even light and gravelly, so much the better. The 
flowers of the species under notice vary in colour in 
different individuals, but they are generally of a 
deep reddish purple and produced in great abund¬ 
ance around the top of the previous year s wood 
The apical bud, however, contains no flowers, but 
grows into a leafy shoot about the time the 
corymbs of bloom open. This as well as several 
other species of Kalmia are useful for planting 
round the margins of large beds or shrubbery 
borders. It is a native of Canada, perfectly hardy, 
and flowers with greater freedom even in the north 
than K. latifolia. 
CAMPANULA G F. WILSON. 
This has all the appearance of being a hybrid 
between C. pulla and C. turbinata or C. Raineri. 
The habit of the plant is very dwarf, being only 3 in. 
to 5 in., and the flower stems are very numerous, 
terminating in a single bell-shaped bloom inter¬ 
mediate in size and colour between the above- 
mentioned species. The leaves are small and ovate, 
or the upper ones are lanceolate; in the early part 
of the season they assume quite a yellow hue, but 
become of a uniform green later on. The flowers 
are bluish-purple, and sufficiently large to render the 
plant suitable and highly ornamental in good sized 
clumps upon rockwork. 
CAMPANULA RAINERI. 
Bellflowers are very numerous at this season ot 
the year, and that under notice is a very choice one 
in its way owing to its dwarf habit and relatively 
large flowers. In exposed and relatively dry situa¬ 
tions, C. Raineri usually does not exceed 2 in. or 
3 in. in height, but in rich, light soil, kept moderately 
moist, those heights are doubled, an advantage that 
is seen in the greater number of flowers. When 
very dwarf each stem produces one flower only, but 
as it gets tall and strong, several branches are 
developed, each producing a flower of a deep bluish- 
purple, similar in shape to those of C. turbinata, but 
not quite so large. The leaves are ovate and smaller 
than those of the last-named species. The plant is 
eminently adapted for rockwork, as are all the dwarf 
growing species. That under notice is flowering with 
Messrs. J. Laing & Sons, Forest Hill. 
THE ROCK SOAPWORT. 
As Saponaria officinalis in the single or double state 
is useful for the herbaceous border, and S. calabrica 
for the annual border or even summer flower bedding, 
so S. ocymoides differs from all of them in being 
adapted for creeping over the ledges of rockwork. 
It varies considerably in the colous of its flowers, 
and there is a variety in the nursery of Messrs. J. 
Laing & Sons, Forest Hill, grown under the name of 
S. o. splendidissima, which is notable for the rich 
dark hue of its flowers. They are larger than the 
type and of a rich rose-purple. When planted on 
rockwork the stems trail on the ground and flower 
from May to August so long as they are making fresh 
growth. 
ACHILLEA SERRATA. 
The habit and general appearance of this herbaceous 
subject remind one of the British A. Ptarmica, but 
whereas the leaves of the latter are very finely 
serrate, those of the plant under notice are deeply 
serrated, in fact almost pinnatifid. The flowers are 
white and produced in small corymbs terminating 
the stems and branches. It grows usually about 
18 in. high, and is therefore suitable for the second 
line of the herbaceous border. There is a double 
form in the nursery of Messrs. J Laing & Sons, 
Forest Hill, which would be useful in the cut state 
in the same way as the double form of A. Ptarmica. 
The plant is of the easiest culture and increase. 
PHACELIA CAM PAN U LAR IA. 
The campanulate flowers of this annual present an 
intense shade of blue seldom met with except in the 
Gentians, and even there the tint is not exactly the 
same. Eutoca viscida in the same family, perhaps, 
approaches it most closely, but the plant under 
notice is the finer of the two, and ought to be more 
extensively grown in large clumps, beds, or lines, in 
prominent places where its peculiar beauty would be 
seen to best advantage. In many private gardens 
much use is made of Nemophila insignis for pro¬ 
ducing an effect along the edges of borders in which 
various subjects are planted ; but the flowers at their 
best are only of a rich sky blue. In the case of the 
plant under notice it would be well to thin it out 
properly in its early stages in order to ensure as long 
a period of growth as possible, for by so doing the 
season of display is greatly prolonged. The leaves 
are roundly heart-shaped, and the petioles and 
stems are purple. 
