THE GARDENING WORLD 
August 13, 1898. 
filled with the best varieties of Camellia japonica. 
One variety with dark claret flowers is here known 
as the black Camellia. Very pretty was a double 
variety of Lady Banks' Camellia, namely C. 
Sasanqua plena, with small, double pink flowers, 
and small leaves, being quite a distinct species from 
the Japanese one, so largely grown in some establish¬ 
ments here. All of the above are grown in 32 size 
pots and will be marketable this coming autumn. 
Azaleas and Camellias are also grown in houses near 
the office or bureau.

SCOTTISH HORTICULTURAL 
ASSOCIATION. 
The monthly meeting of this society was held at 5, 
St. Andrew’s Square, Edinburgh, August 2nd. The 
audience was treated to a remarkably fine exposition 
on " Orchids for Cut Flower and Decoration in 
Winter,” by Mr. Boyd—late foreman at the Glen, 
Innerleithen, now head gardener at Bellisle, Ayr¬ 
shire. Orchids as a rule require plenty of light and 
ventilation. Heating apparatus should be rather 
more than actually necessary and so save a forced 
drying heat. Afford copious supplies of water during 
growth. In watering, make sure of testing the com¬ 
post below its surface. Potting material—sphagnum, 
peat, crocks—only keeps the plants in position and 
lends moisture, but no nourishment. Cleanliness 
is a great item. For late autumn, Cattleya labiata 
should be grown in baskets, near the glass of an 
intermediate house. It flowers on the current year’s 
growth. Re-pot in February before the roots start. 
C. bowringiana from Central America, remains 
for three months in flower. It is a long-bulbed 
species and must be given more rest than short- 
bulbed sorts. It loves copious waterings, with liquid 
manure at times. 
Calanthe Veitchii is an attractive subject in the dull 
period. Shake out the old compost before roots are 
made, and in 6-in. pots put three bulbs. Use one- 
half fibrous loam, one-fourth of sphagnum, one- 
fourth of small crocks. Water carefully till fully 
established, then allow greater freedom, but withhold 
when growth is finishing. 
Dendrobium Phalaenopsis, varieties varying from 
deepest purple to pure white, are from North 
Australia. Grown in a warm division, using shallow 
baskets, and having good light, they throw up long 
racemes of Phalaenopsis-like flowers. 
Vanda caerulea sometimes has frost in its natural 
habitat. Pot in sphagnum and crocks, keeping the 
crown above the pot. Place it in the warm end of 
the East India House. Sophronitis, so decorative, 
thrives in the cool parts of the Cattleya house. 
Laelias with two to five flowers are very useful during 
November and December. When various varieties 
are grown they can be used to much effect. Naturally 
they receive nightly drenchings and are under full 
sunshine during day. Never shade unless the sun be 
scorching. Give air when 45 0 of heat is reached 
outside. The Trentham, or long-bulbed sorts, are 
later than the others. L. albida is a good one, but 
rather straggling. 
Coelogynes may be potted in peat and sphagnum 
shortly after flowering. Allow plenty of water and 
some liquid manure to established specimens. 
Cattleya Trianaei flowers in February or March in 
an intermediate house. It requires a long resting 
period. Never shade unless in very strong sun. 
Longer leaves and bulbs are got under shade, but 
such plants must lack bloom. Imported bulbs 
should be washed clean and hung base uppermost 
near the glass, being syringed daily till roots are 
emitted. They do better in baskets than in pots. 
Dendrobium wardianum made growths 4J ft. long, 
and covered with bloom, as a recompense to Mr. 
Boyd's care. Insert in well-drained pots,with sphag¬ 
num and peat, and plunge these in cocoa-nut fibre. 
Growths, 5 in. or 6 in. long, are pushed before roots 
are emitted. This necessitates care when watering. 
Syringe slightly overhead on warm days. When the 
last little leaf at the apex is seen, they are best taken 
to an early vinery with as much light as possible. 
From October till March afford only enough water 
to keep the psuedo-bulbs from shrivelling. They 
flower best when pot-bound. An annual top-dressing 
is mostly ail that is needed. D. nobile, being ever¬ 
green, takes more water in the resting stage. Other 
details are as for D. wardianum. Its profusion of 
blooms renders it useful for decorations and for 
hybridising. 
