APRIL, IQII.| THE ORCHID REVIEW. 109 
are seen to be pushing roots, may be repotted in the compost previously 
recommended. Seedling Cattleyas, &c., may also be repotted at this season. 
The remarks respecting cleaning referred to under Cypripediums apply to 
these ; in fact, to everything, as no plant can flourish if in a dirty condition. 
’ CATTLEYA FLY must be watched for as the plants start into growth, and 
any abnormal growths should at once be taken off. It is better to take one 
or two clean growths off than let a brood of this terrible pest hatch out. I 
am pleased to say that if it is taken in hand it may be stamped out quickly 
and effectually. I have had odd plants show traces of it from time to time, 
which one is always liable to when receiving plants from different sources. 
Besides the remedies recommended on page 80, I would not hesitate to dip 
the plants entirely overhead in asolution of XL. All insecticide, and if used 
according to the instructions no harm will occur. This is only to be done 
in extreme cases. 
CaATTLEYA LAWRENCEANA will now be pushing its flower spikes, and 
should be kept on the dry side, and have a dry position in the house, as its 
flowers then will last much longer than in a damp situation. 
DENDROBIUMS of the nobile and Ainsworthii class will now be in full 
bloom, or perhaps just passing over and commencing to push their young 
growths. When these are seen to be pushing new roots is the time to 
repot, and they must have attention. The compost I recommend for them 
is equal parts of peat, polypodium, osmunda fibre and sphagnum moss, the 
pots or pans to be well drained, and no water to be given until the roots are 
seen to be travelling through the compost. A slight spraying over head on 
hot days will be beneficial until they get nicely established, then twice or 
three times a day will not hurt them, according to the weather. Don’t 
spray or syringe too much on dull cold days, or with a low temperature. A 
house of this beautiful class of plant, when properly grown and in full 
flower, makes a picture which is not easily forgotten. Seedlings of this 
family may also be repotted at this season. 
MILTONIA VEXILLARIA and its varieties are now pushing up their flower 
spikes, and should not be allowed to suffer for want of water, or else their 
spikes may be deformed and their flowers small. Before their spikes get 
very far advanced they should be thoroughly cleaned. They should also be 
fumigated every week until their flowers show colour, to prevent the ravages 
of thrip and other insect pests. As they come into flower they may be 
placed in their summer quarters. The best place I find for them is in a 
shady corner of the cool Intermediate house. 
ODONTOGLOSSUM CITROSMUM will now be pushing up its flower spikes, 
and should be watered with caution, as no water must be allowed to enter 
the young growth or they will decay, and with it the flower spike. I do 
not recommend the repotting of them until the flowers are over.
