house. Owing to their thick glaucous leaves these plants are able to with- 
stand drought better than Cypripediums which have thinner leaves, there- 
fore should only receive water when necessary, and in no case should they 
be watered overhead. Seedling Cypripediums, as they become large 
enough, should be placed in small pots, so that they may get well rooted 
before the winter. 
DenpRoBiuMs.— D. Phalenopsis and D. formosum are autumn-flowering 
species, and if they have not already been repotted they should be attended 
to without delay. Being plants which produce few roots, shallow pans are 
the best receptacles, and as they have a short growing season, they should 
receive generous treatment from the time they commence to push until the 
completion of the pseudobulbs. Dendrobiums of the evergreen section, 
such as D. Farmeri, may also have attention as regards repotting, should it 
be necessary. A clean fibrous compost answers their requirements. 
Owing to the difficulty in obtaining material and labour, undoubtedly many 
more plants will have to stand over as regards repotting than in normal 
times, therefore a close watch should be placed upon the application of 
water to the compost in which any plants are growing, especially where 
this is known to be more or less decomposed. 
Ca:LocynEes.—The species which produce pendulous flower spikes are 
best grown in shallow pans, which may be suspended when in bloom, where 
their flowers will be seen to great advantage. Such plants as C. asperata, 
with its hybrid, and others that produce flowers at this season, may be 
repotted, if necessary, when their growths are well advanced, and about to 
push forth roots. Owing to the immense quantity of water necessary for 
the welfare of these plants when in full growth, the pots or pans must be 
well drained, and the compost should be made moderately firm. They 
delight in abundance of heat, but resent strong sunshine. C. pandurata, 
and others of a rambling nature, are difficult to keep in a compact form, 
therefore it is advisable to sever the rhizome behind the second or third 
bulb, and when the back bulbs have produced a break they should be 
potted into small receptacles, when they will soon make flowering plants. 
GENERAL REMARKS.—Many people are suffering from the great 
shortage of labour, and only with the greatest difficulty are they able to keep 
their plants growing and carry on generally. In the interest of horticulture 
it is essential that the many valuable plants in the numerous collections in 
the country should be maintained in good health, so that there is not too 
much arrears to make up when normal times return. Most of us have 
Some experience of dealing with refractory subjects, and horticulturists are 
always at war with the enemies of their plants, and now that so many are 
away there must be no relaxation, or the result will soon be apparent in 
reduced vigour and a diminution in the number of flowers.