Cymbidium lowianum may be placed in an early 
vinery, and shifted to a later vinery when the first 
one becomes too cool. It goes to rest with the vines 
Odontoglossums were summed up as requiring (a) an 
equable cool temperature, ( b ) abundance of moisture, 
(c) sweet air, and ( d ) good, clear light. They are im¬ 
patient of pipe-heat. Use water no colder than night 
temperature, and damp the stages, paths, &c. Admit 
air when 40° Fahr. externally is registered. Shade 
when the sun raises the temperature to 6o° extern¬ 
ally. O. citrosum loves liberal waterings and a place 
at the cool end of the intermediate house. XI all 
Vaporiser is the best eradicator of pests on Orchids. 
No harm accrues to blooms. Adiantum farleyense 
is the only subject Mr. Boyd ever injured with this 
patent vaporiser. 
The exhibits forthcoming consisted of a dozen seed¬ 
ling Violas from Messrs. Dickson & Co., Waterloo 
Place. A brilliant yellow one—Walter Welsh— 
received certificate. They had also Lady Glamis 
Pinks (blood-red) and Snowflake (white). Messrs. 
James Grieve & Sons staged beautiful Carnations of 
great brightness. A seedling, named Britannia, was 
certificated. Its colour is deep salmon. Strawberry 
Richard Gilbert from Mr. Wm. Carmichael received 
a certificate. Geraniums came from Mr. Comfort; 
fine Spiraeas, in 6-in. pots, from another member; 
and a lovely truss of Nerium candidum from Mr. A. 
McKenzie, Trinity Grove. This Nerium is not 
described in " Nicholson’s Dictionary of Gardening,” 
and is a rare, pure white, large, semi-double. After 
some business and a vote of thanks to Mr. Boyd, the 
chairman announced next month's subject—” The 
Rose; Its History and hints on its cultivation.”—

ALPINE AND ROCK PLANTS. 
Coronilla cappadoica. —Several of the herba¬ 
ceous species of Coronilla are well adapted for 
trailing over the stones and boulders of the rock- 
work, for which they are very well adapted. Their 
long, rather woody roots penetrate the soil deeply, 
so that they flower profusely when various other 
subjects are suffering through the dry weather. The 
large, golden-yellow, and Pea-shaped flowers of C. 
cappadoica are produced in circular umbels, that is, 
the flowers of the truss point in every direction of 
the sky, and are carried quite clear of the glaucous 
foliage as it trails ever the ground. The tufts are, 
however, compact, and evergreen. When once 
established they will flower for many years in 
succession without further attention than keeping 
them free from weeds, and preventing tall subjects 
from overshadowing them, for they love the sun. 
Ramondia pyrenaica. —The hardiness of this 
European Gesnerad is now a well established fact. 
A suitable position must be selected for it amongst 
sandstone rocks, or other soft and porous material, 
in a position that is shaded from the direct rays of the 
sun for the greater part of the day. The woolly 
leaves are rather soft in texture, and lie close to the 
stones, so that the latter must never become dry and 
hot, or the Ramondia will be a failure. So long as 
the roots are in well-drained but moist soil, and 
squeezed in between cool and porous stones the plant 
will be happy and flower beautifully every summer. 
The purple flowers are in beautiful contrast with the 
pencil of golden stamens in the centre, and the 
orange spots at the base. 
Helianthemum Fireball. —The long continued 
dry weather has been rather hard upon the perish¬ 
able and ephemeral flowers of the Rock Roses. 
After a day’s hot sunshine the ground has several 
times been carpeted with the bright orange-scarlet 
flowers of this variety of the British Rock Rose. 
Another relay of flowers takes the place of the fallen 
ones day after day for weeks together. Even now 
the hoary or gray foliage looks appropriate on the 
rockery. If young plants are desired, take cuttings 
presently, but particularly a week or ten days after 
we get a good fall of rain to encourage fresh growth, 
and the rooting of them will be easy in a frame. 
Saxifraga aizoides.— Happy are those plants 
which have been planted near water, or where 
moisture is plentiful in summer. This Saxifraga, in 
a wild state, grows where water is constantly dripping 
down the rocks. The bright yellow flowers then 
look happy above a carpet of dark green, and, in 
fact, evergreen foliage.— J. Effe.