DIANTHUS AM8IGUUS. 
The plant of this name is evidently closely allied to 
D. cruentus, but has larger flowers of a different 
shade of colour. They are aggregated in the same 
way in fascicled cvmes, and are of a rose-purple or 
red. The linear leaves are grass-like and glaucous, 
and the stems attain a height of 12 in. to 16 in. It 
seems capable of improvement, by seed-sowing and 
selection, to get larger flowers. The disc of the 
oetals is furnished with long, scattered, blackish hairs, 
that are more conspicuous than in many other kinds 
in cultivation. 
CHRYSANTHEMUM MONTANUM. 
Several hardy Chrysanthemums are now prized by 
hardy plant lovers, but that under notice is distinct 
from the sorts generally grown. In some respectsC. 
montanum approaches C. Leucanthemum, especially 
in habit, but both the leaves and the flowers are 
appreciably distinct. The plant grows about 12 in. 
to 18 in. high, and has white rayed flowers with a 
hemispherical and very prominent golden yellow 
disc. The stems are more leafy than those of C. 
Leucanthemum, the Ox-eye Daisy of our meadows ; 
the lower ones are spathulate, the middle ones 
oblanceolate, and the uppermost linear, but all are 
deeply cut or serrate. The stems are somewhat 
branched, each shoot terminating in a large flower 
head. The most striking feature of the latter is the 
elevated character of the disc, and it is for this reason 
obviously that the French give it the name of Puyde 
Dome. We noted several plants of it in the nursery 
of Messrs. J. Laing & Sons, Forest Hill. 
CAMPANULA GARGANICA AUGUSTA 
It is now pretty well-known amongst growers that 
C. garganica is a variable plant, and particularly so 
if raised from seeds. Some have smooth stems and 
leaves, while others are more or less densely hairy 
all over, and the flowers vary in size and depth of 
colour. The variety under notice is flowering 
amongst the collection of hardy plants at Forest 
Hill in the nursery of Messrs. J. Laing & Sons. It 
is of the smooth type, the stems, leaves and calyx 
being perfectly glabrous and shining. The pedicels 
of the flowers are purple, while the stems and leaves 
are more or less tinted with that hue, especially the 
leaves, which are netted with purple veins. The 
flowers are similar in form to the type, but of a much 
darker and richer hue. The variety is easily 
distinguishable amongst the other species and 
varieties. 
ORCHID NOTES TnD GLEANINGS. 
The Orchid Growers’ Calendar. 
Where no specially-constructed houses exist for 
the cultivation of these plants, a great deal will 
depend as to ultimate success in their culture on the 
making of a proper selection of sorts likely to be at 
home in the structures at hand. On this point I 
would advise amateurs to consult one of the leading 
nurserymen before making haphazard purchases, for 
I cannot help thinking if this were done more often 
than it is a lot of unpleasantness between employer 
and employed would be avoided, and well-grown and 
well-flowered plants be the result. 
East India House. — An abundance of moisture 
will be required in this house, with the admission of 
a corresponding amount of air, so that the atmosphere 
will not feel or seem stuffy when you enter the house. 
We syringe all our plants overhead now, but not 
heavily. A fine rose should be used for this opera¬ 
tion, or a very fine spray is made by putting the 
finger over the nozzle of the syringe. It will not be 
difficult to keep up a night temperature of 70°, with 
a rise of io° to 15 0 by day ; air is left on all night by 
means of the bottom ventilators, which are close to 
the hot-water pipes. 
Cattleya House. — This is just now gay with 
Cattleya gigas and C. g. Sanderiana, which is freer 
flowering than the type and carries more flowers to 
a spike. 
