Juty-Aucust, 1919.] THE ORCHID. REVIEW. 113 
Plants of Cattleya Warscewiczii (gigas) that have recently gone out of 
bloom, also those that have completed their season’s growth without 
flowering, should now be exposed to more sunlight and air, and placed in 
slightly cooler quarters. They should still be afforded water whenever they 
become dry, but much less will suffice than when in active growth. The 
repotting of this Cattleya and its varieties should be done, if needful, 
immediately new roots are observed to be pushing from the last made 
pseudobulbs. After repotting, only sufficient water will be needed to 
prevent undue -shrivelling of the pseudobulbs or the roots from perishing. 
They will then enter upon a long season of rest, so far as top growth is 
concerned, but the roots will continue to extend through the new compost 
right through the winter months, provided the proper conditions are 
maintained. During winter a dry, airy position in the Warm Cattleya’ 
house, where they receive all the light possible, will provide suitable 
quarters for them. There are other species of this large family, and 
innumerable hybrids, which may be treated precisely in the same manner. 
A season of rest and growth for plants which have attained their ‘normal’ 
stature should be carefully observed. 
CypRIPEDIUMS of all sections, being now well rooted, must onwards 
have copious supplies of water, as if allowed to become dry for any length of : 
time they are readily attacked by thrips, which soon disfigure their tender 
foliage. During fine, bright weather these plants may be syringed or 
sprayed once or twice a day, which will be the means of keeping attacks of 
insect pests down and the plants clean. Clean soft tepid water should only 
be used for this purpose. - 
MILTONIA VEXILLARIA AND ITS HYBRIDS.—Towards the end of August 
the majority of these plants will have made sufficient growth for any 
necessary repotting to be done. This operation may be carried out any 
time during July and August provided the young growths are about to push 
forth roots from the base. There was a time when these plants were 
potted in the early spring months, but after careful observation I was 
convinced many years ago that this was not the best season to undertake 
this work, and time has thoroughly convinced me of its correctness. If 
pottéd any time during the two later months mentioned, they get thoroughly . 
established before the winter, and make most satisfactory growth, and 
produce good flowers. Being surface rooters, they are best grown in half 
pots or deep pans, as if a great depth of material is used the best results are 
not attained. After potting, water must be sparingly applied until the 
roots freely enter the new material, which should be of the same nature as 
that used for Odontoglossums.. A moist position in the Intermediate house, 
where they can be shaded from strong sunshine, answers their requirements.