TRIALS AT CHISWICK. 
The fruit and vegetable committee of the Royal 
Horticultural Society met at Chiswick on the 22nd 
ult. to examine the Peas and Potatos submitted to 
trial. There were sixty-six stocks of the latter sent, 
but these were most of them passed over. Several 
varieties were considered promising, however, and 
it was decided that another examination should be 
made in August. 
It is to be regretted that the meeting of the Floral 
Committee was called for Wednesday, July 27th, for 
this brought it into collision with the annual exhibi¬ 
tion of the National Carnation and Picotee Society 
(Southern Section) at the Crystal Palace. A con¬ 
siderable amount of work was passed through hands, 
however, for there were many things to pronounce 
upon, and the list of awards was unusually long. 
Violas. 
In addition to the fifteen varieties which received 
the XXX distinction at the examination made by the 
committee on the 5th ult., the three undermentioned 
varieties were honoured 
Marchioness. —In addition to the XXX given on 
the 5th ult., an Award of Merit was granted Messrs. 
Dobbie & Co., of Rothesay, for this fine variety. 
The Mearns. —A showy flower of medium size 
and good form with light lavender-blue, upper 
petals, and deep purple lower ones. The eye is 
small, and rich yellow in hue. The habit is 
vigorous, and the plant free-flowering. XXX. Mr. 
John Forbes, Hawick, N.B. 
Bridegroom.— This is a charming, mauve- 
coloured, rayless variety of great beauty and refine¬ 
ment. The flowers are of medium size, first-class 
form, and are, moreover, produced in great numbers. 
The habit is distinctly 1 tufted,' and the plant should 
make a good bedder. XXX. Mr. John Forbes. 
Carnations. 
From a single packet of seed supplied by Mr. Jas. 
Douglas, of Edenside, Great Bookham, Surrey, a 
nice batch of seedings has been raised at Chiswick. 
An award of XXX was made to several of the most 
promising of these varieties. They were :— 
Firefly. —A rich scarlet self of great substance 
and broad smooth petal. 
Rosy Morn. —A large bright rose self with lacinia- 
ted petals of good substance, and an exceptionally 
free bloomer. 
Cygnet. —A pure white form of great merit, the 
flowers, although only of medium size, being in first- 
rate form, and the petals smooth, and of excellent 
substance. 
Black Douglas. —A rich, deep crimson self of 
great beauty, with petals round and flat, but with 
notched margins. 
Lady Primrose.—A bright primrose-yellow self, 
and an acquisition to this colour section. 
Goletta.—A fine flaked variety, the ground 
colour being clear white, and the stripes of carmine- 
rose. 
All the foregoing varieties have especially stout 
calyces which do not burst, and they are all very 
free flowerers, and, in fact, constitute good examples 
of a high type of border Carnation. 
Annuals. 
The trial of " Annuals ” has been one of the most 
extensive trials at Chiswick this year, and its useful¬ 
ness is not to be questioned, seeing how much we 
owe to the brilliancy and beauty of this class of 
easily grown plants. No fewer than 109distinct lots 
have been forthcoming from various sources, and 
the committee had thus a variety of claims to 
investigate and satisfy. 
Leptosiphon densiflorus roseus. —This pretty 
little plant is from 4 in. to 6 in. in height, of tufted 
habit, and with leaves arranged in dense terminal 
whorls, or' pseudo whorls, upon the dwarf upright 
stems. The flowers are about a third of an inch in 
diameter and bright rosy-pink in colour. Award of 
Merit. Messrs. J. Veitch & Sons, Ltd., Chelsea. 
Clarkia elegans rosea flore pleno. —This is 
rather a tall growing Clarkia, the plants being fully 
18 in. in height, and inclined to be straggling in 
habit. The showy, bright rose, double flowers are 
produced in long sparsely flowered racemes. XXX. 
Messrs. J. Veitch & Sons, Ltd. 
Godetia rosea alba. —Here we have a tall-grow¬ 
ing and distinct-habited Godetia. ihe plants are 
from 15 in. to 18 in. in height, the flowers being 
solitary in the axils of the leaves. The flowers them¬ 
selves are of medium size, bright pink in colour,
