. 
Superba, bright rose ; large and fine. 
Triomphe de Bayeux, white, with a straw-coloured 
centre ; flowers arranged in flat heads or corymbs.