Odontoglossum Harryanum is making a good 
show. We have several ten-flowered spikes, which as 
far as I have seen is as many as they produce under 
cultivation. We shall now remove them to their 
summer quarters, the cool house, where the Miltonia 
Vexillarium is already quartered. The latter will 
now be repotted, but before doing so will receive a 
thorough clean up. Should there be any thrips, which 
is almost sure to be the case, as they have been left 
unchecked whilst the plants have been delighting 
their owner with their gorgeous blossoms, one or two 
dippings in tobacco water will soon settle them. 
Odontoglossum Rossii Majus. —What a little 
gem this is ! quite an amateur's plant. It takes up 
but little room, whilst the flowers to be got from a 
6-in. pan when doing well is surprising. Some three 
or four years ago it could be seen at the auction 
rooms in shoals, both in bloom and as imported 
pieces, but you rarely meet with it now in good 
condition. Flowered to death, I am afraid, must be 
the verdict. They last a long time in bloom, and 
unless the plant is relieved by cutting them off early, 
it must of necessity suffer, and the growths that follow 
be small. We treat ours somewhat different to most 
growers by giving them a rest after they have 
flowered in a light airy position, and water very 
sparingly, only enough in fact being given to keep the 
bulbs plump. They are just now breaking away and 
rooting freely from the base of the young growths, 
which is about one inch high, and will be at once 
repotted. - I prefer doing these now to any other time, 
as they are now in a condition to speedily take 
advantage of the new material supplied, which 
should be good peat and fresh sphagnum moss in 
equal parts. 
Temperatures. —Cattleya house, 65° at night,with 
a rise of 15 0 to 20° in the daytime with sun heat 
will do no harm. Cool house, 50° to 55 0 at night, 
with a rise of io° by day.—C. 
At the meeting of the Royal Horticultural Society 
on the 21st ult., the Orchids mentioned below were 
exhibited and accorded the awards recorded in each 
case. 
Cattleya Empress Frederick. 
A spike of a beautiful hybrid bearing four flowers 
under the above name was shown by Baron Schroder 
(gardener, Mr. H. Ballantine), The Dell, Egham. 
The seed parent was Cattleya mossise crossed with 
C. Dowiana, and as m : ght be expected something 
fine is the result. The flowers are of great size, and 
although the sepals and petals are not very highly 
coloured, the lip is so. The lamina is of great size 
and of an intense rich purple, margined with a 
pale almost white hue. Considering that C. Dowiana 
was used as the pollen parent we should have 
expected a greater amount of crimson and gold in 
the throat; but such as it is, the result is a very 
handsome and we are assured a unique Cattleya, for 
there is only one in existence. First-class Certificate. 
Laelia purpurata The Dell van. 
The varieties of L. purpurata are already pretty 
numerous, but that under notice appears to be quite 
distinct from any. The sepals and petals are pale, 
but the lamina of the lip is of a dark purple, heavily 
shaded with bronze as if there was a tendency to 
approach the type of L. grandis. Some cut flowers 
shown by Baron Schroder were accorded an Award 
of Merit. 
Sobralia Lucasiana. 
The stems of this Sobralia are about 2S ft. high, 
with broadly lanceolate, accuminate, many-nerved 
deep green leaves. A noticeable feature of it is the 
shortness of the various segments of the flower. 
The sepals are obiong and suddenly narrowed to a 
cuspidate point, and white or slightly tinted with 
blush. The petals are much broader, and tinted 
with lilac, but otherwise similar. The lip is bifid, lilac- 
purple, yellow on each side of the throat, and marbled 
with orange in the tube ; the tube externally is white 
slightly tinted with yellow. A First-class Certificate 
was awarded when shown by C. J. Lucas, Esq. 
(gardener, Mr. G. Duncan), Warnham Court, 
Horsham. 
Cattleya Amesias. 
In this we have a large flowered white Cattleya of 
similar habit, size, and form to the white varieties of 
C. Mossias. The sepals are oblong and white, the 
petals elliptic, undulate, and crisped at the edge, 
and similar in hue. The lip also is white with a 
large, orange, bifid blotch in the throat extending to 
the base ; the lamina shows the faintest tint of blush. 
Award of Merit.
