their growth, Odontoglossum Roezlii, Phalsenopsis, Saccolabiums, 
Vandas, &c. If the seasons of growth and rest are watched the 
watering of these plants is soon mastered. The Angroecums require 
a plentiful supply when in growth, but must never be allowed to 
become too dry whilst at rest. This applies to the majority of Orchids 
except Dendrobiums, which like to be quite moist when in growth, 
but must have a thorough rest. For instance, if Dendrobium densi- 
florurn and 0. thyrsiflorum are kept moist whilst at rest they will fail 
to bloom. The Cypripediums in this house will require a plentiful 
supply of water when in full growth. Abundance of moisture is 
needed during the growing season, and shade from direct sunshine. 
The temperature best suited for this house is 60° to 65° as a minimum 
during the winter, with a proportionate rise during the spring and 
February, 1883, it grew freely and produced many flowering buds from the 
axils of the leaves on flower stalks about 1^- inch long. The buds were 
very small, hardly so large as hemp seeds, and it continued to produce them 
through the summer, when it was removed into a cool greenhouse, but none 
of the buds ever swelled above the size I have mentioned, and one after 
another fell off. I shall be glad to know if others have found the same 
difficulty in blooming this plant, and if not, what system of cultivation 
they pursued to obtain a more satisfactory result.—A n Amateur. 
ROYAL CALEDONIAN HORTICULTURAL SOCIETY. 
April 2nd and 3rd. 
The spring Show of this thriving Society was held in the large Waverley 
Market, Edinburgh. The prizes offered were divided into seven sections, five 
summer. Each house is benefited by 5° extia fire heat by day when 
required, but the temperature should never be allowed to rise too high 
by fire heat, as it causes the plants or compost to become dry ; 
besides, it is not healthy for the plants.—A Grower. 
CRINODENDHON HOOKERIANUM. 
Can any of your correspondents tell me anything of their experience 
in growing the plant Crinodendron Hookerianum, otherwise Tricuspidaria 
hexapetala, described on page 98, vol. vi., of your Journal ? I purchased a 
small plant from Messrs. Veitch as one of their novelties in November, 
1881. It showed signs of suffering in a cool greenhouse in the winter 
following, but being placed in a yinery when, the \ines were forced in 
of these being for gardeners and amateurs, the remaining two for nursery¬ 
men. The first five were for plants, Hyacinths, Ac., cut flowers, fruits, and 
vegetables. The two classes set apart for nurserymen were for plants 
Hyacinths, and cut flowers. 
Plants. —One of the main features in the plant classes were the prizes 
for a tabla of plant 3 20 feet long by 5 feet wide, arranged for effect. Only 
two competitors entered, Mr. Grossart, gardener to J. Buchanan, Esq., 
Oswald Road, being placed first, many well-flowered Orchids being repre¬ 
sented, such as Dendrobium Wardianum, D. Jamesianum, D. thyrsiflorum, 
Odontoglossums Alexandra and cirrhosum, Cattleya Trianse, &c., with a few 
Palms and other fine-foliage plants, making a bright arrangement. The 
second table, from Mr. A. Paul, Gilmore Place, was rendered less attractive 
by the formality of the arrangement; some good Orchids were, however, also 
shown, and a number of small plants of Primula nivea were very pretty.
